ANGLE ESTIMATOR, MOTOR CONTROLLER, MOTOR DRIVER, MOTOR DRIVING SYSTEM, IMAGE FORMING APPARATUS, AND CONVEYANCE DEVICE

An angle estimator includes correction means for correcting a phase of an error parameter to obtain a corrected error parameter and estimation means for calculating an estimated speed and an estimated angle of the motor based on the corrected error parameter. The error parameter is a function of an...

Beschreibung
Zusammenfassung:	An angle estimator includes correction means for correcting a phase of an error parameter to obtain a corrected error parameter and estimation means for calculating an estimated speed and an estimated angle of the motor based on the corrected error parameter. The error parameter is a function of an angle error representing a difference between an actual angle and an estimated angle of a motor.
