PERMANENT-MAGNET MOTOR Russian patent published in 2005 - IPC

FIELD: electrical engineering; drive motors.

SUBSTANCE: proposed permanent-magnet motor has twin stator incorporating permanent magnets in the form of U-section solenoids disposed on inner surface of stator and two rotors, one per each permanent-magnet section, in the form of arched bars rigidly coupled with axis of revolution, as well as coupling and flywheel. Rotor magnet is attracted by stator solenoid due to interaction of unlike-polarity poles of stator and rotor magnets which turns rotor through definite angle until like-polarity poles of stator and rotor magnets are aligned. As rotor magnet end front along its running leaves dead zone, it is pushed out of stator magnet and ensures continuous rotary motion. When rotor passes through dead zone, its rotary motion is maintained by flywheel and dc machine running as motor supplied with power from storage battery that functions to help rotor pass through dead zone. Upon leaving dead zone rotor shaft load reduces and dc machine runs as generator. In his way electrical energy is recuperated and used for booster charge of storage battery.

EFFECT: enhanced power output and efficiency.
