Abstract

1,246,088. Electromagnetic switches; electromagnets. SEVCON ENG. Ltd. 26 Sept., 1968 [18 Oct., 1967], No. 47349/67. Headings H1N and H1P. [Also in Divisions H2 and H3] The coil of an electromagnet of a relay, contactor or of a motor field magnet has short circuited turns linked therewith and is in series with a thyristor. The shorted winding may be an annular end plate of the coil support or turns of the coil itself.
