摘要： A drive circuit for brushless DC motors comprising a rotor and a stator with at least one stator coil includes a commutation device which supplies commutation pulses of drive current to the stator coil(s). The commutation device senses the rotor position and calculates current rotor speed therefrom. The rotor speed is then used to shift the commutation currents according to predetermined functions. The shifting of commutation currents is occasioned by shifting either or both of the ignition part of a commutation pulse and the extinction part of such pulses.

摘要： The invention relates to a circuit arrangement for self-commuting control of a brushless, permanently excited direct current motor. Said circuit arrangement determines the commutation interval by evaluating the induction signal of a signal phase. A capacitive interference suppression component is arranged between the signal phase and an adjacent motor phase in the commutation cycle in order to suppress interferences of the induction signal. The capacitive interference suppression component is dimensioned in such a way that interfering influences of the power-switch element upon the induction signal are compensated for. This makes it possible to more accurately determine the momentary rotating position of the rotor and, hence, a differentiated control or adjustment of performance-influencing manipulated variables during operation. This has positive effects upon the efficiency, the power/weight ratio and energy consumption of the motor and enables stable operation.
