Abstract: A battery-powered thyristor-controlled lift truck traction motor control system includes simple and economical means for providing plugging torque in a continuous or proportional manner. A dual-motor drive system disclosed allows series motors to be operated in parallel from a single thyristor control system during both acceleration and plugging conditions, and allows the two motors to be operated at widely different speeds without large currents circulating between them.
