Latest Patents

Hans Spirk holds a patent for a "Method and apparatus for driving a brushless D.C. motor." This invention involves a brushless D.C. motor that includes a rotor and multiple stator windings, which create a stator field when powered by a bridge circuit. A microprocessor drives the bridge circuit using pulse-width modulation logic. The motor operates by triggering the commutation of the stator field, while monitoring the voltage induced by the rotor in a non-energized stator winding. This monitoring helps determine if the voltage reaches, exceeds, or falls below a threshold voltage. The invention also calculates a delay time between triggering the commutation and the voltage response, which is crucial for optimizing the timing of the next commutation.
