摘要：
In a D.C. motor having a position detector for detecting predetermined rotor positions and an electronic commutation circuit for connecting the stator coils to the power supply in a predefined cyclic order (and for disconnecting them) in dependence upon detected predetermined rotor positions, the no-load speed is limited by delaying the connection of a next stator coil in response to a new detection of a next one of the predetermined rotor positions, until a predetermined delay period has elapsed after a previous detection of another rotor position that lies a predetermined distance ahead of the newly detected rotor position.
