    • An electric motor in an appliance and a method of controlling the motor to achieve speeds greater than a base speed of the motor is provided. To achieve speeds above the base speed of the motor, field weakening can be implemented by applying a field weakening angle to a phase advance angle between a desired stator flux and a rotor flux. The field weakening angle can be based on the current speed of the motor. The field weakening angle can be a fixed angle and can be determined by comparing the current speed of the motor with a predetermined threshold. In addition, the magnitude of the electrical signal applied to the motor can be adjusted during field weakening based on a desired speed of the motor where the electrical signal can be a voltage.
