Abstract
1,130,660. Control of A.C. motors. DANFOSS A.S. 16 Nov., 1966 [7 Dec., 1965], No. 51292/66. Heading H2J. [Also in Division H1] In a thermal bi-metal switch having contacts 4, 5, Fig. 1, mounted on the bi-metal through which the current to be cut off is passed to heat the bi-metal and open the contacts 4, 5, the contacts are maintained open by the passage of current through a resistive film 8 on an adhesive insulating strip 9 attached to the bi-metal and electrically connected across the open contacts. The switch may be adjusted by a screw (not shown) engaging one of the bimetallic elements. The film 8 may be of colloidal graphite mixed with epoxy resin and is electrically connected to the bi-metal at points 13, 14 of colloidal silver mixed with the epoxy resin. The conductivity of the insulating strip 9 may be increased at the intermediate connecting region 12 by a short-circuiting metal layer. A further insulating or reflecting layer may be attached to the film 8 to reduce heat losses. The switch may be used in series with an auxiliary winding for starting a single-phase asynchronous A.C. motor.
