Absolute encoders are generally capable of outputting 360° with 8 to 12 bits. There are many optical channel engraving lines on the absolute encoder optical disc, and each engraving line is arranged with 2 lines, 4 lines, 8 lines and 16 lines in turn, the shaft encoder obtain a set of unique binary codes (Gray codes) from the zeroth power of 2 to the n-1th power of 2.

A brushed DC motor is a rotating motor that converts DC electric energy into mechanical energy or converts mechanical energy into DC electric energy with a built-in brush device. Different from the DC brushless motor, the brush device is used to introduce or draw DC voltage and DC current. BDC motor is the basis of all motors, which has the characteristics of fast starting, timely braking, smooth speed regulation in a large range, and simple circuit control.

Butterfly valve is a kind of regulating control valve with a simple structure. The butterfly valve can be used for switching control of low pressure pipeline medium, which rotates around the valve shaft to achieve opening and closing. Butterfly valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media.

RC servo motor, short for radio control servo motor, can also be regarded as a DC servo motor, but its characteristics and application fields are different from DC servo motors. RC servo motors are mostly used for steering control of remote control models. Potentiometers (variable resistors) are used to detect the position, and the rotation angle can reach 180°.

AC synchronous generator is a mechanical device that converts other forms of energy into electrical energy. The AC synchronous alternator is driven by a water turbine, steam turbine, diesel engine or other power machinery, which converts the energy generated by water flow, air flow, fuel combustion or nuclear fission into mechanical energy and then transmits it to the generator, at last, it converted into electrical energy by a generator. Brush alternator is widely used in industrial and agricultural production, national defense, science and technology and daily life.

Single phase motors generally refer to low-power single phase asynchronous motors powered by a single phase AC power supply. It is also called a single phase induction motor. This kind of motor usually has two phase windings on the stator, and the rotor is of ordinary squirrel cage type. The distribution of the two phase windings on the stator and the different power supply conditions can produce different starting characteristics and operating characteristics.
Single phase motors have a large production volume and are closely related to people's daily lives. Especially with the improvement of people's living standards, the consumption of single phase motors for household appliances is also increasing.

Squirrel cage induction motor is the simplest and most widely used type of asynchronous motor. Its rotor coil is cast aluminum and shaped like a squirrel cage, so it is called a "squirrel cage motor". These motors are a specific kind of induction motor, which uses the electromagnetic induction effect to transform electrical current into rotational energy. This article will explain the principles of squirrel cage motors, their specifications, and what kinds of applications they are used for. This way, we can make informed choices when choosing the right motor.

Dosing pumps are available in thick sections and non-adjustable flow, the former is more widely applicable. The flow star is mainly adjusted by changing the stroke length, such as changing the crank radius, the plunger returns when the backstop position and the plunger rod and crosshead connection between the evolution, but also by changing the number of reciprocations or both methods to adjust the flow.

Speed reducers primarily serve two purposes. First, they can multiply the torque generated by the input power source to increase the amount of usable work. Second, they are used to reduce the input power source speed to achieve desired output speeds. For this reason, a smaller, less expensive motor with a speed reducer may enjoy wider application fields than a larger motor without one.

Explosion-proof motor is a type of motor with explosion-proof performance. It is a kind of motor that can be used in flammable and explosive places, and it does not produce electric sparks during operation. It has a structure different from that used in ordinary environments. It can prevent the combustible gas and dust outside the motor from entering the motor to the greatest extent, or even if it enters, it will not ignite the combustible gas and dust in the surrounding environment from the flame out of the casing when short-circuited and caught in the interior.

The gear motor is a widely used reduction drive equipment, and the drive structure is assembled by a drive motor and a gear box, also known as a "reducer". There are many types of drive motors. DC motors, brushed motors, brushless motors, stepper motors, coreless motors, and servo motors can all be used as drive motors. The gearbox can adopt planetary gearboxes, cylindrical gearboxes, parallel gearboxes, worm gearboxes, screw gearboxes, and so on. Depending on the different drive motors, it can be divided into DC gear motors, stepping geared motors, brushed gear motors, brushless gear motors, hollow cup geared motors. It also can be divided into planetary gear motor, gear reducer, worm gear motor, parallel gear reducer, screw gear reducer according to the structure of the gearbox. Reducer motors with different structures have different application characteristics.

