Abstract

The invention relates to the technical field of motors, in particular a three-phase cage type asynchronous motor. The three-phase cage type asynchronous motor comprises an armature, a driving shaft is fixedly installed at the outside center of the armature, the driving shaft is connected with an asynchronous motor for driving the driving shaft to rotate; an output shaft is built in the armature, a magnetic pole is fixedly sleeved and installed out of the output shaft, and an exciting winding is built in the magnetic pole; gaps are formed between the magnetic pole and the armature and between the output shaft and the armature; and the tail part of the output shaft is provided with an electric collecting ring. The three-phase cage type asynchronous motor disclosed by the invention is reasonable in design, wide in speed adjustable range, smooth in speed adjusting, large in starting torque and small in control power, and has the advantages of being reliable in running, light in weight and cheap in price.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a three-phase cage-type asynchronous motor. Background technique [0002] The rotor speed of the three-phase asynchronous motor is lower than that of the rotating magnetic field. The relative motion between the rotor winding and the magnetic field induces electromotive force and current, and interacts with the magnetic field to generate electromagnetic torque to realize energy conversion. The traditional three-phase asynchronous motor has complex structure, small speed regulation range, small starting torque, large control power and poor performance, which cannot meet the production needs. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a three-phase cage-type asynchronous motor by overcoming the deficiencies in the prior art. [0004] The technical solution adopted by the present invention to solve the technical prob...
