Latest Patents

Dugan holds a patent for a "Control system for synchronous brushless motors utilizing torque angle." This innovative patent describes an improved motor control system for a pulse width modulated synchronous brushless motor. The system provides means for adaptively controlling the 'torque angle,' which is the angle between the rotating magnetic field created by the stator windings and the rotor field created by the permanent magnets on the rotor. The relationship between these two magnetic fields is controlled based on load and speed, ensuring the optimum operating point is achieved at all times. By controlling the torque angle, the back EMF constant K.sub.e (V/RPM) and the torque constant K.sub.+ (torque/ampere) of the motor can be effectively varied.
