Abstract

963,647. Control of D.C. motors; battery charging arrangements. SEVCON ENGINEERING Ltd. Nov. 1, 1962 [Nov. 25, 1961], No. 42225/61. Headings H2H and H2J. A self-propelled vehicle comprises traction motor A which is adapted to operate as a generator for charging a storage battery, the charging current being controlled by a pulse generator circuit P, and means are provided for adjusting the pulse frequency and thereby the mean power supplied to the battery. When the vehicle is running in the forward direction and the brake is applied, switch S1 is closed to energize motor field winding W2, and a signal is transmitted to render gated diodes 2 conductive and diodes 1, 1a, non-conductive. Charging current then flows through diodes 2, the circuit P, and diodes 2a. The rate of battery charging increases with depression of a brake pedal and consequential movement of the slider of a potentiometer which controls the pulse rate. A similar process of regeneration takes place when the vehicle is reversed, but in this case the gated diodes 1a are conductive whilst the diodes 1, 2 are non-conductive. The pulse generation circuit also serves for controlling the motor when it drives the vehicle, Specifications 950,734 and 963,648 are referred to.
