Abstract
The utility model discloses a low voltage high power frequency converting speed regulating three-phase asynchronous electromotor, which comprises a stand, a bearing, a stator, a rotor and a fan. The bearing, the stator, the rotor and the fan are arranged on the stand. The utility model is characterized in that a ventilation duct is arranged in the stand; the rotor adopts a center plate structure; and the rotor is provided with an inner fan and a wind scoop. The iron core material of the stator and the rotor adopts a cold-rolled silicon steel plate. The stand is provided with radiating ribs. The utility model has good ventilation and radiating effects, and adopts the independent fan to force the ventilation of the radiating ribs on surface. The thermal deformation caused by welding the steel plate and the electromotor performance can not be influenced. The stability of long-term constant torque running is ensured when the electromotor is at low speed.
Description
Technical field:
The utility model relates to a kind of low-pressure high-power frequency control threephase asynchronous.
