Answer："Servo" - the word comes from the Greek word "slave". People want to use the "servo mechanism" as a handy tool for taming, and act in accordance with the requirements of control signals. Before the signal arrives, the rotor s
Answer：Generally speaking, motor noise has little correlation with power frequency. When motor designers design motors, they usually pay great attention to the operating characteristics at the specified power frequency, rarely adopt unconventional electroma...
Answer：The main feature of the wound rotor three-phase asynchronous motor is that its rotor winding can be connected in series with an external resistor, and the total resistance of the rotor winding circuit can be changed by changing the resistance value o...
Answer：The motor starting method has the risk of burning the motor. The motor starting method mainly considers the motor power, wiring method and whether the motor needs frequency conversion requirements. The common motor starting methods are 1. Full voltag...
Answer：Leakage is the current leakage caused by electrical products including motors, insulation damage or other reasons. Under normal circumstances, the conductors of the motor windings are isolated by insulation and are in relatively independent channels,...
Answer：Under the dual-carbon strategic layout, drive motors, as the core components of new energy vehicles, need to pay more attention to the development of high efficiency, miniaturization, and intelligence. In recent years, in order to further improve the...
Answer：The motor is namely an engine. The starter rotor is driven to rotate by the energized coil in the magnetic field, and the small gear on the rotor drives the flywheel of the engine to rotate. An electric motor (Electric Motor, see Figure 1), also kno...
Answer：Answer: The output horsepower between the 3KW single-phase motor and the 3KW three-phase motor is equal. Because horsepower is also a unit of power, it is just an old concept of an industrial revolution. The concept of horsepower was named by James ...
Answer：I believe everyone is familiar with the motor. Recall the physical DC brushed motor in high school. The principle has been the same for thousands of years. A permanent magnet (magnet) acts as a stator, and a coil acts as a rotor. According to the pri...
Answer：The maximum torque is one of the most important power parameters of the motor, also called the stall torque. Under the rated voltage and frequency, gradually increase the load until the motor speed drops suddenly, the shaft end torque of the motor co...
