ABSTRACT:
In a multi-winding motor of the type which develops switching spikes from respective drive signals, separate interference suppression apparatus is not provided for each motor winding to be triggered, but rather interference suppression circuitry is shared between respective winding drive signal paths. In a first arrangement, a single resistor-capacitor impulse suppression network is commutated between all motor winding connections in predetermined phase relation with the application of drive currents to the respective windings. In a further arrangement, a single impulse suppression circuit is used to cyclically couple the respective low power motor trigger signals to the respective high power winding drive amplifies, which suppression circuit precludes the generation of interference pulses at the interface between the drive circuitry and the motor to be driven.
