Abstract

The invention discloses a high-efficiency three-phase asynchronous motor with an unequal-turn forward rotation winding, which is characterized in that a plurality of heat dissipation grooves are further formed in a rear end cover, the motor is powered on, a rotating shaft is made to rotate through the electromagnetic action, a transmission gear is driven to rotate through a tooth part on the rotating shaft, the transmission gear is meshed with the tooth part, and the number of teeth of the transmission gear is less than the number of teeth of the tooth part, so that the rotating speed of the transmission shaft is higher than that of the rotating shaft, the rotating gear on the transmission shaft drives the driven gear to rotate so as to drive the output shaft to rotate, air circulation of the heat dissipation grooves is accelerated through rotation of fan blades, and then the airflow dissipates heat of the interior of a casing. The number of teeth of the driven gear is consistent with the number of teeth of the rotating gear, so that the rotating speed of the output shaft is consistent with the rotating speed of the transmission shaft, the fan blades rotate faster, and the heat dissipation effect of the motor is better.

Description

technical field [0001] The invention relates to the technical field of asynchronous motors, in particular to a high-efficiency three-phase asynchronous motor with unequal-turn forward-rotating windings. Background technique [0002] Most of the existing three-phase asynchronous motors fix the fan coaxially on the rotating shaft of the motor. The speed of the fan is equal to the rotating speed of the rotating shaft. Due to the structural limitation of the fan, the cooling effect of the fan on the motor is poor when the rotating speed of the fan corresponds to the rotating shaft. Contents of the invention [0003] The purpose of the present invention is to provide a high-efficiency three-phase asynchronous motor with unequal-turn positive-rotating windings, aiming to solve the problem that most of the existing three-phase asynchronous motors in the prior art fix the fan coaxially on the rotating shaft of the motor, and the fan is In the case of corresponding rotating shaft s...
