Abstract
A redundant brushless drive system, including a coil () having first and second phase windings operable independently of one another and first and second independently operable sensor groups for the rotational position of a rotor () and for commutation of the phase windings. The first and second sensor groups are positioned along the motor axle one-behind-the-other parallel to each other and symmetrical to the motor axle (). An encoder circuit board () is configured such that an association of the sensor groups (GG) to a phase winding (WW) is configurable such that either the first sensor group (G) is used for controlling the first phase winding (W) and the second sensor group (G) for controlling the second phase winding (W), or the first sensor group (G) is used for controlling the second phase winding (W) and the second sensor group (G) for controlling the first phase winding (W).
