The motor has at least one field winding (14,16), at least one commutating armature (12) in series with the at least one field winding and supplied from a voltage supply (17) in motor mode and an arrangement (S1-S3) for changing over to braking mode. The arrangement for changing over to braking mode has enables bridging of the armature and external stimulation of at least one field winding by the voltage supply in braking model. |
