Answer：when choosing a motor protector, it should be determined based on the specific use environment and requirements.
Answer：The winding and embedding of motor windings may have adverse effects on the insulation layer of the electromagnetic wire. Whether it is enameled electromagnetic wire or mica wire used in molded windings, it is difficult to avoid such problems.
Answer：Under the guidance of the national energy-saving and low-carbon policy, improving motor efficiency is an irreversible direction; for motors whose efficiency levels do not meet the current mandatory standards, whether they are in service or on sale, h...
Answer：In recent years, the application areas of permanent magnet motors have been gradually expanding, especially in variable load occasions such as fans, water pumps, and air compressors. The application and energy-saving effects of permanent magnet motor...
Answer：To solve the problem of starting the power frequency cage motor, soft starter or reduced voltage starter can be used, but there are many additional equipment and complicated control links, which is not as simple and flexible as the inverter power sup...
Answer：the overall performance of the motor is closely related to the rotor slot shape, and how to select the rotor slot shape often requires appropriate adjustments depending on the actual application objectives.
Answer：The stator and rotor cores of the motor are made of laminated sheets. In theory, the sheets should be stacked neatly, and the slots of the cores can be neat and smooth after lamination. However, in the actual production and processing process, the sl...
Answer：For motors of different series, the designed temperature rise margin is different; for motors of the same series, the physical space may be very tight due to various factors such as power, installation, and component versatility. The non-compliance o...
Answer：The shaft voltage is the potential difference between the two ends of the shaft, the local part of the shaft, and the shaft to the ground during the operation of the motor. When the shaft voltage is high, it may cause the bearing lubricating oil film...
Answer：The wound rotor motor uses a resistor in series with the rotor to ensure that the motor has a sufficiently large starting torque and a very small starting current (the starting current multiple is approximately equal to the starting torque multiple),...
