摘要： An apparatus for controlling a direct-current electric motor having a contact-less commutator, a rotor in the form of a permanent magnet and a stator with a three-phase winding is disclosed, said apparatus comprising a magnetic clutch of which the drive part is coupled with the output shaft of the motor and the driven part supports the rotor of a pickup responsive to the position of the rotor of the motor and the rotor of a braking electric machine, which is adapted to vary automatically the position of the axis of the magnetic flux of this rotor position pickup relative to the axis of the magnetic flux of the rotor of the motor and thus to adjust the speed of the motor. The apparatus ensures a high degree of stabilization of the motor speed within a wide range of controllable speeds and is employable, e.g. in various tape-driving mechanisms.
