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...
Answer：Both types of AC asynchronous motors and PMSM have their own advantages and disadvantages, and there is no obvious difference between them. Only better adaptation in specific application scenarios can the maximum advantages of each type of motor be b...
Answer：The motors of new energy vehicles generally use AC asynchronous motors or permanent magnet synchronous motors, which are one of the core components that convert electrical energy into mechanical energy. Compared with internal combustion engines in tr...
Answer：The drive motor is one of the three main components of electric vehicles, and its importance is extremely important for electric vehicles. The drive motor of an electric vehicle replaces the engine in a fuel vehicle. It uses a motor control machine t...