A linear servo motor is a direct drive solution where the load is directly connected to the moving portion of the motor. Direct drive linear motors are available in a variety of configurations (iron core, U-channel, tubular) but ultimately work the same. Linear motors operate with an AC power supply and servo controller, which are often the same as those used for rotary servo motors. The linear motor primary part is connected to the power supply to produce a magnet field. By changing the current phase in the coils, the polarity of each coil is changed.

DC cooling fan is an important cooling device for modern industrial machinery, which is widely used in machinery cooling because of its good cooling effect, long service life, simple structure, easy installation and many other features, can also be used in automobiles, power supplies and household equipment. Brushless DC cooling fans have the characteristics of low noise, stable operation and longer service life. You can choose from a variety of sizes and speeds.

A variable speed motor is a motor that has a variable frequency drive or similar technology installed to control motor speed and torque, by placing these key factors of motor performance under the control of the operator, variable speed motors offer a means for products and production facilities to greatly reduce the amount of energy being consumed by the motors in their devices. Unlike single-speed motors that run at full capacity and then cycle off, a variable-speed motor can operate at high speeds, low speeds or anywhere in between, ramping up and down like a dimmer switch. Variable speed motors are widely used in places that require energy-saving continuous operation and frequent work, such as fans, air compressors, injection molding machines, reducers, water pumps, vacuum pumps, etc.

Selection of industrial heaters to understand what classification it has, to understand the characteristics of different industrial heaters, according to the application of the scene to choose the right product. Industrial heaters are common oil heater, electric heater, gas heater. In the following, ATO online store will introduce something about this topic.

The temperature controller is a kind of intelligent temperature control instrument. It has the functions of temperature curve programmable or fixed-point constant temperature control, multiple PID regulation, output power limiting curve programming, manual / automatic switching, soft start, alarm switch output, real-time data query, communication with computer, etc. It combines digital temperature meter and ZK thyristor voltage regulator into one, which integrates temperature measurement, regulation and driving. The meter directly outputs thyristor trigger signal, which can drive all kinds of thyristor loads. It is used in all kinds of high and low voltage switchgear, dry-type transformer, box type substation and other related temperature application fields. In addition to understanding what the temperature controller is, we also need to know its three "how": how to work, how to use, and how to choose the temperature controller for better use of ATO.   

Permanent magnet synchronous motor is an AC motor that generates torque by the interaction of the excitation magnetic field supplied by a direct current and the rotating magnetic field of the armature, and rotates at a synchronous speed. It belongs to AC motors, and the stator windings are the same as synchronous motor. Because its rotor rotation speed is the same as the speed of the rotating magnetic field generated by the stator winding, it is called synchronous motor.

Transformer is a device that transform AC voltage, current and impedance. It uses the principle of electromagnetic induction to transform AC power of one voltage level into AC power of another voltage level. When an AC current is passed through the primary coil, an AC magnetic flux is generated in the iron core, causing a voltage (or current) to be induced in the secondary coil. It is composed of an iron core and a coil. The coil has two or more windings. The winding connected to the power supply is called the primary winding, and the remaining windings are called the secondary winding.

Transformer mainly uses the principle of electromagnetic induction to work. The specific process is when an AC voltage U1 is applied to the primary side of the transformer, and the current flowing through the primary winding is I1, the current will generate alternating magnetic flux in the iron core, which makes the primary winding and the secondary winding electromagnetically connections.

The air blower is mainly composed of the following six parts: motor, air filter, blower body, air chamber, base (and oil tank), drip nozzle. The blower operates eccentrically on the rotor offset in the cylinder, and changes the volume between the blades in the rotor slot to suck in, compress, and discharge air. During operation, the pressure difference of the blower is used to automatically send the lubrication to the drip nozzle and drip into the cylinder to reduce friction and noise, while keeping the gas in the cylinder from returning. This type of air blower is also called a sliding vane blower. There are many types of air blowers, mainly divided into the following categories.

Vibration meter is an instrument used to measure the peak value, peak-to-peak value, average value or root mean square value of vibration such as velocity, acceleration and displacement. The vibration meter can be applied in mechanical manufacturing, electric metallurgy, general aviation etc. The main parts of this instrument are integral differential circuit, amplifying circuit, voltage detector and meter head. The integral differential circuit is used to complete the integral differential operation between the above vibration quantities. Generally, integral and differential operational amplifiers can be used, low-pass filters and high pass filters can also be used to complete integral differential operations. However, we should pay attention to this instrument's application frequency range when we are using it for calculation. The vibration meter can only obtain the total intensity (vibration level) of the vibration, but cannot obtain other information, so its scope of using is limited.
