ABSTRACT:
Methods and apparatus for controlling a motor are provided. The motor may be operated in a fluid system having a variable static pressure acting on the motor. The method including operating the motor at a first substantially constant torque level, varying the static pressure of the system, receiving a torque selection signal from external to the motor, and operating the motor at a second substantially constant torque level, the level corresponding to the torque selection signal.
