The difference between variable frequency motor and ordinary motor
Answer 1: Inverter motor - used in motors with special occasions for inverters. It differs from ordinary motors in that it adds a strong cooling fan, and the power of the fan comes from a separate power supply, which cannot be taken out from the main motor. The role of the strong cooling fan is to ensure the cooling of the motor at low speeds.
Answer 2: The variable frequency motor can adjust the speed of the motor and achieve energy saving according to the load. A normal motor is a device with a fixed speed and cannot be adjusted.
Answer 3: There is no big difference, except that its coil distribution capacitance is smaller, the resistance of the silicon steel sheet is larger, so that the influence of the high frequency pulse on the motor is small, and the inductance filtering effect of the motor is better.
Answer 4: The manufacturing process of ordinary motors and variable frequency motors is very different. The ordinary motor, that is, the power frequency motor only needs to consider the starting process and the working frequency at one point, and then design the motor; and the variable frequency motor needs to consider all the working conditions in the starting process and the frequency conversion range, and then design the motor.
