YVP frequency controlled three phase motor is the latest generation of special three-phase asynchronous motors for variable frequency speed regulation launched by our company. This vfd drive motor is a universal variable frequency speed regulating motor developed and designed on the basis of Y/Y2 series motors. It can be well matched with the inverters of different manufacturers in the current market, and the frequency conversion range is 5-100Hz or 3-100Hz. YVF motor has the advantages of high efficiency, low noise, obvious energy saving effect, stable driving, wide speed range, fast response and excellent performance. This series of motors are widely used in applications requiring high-precision speed regulation such as numerical control, textiles, metallurgy, etc., and can also be applied to fan and water pump loads for the purpose of energy saving. The average energy saving rate of a single machine can reach 30-60%.

FAQ
What is the difference between variable frequency motors and ordinary motors?
The efficiency and temperature rise of the motor
Regardless of the type of frequency converter, different degrees of harmonic voltage and current are generated during operation, making the motor run under non-sinusoidal voltage and current. Refusal to introduce the information, take the currently commonly used sine wave PWM inverter as an example, its low-order harmonics are basically zero, and the remaining high-order harmonic components, which are about twice as large as the carrier frequency, are: 2u+1 (u Is the modulation ratio).
High-order harmonics will cause the increase of stator copper loss, rotor copper (aluminum) loss, iron loss and additional loss, the most significant is the rotor copper (aluminum) loss. Because the asynchronous motor rotates at a synchronous speed close to the fundamental frequency, the high-order harmonic voltage cuts the rotor bar with a large slip, which will cause a large rotor loss. In addition, the additional copper loss due to the skin effect needs to be considered. These losses will cause the motor to generate additional heat, reduce the efficiency, and reduce the output power. For example, if an ordinary three-phase asynchronous motor is operated under the condition of a non-sinusoidal power supply output by the frequency converter, its temperature rise will generally increase by 10%-20%.
