Latest Patents

David S Zendzian holds a patent for a brushless DC motor controller. This invention includes a track and hold circuit that responds to the voltage at the motor centertap terminal and the voltage across at least one motor winding. It determines the position of the rotor by detecting zero crossings of the back EMF of the unenergized winding, effectively reducing susceptibility to noise. The output of the track and hold circuit is interpolated to minimize the effects of pulse width modulation noise on rotor position detection. The drive signals controlling a plurality of electronically controlled switches are chopped to control the speed of the motor. Additionally, a PWM disable circuit is provided to selectively disable a PWM signal, further reducing noise effects on rotor position detection.
