More Information
Summary:A low-voltage high-power frequency changing triphase asynchronous motor comprises a frame, a stator, a rotor and a rotation shaft, wherein the ratio between armature calculated length and pole distance ratio equals to or is larger than 4.5, and a draught fan is installed on non shaft-extension end of the motor. The low-voltage high-power frequency changing triphase asynchronous motor has the advantages that the volume is small, the end portion of a motor coil is shrank, the leakage reactance is decreased, the cooper consumption is reduced, and the efficiency is enhanced, thereby being particularly applied to situations when equipment installing space is small and high-power output is required.
