Title: Dynamic braking of series motor by supply reversal - uses short circuiting diode connected across armature terminals to oppose normal current flow
Inventor: KNORPP ERNST ING GRAD
IPC: H02P3/12
Filed: 1976-11-18
Abstract: The dynamic braking arrangements for a series motor is modified by permanently connecting a diode (3) across the armature (1) terminals in a sense opposing the normal supply voltage. When braking is required the supply contactor (4) changes the applied polarity. The motor then acts as a generator and, since its polarity has changed, current is circulated through the diode (3). A loading or limiting resistor (6) may be connected in series with the diode to control the braking effect and limit the short circuit current. A capacitor (5) may be placed in series with the reversed supply to ensure that the field current decays to zero. The circuit is particularly useful where the series field winding (2a, 2b) is split either side of the armature.
