Answer：The fan is an important wind pressure component of the motor ventilation and heat dissipation system . It compensates for the wind pressure loss when the cooling medium passes through the air path, transports a certain flow of cooling medium to the h...
Answer：From the perspective of the motor itself, the high vibration value of the motor is mainly related to the dynamic balance of the rotor. From the perspective of the motor's external conditions, the installation quality of the motor and the host, t...
Answer：There are many cases where the motor starts and runs at low voltage. At this time, the load should be reduced as much as possible or used intermittently. Generally, the voltage of the motor is allowed to fluctuate within the range of +10%~-5%. For ex...
Answer：From the perspective of determining the responsibility, motor winding failures can be divided into two categories: manufacturing quality and usage problems. Winding turn-to-turn, phase-to-phase and ground faults can basically be attributed to manufac...
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.
