Abstract

449,202. Alternating-current motors. CROYDON ENGINEERING CO., Ltd., 80, Gloucester Road, Croydon, FIRMIN, P. S., The Shanty, Wallington Green, Surrey, and PAYNE, C. F. E., 133, Alexandra Road, East Croydon. Feb. 20, 1935, No. 5455. [Class 35] In a synchronous motor of the squirrel cage type, locking of the rotor at synchronous speed is obtained, without the use of peripheral synchronizing grooves, by means of holes in the core 1 underneath the bars. As shown, the squirrel cage bars are located in slots 3, and between these slots and the axis are provided arcuate holes 2 equal in number to the number of stator poles. Some or all of the rotor laminations are formed with slots so that the holes 2 extend partly or wholly through the complete core.
