Gearbox is an important part widely used in the rotation of the system. It consists of two or more gears, including at least one drive gear with a certain diameter, and one smaller gear connected to the drive mechanism (electric motor, wind turbine, diesel generator, and so on).
An induction motor or an asynchronous motor is an AC motor that works on the principle of electromagnetic induction. That is, the rotor obtains torque under the action of the rotating magnetic field generated by the stator, and then the rotor rotates. Since the rotor speed is not the same as the speed of the rotating magnetic field (synchronous speed), the induction motor is also known as asynchronous motor. Induction motors are popular in the industry, since they are simple to build and economical. The following are some essential things you need to consider when buying an induction motor.
Water chiller is a machine that removes heat from a liquid coolant via a vapor-compression, adsorption refrigeration, or absorption refrigeration cycles. Air cooled water chiller and water cooled water chiller are eh two types of the water chiller. How to choose the right chiller is a problem worth our attention. Because water chillers for sale in various websites. In the following, we will tell some tips to help you choose a suitable, high quality and cheap water chiller.
Hybrid stepper motor is a stepper motor designed by combining the advantages of permanent magnet and reactive. It is divided into 2 phase, 3 phase and 5 phase. The two phase stepping angle is generally 1.8 degrees, the three phase stepping angle is generally 1.2 degrees, and the five phase stepping angle is generally 0.72 degrees.
Digital timer relay has the advantages of accurate measurement, simple setting, multiple protection functions and high speed, etc. It is an ideal substitute for traditional electromagnetic and static relays. Digital time relay is generally used in automation equipment electrical cabinet, street lamp control, water pump timing operation control, equipment timing start and stop control and other occasions. In this article, we will experiment to see how it is set up and works.
Stepper motor is one of many motors. Although it is the same as other motors in terms of functional types, it is different from other types of motors in terms of working principle and structural design. The operation form, functional performance, applicable aspects and performance of different stepping motors are different from other types of motors.
Chain hoists are divided into air chain hoist and electric chain hoist. Air operated chain hoist is a lifting device that uses compressed air as a power source to drive internal mechanical parts to lift and heavy loads. It is composed of a lifting mechanism, a walking mechanism and a gas distribution system. Pneumatic chain block hoist has the characteristics of high frequency, infinitely variable speed and safety. Electric chain hoist is a special lifting equipment powered 3 phase full copper motor to move heavy loads.
The position control mode of the servo motor is very common in the precision movement of industrial automation. The principle is that the servo motor drive carries out precise control of the motor movement after receiving the position pulse and direction pulse of the pulse generator (PLC, single chip microcomputer). Servo motor has three control modes: speed control, position control and torque control. This time we will introduce the position control mode of ATO new servo motor, using PLC to pulse.
There are three commonly used non-contact liquid level sensors, namely capacitive liquid level sensors, ultrasonic liquid level sensors, and separate photoelectric liquid level sensors. The non-contact liquid level sensor can detect the liquid level without contacting the liquid. With this advantage, the application field of the non-contact liquid level sensor has been greatly expanded. The common feature of these three types of non-contact liquid level sensors is that they are not affected by liquid color, corrosiveness, pressure, density, etc., and because the sensor does not directly contact the liquid, it is more hygienic, and it is convenient for users to clean the container, add liquid, etc.
Servo motor can control speed, position accuracy is very accurate. It can convert voltage signals into torque and speed to drive control objects. Servo motor rotor speed is controlled by the input signal, and can respond quickly, in the automatic control system, used as an executive element, and has the characteristics of mechanical and electrical time constant is small, high linearity, can receive the electrical signal into the motor shaft angular displacement or angular velocity output.
Temperature controllers are very common field display instruments and are used in various industrial occasions. Our Dual Channel PID Temperature Controller has an RS485 interface, which can transmit temperature control information to the upper computer through the Modbus RTU protocol for unified information management.
In this blog, we are gonna explain how to connect a Pt100 sensor to the PID temperature controller. To let this happen, we'll use a humidity sensor, a solid state relay and a conventional relay as well as the Pt100 sensor. Follow us to learn the detailed steps.
In addition to the brushless DC motor is often used in industrial automation, we often see its application in electric vehicles. And what we want to introduce today is an infrastructure that it uses in electric vehicles.
The Pt100 temperature sensor is an instrument that converts a temperature variable into a transmittable, standardized output signal. Pt100 is a platinum thermal resistor, and its resistance will change with temperature. 100 after Pt means that its resistance value is 100 ohms at 0°C, and its resistance value is about 138.5 ohms at 100°C. Mainly used for the measurement and control of industrial process temperature parameters. Its working principle is that when the PT100 is at 0 degrees Celsius, its resistance value is 100 ohms, and its resistance value will increase approximately uniformly as the temperature rises. But the relationship between them is not a simple proportional relationship, but should be closer to a parabola.
To let ATO BLDC motor drive fully perform its speed control function, it is very important for you to make sure that the hall sensor is properly connected to the driver. In this blog we’re gonna illustrate the correct wiring steps.
The analog signals used in the industrial control process are generally standardized, such as 0~10V, 0~20mA, 4~20mA, etc., which can greatly solve the problem of signal compatibility, and also provide equipment for the expansion of use. Convenience. Our VFD also supports analog signal input control. Let me introduce the use of 4-20mA to control the frequency of the VFD.
Variable frequency drive (VFD) is an electric power control equipment that uses frequency conversion technology and micro-electronic technology to control ac motors by changing the frequency of the motor's working power supply. Variable frequency drive by internal IGBT off to adjust the voltage and frequency of the output power supply, according to the actual needs of the motor to provide the required power supply voltage, so as to achieve the purpose of energy saving, speed regulation.
A stepper motor is an actuator that converts electrical pulses into angular displacement. When the stepper driver receives a pulse signal, it drives the stepper motor to rotate a fixed angle in the set direction, and its rotation runs step by step at a fixed angle. The angular displacement can be controlled by controlling the number of issued pulses, so as to achieve the purpose of controlling the displacement. At the same time, the speed and acceleration of the motor rotation can be controlled by controlling the pulse frequency, so as to achieve the purpose of speed regulation. The rotor inside the servo motor is a permanent magnet.
Brushless DC motor is composed of motor body and driver, which is a typical mechatronics product. High speed brushless motor refers to the motor without brush and commutator (collector ring), also known as the motor without commutator. Brushless DC motor is widely used in automobiles, tools, industrial control, automation and so on. We also need to know how to use it.
