More Information
Summary:A motor controller for an electric motor includes a drive circuit that regulates power supplied to a stator of the electric motor to turn a rotor. The motor controller includes a communication interface that receives coefficients. The motor controller includes a processor coupled to the drive circuit. The processor receives an airflow rate demand, computes a speed, computes a torque set point as a function of at least a sum of first and second terms. The first term is defined as the first coefficient multiplied by the airflow rate demand raised to a power greater than one, and the second term is defined as the second coefficient multiplied by the speed raised to a power greater than one. The processor controls the drive circuit based on the torque set point to supply electrical power to the electric motor.
