摘要:
A drive motor assembly for a power driven wheelchair comprises: a statorhousing for containing field coils of a stator of the motor assembly at leastone sensor disposed in the stator housing for sensing rotation of the motor amemory storing motor error parameter data including data of errors of the atleast one sensor, the memory being embedded in the stator housing and aconnection for accessing the error parameter data of the memory from thestator housing. The motor error parameter data may be accessed from theembedded memory of the drive motor by a programmed motor controller for use incontrolling the drive motor. Also, the motor error parameter data may beembedded in the drive motor by the steps of : controlling the motor through atleast one predetermined drive pattern sensing motor rotation during the drivepattern and generating signals representative thereof, deriving errorparameter data of the drive motor from the generated signals programming amemory with the derived error parameter data and embedding the memory in thedrive motor.
