    2000W Variable Speed Motor Details

    Tips: Special Design of Variable Speed Motor.

    Electromagnetic design:
    For variable speed motors, since the critical slip is inversely proportional to the power frequency, it can be started directly when the critical slip is close to 1. Therefore, overload capacity and starting performance do not need to be considered too much, but the key issue to be solved is how to improve the motor The adaptability of non-sine wave power supply. The method is generally as follows:
    1) Reduce the stator and rotor resistance as much as possible.
    Reducing the stator resistance can reduce the fundamental copper loss to compensate for the increase in copper loss caused by higher harmonics.
    2) In order to suppress the higher harmonics in the current, the inductance of the motor needs to be appropriately increased. However, the rotor slot leakage reactance is large, the skin effect is also large, and the copper loss of high-order harmonics is also increased. Therefore, the magnitude of the motor leakage reactance must take into account the rationality of impedance matching in the entire speed range.
    3) The main magnetic circuit of the variable frequency motor is generally designed to be unsaturated. One is to consider that higher harmonics will deepen the saturation of the magnetic circuit, and the other is to appropriately increase the output voltage of the inverter in order to increase the output torque at low frequencies.

    Existing reviews of 3hp (2kW) Variable Speed Motor, 3 Phase, 2P/ 4P/ 6P
    Highly recommend it!
    Some one I knew has this type of variable speed motor, and he recommended. It works really good exactly like it’s supposed to and I also recommend this variable speed motor.
