Simply put, LCR meter measures the characteristic parameters of separate components, such as resistance value, capacitance value, etc. It generally needs to be tested independently after power failure. Multimeter is a multifunctional measuring instrument. It can test separate components, electrical signal characteristics, and has some other measurement functions.

LCR meter is a special measuring tool used to measure the characteristic parameters of electrical components. L refers to inductance, C refers to capacitance, and R refers to resistance. In addition, the LCR meter cannot be used to measure other parameters. Moreover, the inductance, resistance or capacitance must be measured when the circuit is powered off. Because it is a dedicated instrument, the measurement accuracy is high.

Industrial water chiller is a kind of water cooling equipment that can provide constant temperature, constant current and constant pressure. The principle of the chiller is to inject a certain amount of water into the internal water tank of the machine, and the water is cooled by the refrigeration system. Afterwards, the water pump inside the chiller injects cryogenically frozen water into the equipment that needs to be cooled. The chilled water takes away the heat inside the machine and returns the high-temperature hot water to the water tank for cooling. In this way, the circulation exchange cooling can achieve the function of cooling the equipment.

When the same stepper motor works with different drive schemes, the torque-frequency characteristics are also very different.
When the stepper motor is working, the pulse signal will be added to each phase winding in turn in a certain order (the ring distributor in the stepper motor driver controls the way the winding is energized and de-energized).
Unlike other motors, the nominal rated voltage and rated current of a stepper motor are only reference values. Because the stepper motor is powered by pulse, the power supply voltage is its highest voltage, not the average voltage. Therefore, the stepper motor can work beyond its rated value range. However, when choosing, it should not deviate too far from the rated value.
The stepper motor does not accumulate errors: The accuracy of the general stepper motor is 3%-5% of the actual step angle, and it cannot be accumulated.

The brushless DC motor is a device that converts electrical energy into mechanical energy. By consuming electrical energy, mechanical energy can be obtained to achieve certain needs. What are the applications of BLDC motors? Brushless DC motors can be used in the small home appliance industry. The most common electric fan is to use brushless DC motors to convert electrical energy into mechanical energy to turn the electric fan, bringing us coolness. In addition, lawn mowers in the garden industry and electric drills in the power tool industry all work with brushless motors.

Brushless dc motor
The brushless DC motor is composed of a motor body and a brushless motor driver. It is a typical mechatronics product. Because the brushless DC motor runs in a self-control mode, it will not add a start winding to the rotor like a synchronous motor started under heavy load under variable frequency speed regulation, nor will it cause oscillation and loss of step when the load changes suddenly. The permanent magnets of small and medium-capacity brushless DC motors now mostly use high magnetic energy level rare earth neodymium iron boron (Nd-Fe-B) materials.

Stepper motor
A stepper motor is a motor that converts electrical pulse signals into corresponding angular or linear displacements. Every time a pulse signal is input, the rotor rotates an angle or moves forward. The output angular displacement or linear displacement is proportional to the number of input pulses, and the speed is proportional to the pulse frequency. Therefore, the stepper motor can be called the pulse motor.

LCR meter is a special measuring instrument used to measure the characteristic parameters of electrical components. L is inductance, C is capacitance, and R is resistance. The LCR meter is a dedicated meter with high measurement accuracy. As a precision instrument, if the operation is not standardized, it is easy to damage the instrument and affect the accuracy of the measurement result. This article will summarize the common failures and precautions in the use of LCR meters to avoid failures, helping users to use the LCR meter correctly.

Working Principle of BLDC Motor
The BLDC motor is mainly composed of the motor body, position sensor, electronic commutation circuit and driver. The motor body is similar in structure to a permanent magnet synchronous motor, but it has neither cage windings nor other starting devices. The stator windings are generally made into multiple phases (three-phase, four-phase, five-phase and so on). The rotor is composed of permanent magnet steel according to a certain number of pole pairs (2p=2, 4...). In a brushless DC motor, the armature winding is arranged on the stator, and the permanent magnet poles are arranged on the rotor. The position of the armature winding of each phase of the stator relative to the magnetic field of the permanent magnet of the rotor is sensed by the rotor position sensor electronically or electromagnetically. Moreover, it uses its output signal to drive the corresponding power switch transistor connected with the armature winding through an electronic conversion circuit according to a certain logic program, and commutate the current switch to the corresponding armature winding. With the rotation of the rotor, the rotor position sensor continuously sends out signals, causing the armature winding to be continuously energized in sequence, and the energization state is constantly changed. As a result, the direction of the current flowing in the coil conductor under a certain magnetic pole is always the same, and the rotor keeps running.

Clamp meter is the abbreviation of clamp ammeter. It is a portable measuring instrument that can directly measure the AC current of the circuit without disconnecting the circuit. It is called a clamp ammeter because of its shape with a movable opening in the shape of a clamp. Common clamp meters do not have the ability to measure AC and DC voltages of 1kV or above. It is recommended not to measure parameters higher than this voltage to avoid personal electric shock.

In the machinery industry, almost every machine tool equipment needs to use a control transformer. It is often used as a local lighting power supply, signal lamp or indicator power supply, and as a control circuit power supply in electrical equipment. However, when in use, you may encounter the problem of the control transformer being burned out. What is the cause?

With the construction and development of industry, many industries such as metallurgy, electronics, and coating have put forward higher requirements for the extraction of gas or particles from equipment. The large demand for industrial production and the rapid development of technology have made the production process of vacuum pumps continue to improve. Gradually occupy a larger market share in industrial production. With the continuous improvement of the level of vacuum pump manufacturing technology, the structural design of vacuum pumps is more refined, and different equipment structures also enable vacuum pumps to work in different industrial environments. Different types of vacuum pumps are driving the industry with a rapid growth momentum. Rapid development. The following form is a brief list of common problems and maintenance methods.

The quality of the vacuum pump is decided by its mechanical structure and the quality of the oil, it must be well protected when using the vacuum pump. When using distilling volatile organic solutions, it will be absorbed oil that will lead to the increase of vapor pressure and the decrease of vacuuming efficacy. If it is acid gas, it will corrode the oil pump, and if it is steam, it will destroy the vacuum pump from turning oil into emulsion.

Vacuum pump is a kind of equipment that evacuates the pumped container to obtain a vacuum by means of mechanical, physics, chemistry or physical Chemistry methods. The gas is absorbed in from the air inlet and enters the cavity of the frontline pump through the ventilation/isolation valve. In the pump, the gas is conveyed. When the inlet is closed by the blade, the gas is conveyed and compressed. During the transferring process, the oil is transferred from the oil injection port and inhaled into the cylinder.
