2hp Motor And Vfd

Title:

YVFE3 VARIABLE FREQUENCY LV MOTOR

Brief Introduction

Thermal design is another important manifestation of the adaptation of the two to different operating conditions.Power-frequency motors mostly use self-fan cooling. The cooling fan is rigidly connected coaxially with the rotor, and the speed decreases as the motor speed decreases.The cooling structure is only designed according to the rated speed. Once it enters low-speed operation, the fan air volume is insufficient, which is prone to heat accumulation problems; frequency-conversion 2hp motor and vfd generally use independent forced air cooling, and the cooling fan is driven by a separate power-frequency power supply. Regardless of the motor's own speed, the air volume is always stable.

At the same time, the cooling rib design of the base is denser, or the area of the heat sink is increased to strengthen the heat dissipation capacity under special operating conditions such as low speed and high frequency, so as to avoid failures caused by excessive temperature. Differences in rotor design also affect operating performance.The rotor guide strips of power frequency motors are designed according to the rated torque. The starting torque is insufficient at low speeds, and additional losses are easily caused by harmonics at high frequencies.

The rotor guide strips of frequency conversion 2hp motor and vfd are mostly made of highly conductive materials, or optimized for double-cage and deep-groove cross-sections, which not only improves the starting torque at low speeds, but also enhances the anti-loss ability at high frequencies, and the rotor balance level is higher, which can reduce vibration and noise over a wide speed range and ensure smooth operation.
