Title:
MOTOR WITH DOUBLE ROTORS STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2003/030335
Kind Code:
A1
Abstract:
In a motor having a structure with double rotors and the rotors are positioned on the main shaft. A cylindrical stator is fixed to a motor housing and two rotors are fixed to the same turning shaft in the motor housing. Two rotors are separated each other with the stator being set between the rotors and some magnetic material are set on the opposite surface of the rotors. As the invention has a double rotors structure, there is no magnetic stalling torque of rotors' magnetic field to the stator and no energy waste for overcoming the magnetic stalling torque such that the motor has less energy waste for activation, bigger activation load, less no load waste and bigger output rating. So the invention can save energy on and increase efficiency. It can be used for asynchronous AC motor, synchronous AC motors, no electric brush DC motor and synchronous AC generator.
