Title:
PERMANENT MAGNET SYNCHRONIZING ELECTRIC MOTOR
Document Type and Number:
WIPO Patent Application WO/2011/108363
Kind Code:
A1
Abstract:
Disclosed is an electric motor capable of highly efficient driving, as well as self-starting, as a permanent magnet synchronizing electric motor. A permanent magnet synchronizing electric motor is configured from a rotating element (100) wherein permanent magnets are attached to an iron core, and a fixed element (200), further comprising a polyphase winding (202), which is positioned upon the periphery of the rotating element. A polyphase current is applied to the polyphase winding (202) of the fixed element (200) that is applied to the permanent magnet synchronizing electric motor. As a configuration thereof, at least two permanent magnets (110a, 110b) are positioned exposed equidistantly in prescribed positions upon the cylindrical face of the rotating element (100) and in opposition to the fixed element (200). Damping windings (basket-shaped windings) (121a, 122a, 121b, 122b) are positioned in different locations from the positioning locations of the permanent magnets (110a, 110b) in the circumference direction of the cylindrical face. When activated, the motor starts up as an induction motor using the damping windings, and rotates as a synchronized electric motor by way of the permanent magnets when a synchronization velocity is reached.
