Title: Improvements in electric control system
IPC: B66B1/08
Filed: 1926-05-17
Abstract: 268,992. Thurston, E. B. May 17, 1926. Systems for alternating-current motors; electric braking.-Alternating-current motors having two stator windings for low-speed and high-speed respectively are electrically braked by switching back from the high speed to the low speed windings, and are afterwards braked mechanically by an action which may overlap the electrical braking. Cushioning resistance is permanently included in the electrical braking circuit. The invention is described in connection with a lift operated by a two-phase induction motor on a four-wire supply. Control circuits and contactors are so arranged that, by turning the lift car-controller 53 to either side from the neutral position shown, current is successively supplied to the low-speed windings 84 and the high-speed windings 85 of the motor 77. In each stage resistance is excluded by an automatic action effected, during the low-speed stage, by a solenoid 97, and during the high-speed stage by an auxiliary induction motor 123. Resistances 90, 94 for use in the subsequent braking are left in the circuit of the low-speed windings. In full speed normal ascent the controller contact 52 would be on the right-hand extreme stud 100. When the controller is moved back to the next stud 61, the low-speed windings are reinserted in place of the high-speed windings, producing the required electrical braking effect until the rotor has slowed down to its lower synchronous speed. Further backward movement of the controller handle effects the de-energization of coils holding off the mechanical brake 73, and a speed governed switch 156, opened by a prescribed reduction in the rate of revolution, cuts-out the resistances 90, 94 to strengthen the electrical braking action.
