The motor manufacturer reminds that the variable frequency speed motor is a motor used in extraordinary places with a frequency converter. The difference between it and the ordinary high-efficiency motor is the addition of an independent fan.And the power of the independent fan comes from a separate power supply, which guarantees the cooling performance of the variable frequency motor at low speeds.

　　Other Hubei Wanbang motor manufacturers also remind users that frequency conversion motors can use frequency converters to adjust the motor speed, and then achieve the goal of energy saving according to the load environment.An ordinary motor is a device with a reliable speed and cannot be adjusted.

　　From the layout point of view, there is no big difference between the frequency conversion speed control motor and the ordinary high-efficiency motor. In addition, the frequency conversion motor coil copper wire specification is high, and the insulation system design is more suitable for the frequency conversion speed control utilization, so that the high frequency output of the frequency conversion cabinet The current has little effect on the motor, which guarantees the useful life of the variable frequency motor.

　　The manufacturing processes of ordinary high-efficiency motors and variable-frequency speed-regulating motors are very different.Ordinary motors, power frequency motors, only need to think about the startup process and the working environment at one point in the power frequency, and then design the motor; while variable frequency motors need to think about the startup process and all the working environments within the scope of frequency conversion, and then design the motor.There are also the following points:

　　1. Since the PWM widened wave output by the inverter imitates sinusoidal exchange electricity and contains a large number of harmonics, it generally needs to be filtered by a reactor before the gas enters the ordinary motor, otherwise the ordinary electricity will have a fever;

　　2. In order to adapt to the PWM widening wave output by the inverter, imitating the sinusoidal exchange electricity contains a large number of harmonics.Specially built variable frequency motor.The dip dyeing can actually be seen as a reactor plus an ordinary motor;

　　3. That is to say, the cross section of the frequency conversion motor of the same power is larger than that of the ordinary motor.The number of turns of the coil should be multiple and the wire diameter should be large; the insulation should be high, and the special cooling fan motor should be used.

　　4. In order to meet the needs of weak magnetic speed regulation, consider the bearing capacity and the dynamic balance of the high-speed rotor;

　　5. This kind of variable frequency motor does not have better torque characteristics, but surrenders the need for ordinary motors not to adapt to PWM wide wave imitating sinusoidal exchange electricity;
