Answer：AC servo motor is a device that converts electrical energy into mechanical energy. It mainly consists of a stator and a rotor. When alternating current is supplied to the stator, a rotating magnetic field will be generated. The rotor will rotate and ...
Answer：Brushless DC motor, the English abbreviation is BLDC (Brushless Direct Current Motor). The stator of the motor is a coil, or winding. The rotor is a permanent magnet, which is a magnet. According to the position of the rotor, the microcontroller is u...
Answer：The motor must be reliably grounded. The grounding method and grounding resistance should comply with electrical safety management regulations such as the "Grounding Design Specifications for Industrial and Civilian Electric Power Installations"
Answer：During the operation of the motor, parameters such as current, rotation speed, and the relative position of the rotating shaft in the circumferential direction are monitored in real time to determine the status of the motor body and the dragged equip...
Answer：Resolver is a commonly used position sensor in motor control. The function of the resolver is to accurately measure the position, speed and direction of rotation of the motor rotor, and transmit these signals to the electronic control. The motor is c...
Answer：Torque, speed and power are the three main parameters describing power systems in mechanical engineering.
Answer：As a parameter that motor users are more concerned about, the service coefficient can reflect the performance of the motor. Today, let’s briefly analyze what the motor service coefficient is? How to reflect the performance of the motor?
Answer：The permanent magnet motor uses permanent magnets to generate the magnetic field of the motor. It does not require an excitation coil or an excitation current. It has high efficiency and a simple structure. It is a good energy-saving motor. With the ...
Answer：There are significant differences between brushless DC motors and permanent magnet synchronous motors in many aspects. The structure, control strategy, back electromotive force waveform, current harmonics, torque ripple, cost performance, switch cond...
Answer：Fan motor refers to the electric motor used to drive the fan. Fans usually consist of impellers, motors and brackets, of which the motor is the core part. The main function of the fan motor is to convert electrical energy into mechanical energy, ther...
