Abstract
196,068. Tester, W. Andrews-, and Thompson, S. Jan. 12, 1922. Drawings to Specification. Systems for azternating-current motors only; safety arrangements.-In order to protect polyphase motors during switching-on or switching off, resistance coils or inductance coils or a combination of both are connected temporarily or permanently across the motor stator terminals, without disturbing the phase connections of the machine.
