Method for determination of motor parameters of electronically commutated motors during operation involves motor which has stator with majority of stator blocks and permanent magnetic rotor is cooperating with this stator

摘要

The method involves a motor which has a stator with a majority of stator blocks and a permanent magnetic rotor is cooperating with this stator, during operation which induces alternating voltage into the stator blocks. A power amplifier is arranged at the stator blocks to control the current supply of the stator blocks. During the operation the energy input to the motor is interrupted whereby the rotor further rotates. Independent claims are also included for the following: (A) Electronic commutator motor; (B) Method for determination of temperature dependent motor parameters and (C) Method for operation of electronically commutated motor.
