REIHENSCHLUSSMOTOR, INSBESONDERE UNIVERSALMOTOR, MIT EINER BREMSEINRICHTUNG
摘要:
The invention relates to an inverse speed motor, especially a universal motor, with a braking device and a stator having a field winding and a rotating armature powered via a commutator and brushes and a suitable circuit for switching the field winding to braking mode and a braking device inducing an additional magnetic field during braking. The inverse speed motor is to be constructed in such a way that, when it is switched from motor to generator or braking mode, the braking process is simply triggered via self-excitation. To this end, to the set of pole shoes (12) of the stator are allocated means for inducing a magnetic field, preferably at least one additional coil (20), and at least one pole arc (16) of at least one pole shoe has a groove (18) or a pair thereof and the additional coil (20) is arranged in the groove (18) or pair or grooves.
