Document Type and Number:
Japanese Patent JP3197278
Kind Code:
B2
Abstract:
A driver circuit for an electronically commutated electric motor, in particular a stepper motor, having a full-bridge circuit (I, II) per motor winding (L1, L2) having a current sensor resistor (R), having a measured value store (C5), and having a regulation circuit (OP1-OP5) which regulates the overall current flowing through the driver circuit during part of the driver phases in such a manner that this overall current corresponds with an overall current value which flows other than in the control phases and is stored in the storage circuit (C5), in order to suppress alternating components in the overall current which is supplied via the supply voltage lines (cables, leads).
