Abstract
Reconfiguration of stator winding sections of each phase of a multiphase motor is controlled for successive ranges of speed during which the motor can be expected to operate to obtain optimum operating efficiency throughout the entire operating range. All winding sections for a stator element are energized throughout the motor operating speed range but connected, through appropriate switches, in different circuit configurations for respective portions of the speed range. The switches are activated by a controller in response to a sensed motor speed signal. The reconfiguration of stator winding sections may be incorporated within a motor control system that is adaptive to control various motor parameters in response to sensed conditions as well as user input commands.
