Title:
A PERMANENT MAGNET SYNCHRONOUS ARRAY-TYPE AC MOTOR WITHOUT BEARINGS
Document Type and Number:
WIPO Patent Application WO/2009/015517
Kind Code:
A1
Abstract:
A permanent magnet synchronous array-type AC motor without bearings includes
a rotor that uses U-shape permanent magnets and a stator that uses U-shape windings.
An appropriate combination of the number of the rotor poles and the number of the
stator poles is used to design the synchronous speed. Electronic elements control
the stator windings to power on. The load capacity of the motor depends on the number
of the stator windings that are powered on.
