Abstract

The invention provides a double rotating shaft electrical motor. An outer rotor coil is powered or two rotor coils are powered simultaneously, so the two coils produce two rotating magnetic fields which interact on each other to produce torque on the rotors, thereby the two rotors rotate towards two reverse directions. The invention has the advantages of improved efficiency and wider applicability.

Description

technical field [0001] The invention relates to a double-rotating-shaft motor. Background technique [0002] At present, the motor is composed of a stator and a rotor, which cannot play a special role in occasions where forward and reverse rotation are required at the same time and are mutually restrained. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned defects and provide a double-rotating-shaft motor. [0004] The technical solution of the present invention is: a double-rotating shaft motor, characterized in that: an outer rotor and an inner rotor are provided, the inner rotor iron core coil is sleeved in the outer rotor iron core coil, and there is a small gap between the inner rotor and the outer rotor. Both rotors are equipped with bearings, the inner rotor bearing is fixed on the end face of the outer rotor, the outer rotor bearing is fixed on the machine base, and the corresponding slip ring carbon brush is ...
