A pulse controller for controlling the energization and regenerative braking of a DC electric motor. An electronic switch connects the motor to a power source during motor driving and controls motor current during regenerative braking, the switch being rendered alternately conductive and non-conductive during both driving and braking and the ratio of conductive to non-conductive periods being controlled. The conductive and non-conductive periods are interrelated such that, regardless of the ratio between the periods, during regenerative braking the switch alternates between its conductive and non-conductive states at a rate sufficient to automatically maintain the generated motor current within desired maximum and minimum limits.
