Title:
AN INTEGRATED POSITION RESOLVER FOR HYBRID SYNCHRONOUS ELECTRIC MOTORS
Document Type and Number:
WIPO Patent Application WO2003005530
Kind Code:
A3
Abstract:
An integrated position resolver for hybrid synchronous electric motors. The present invention represents new improved integrated position resolver for hybrid synchronous electric motors which uses the magnetic flux of the motor also for operation of the resolver. The solution is achieved with an additional measuring coil in the motor and with a small change in control electronics. The measuring coil (1) measures changes of the magnetic flux through the parmanent magnet (4) and the control electronics provides the phase shift of the PWM pulses in successive phases.
