ELECTRIC MOTORS

摘要

An electric motor with a current commutator independent of the frequency of the power supply current. It comprises at least one exciter (15) applied onto the rotor (13) and indicative of the position of a polarity plurality of the rotor; a sensor-detector (17) that detects the presence or position of the exciter (15) when it passes by upon rotation with the rotor; and a circuit (18) for inversion of the direction of the electrical current at the coils (11', 12') of the inductor, the sensor (15) controlling the circuit of inversion (18) in response to signals of presence supplied by the exciter (15).
