PUMP MOTOR CONTROLLER ABSTRACT OF THE DISCLOSURE A pump motor controller for making pump motor speed independent of fluid pressure at the inlet and outlet of the pump. The pump motor controller senses motor speed and compares it with a reference input. If motor speed differs from the reference input, a drive circuit receives a signal relative to the difference between motor speed and the reference input and increases or decreases the motor speed such that it converges to the reference input. The drive circuit controls motor speed by using forward commutation to speed up the pump motor, and reverse commutation to brake the motor. The motor controller also provides a frequency discriminator, operable to stop the motor by initiating reverse commutation when the reference input falls below a threshold value.
