Latest Patents
Gruntleitner holds a patent for a reversible direct current motor with a permanent magnet rotor. This invention involves reversing the polarity of the desired speed voltage of a speed control device and the commutation sequence of the current flowing in the stator windings. The motor utilizes a voltage proportional to the electromotive force (EMF), obtained from the motor voltage by I.times.R compensation, as the actual speed voltage for the speed control device. Notably, the polarity of the voltage proportional to the EMF is reversed when the direction of rotation signal changes.
