Abstract
970,706. Control of A.C. motors. ELECTRIC & MUSICAL INDUSTRIES Ltd. Jan. 4, 1961 [Jan. 14, 1960], No. 1381/60. Heading H2J. The torque produced by two windings 1, 2 of an induction motor M driving a magnetic tape reel is controlled in magnitude and direction by pressure of a member 5 in a carbon pile potentiometer connected across both windings and a phase-splitting capacitor 3, no torque being produced when the pressure is uniform on both halves. The pressure is exerted by a tape tension sensing arm so that the reel is either driven or is dynamically braked to maintain the tension constant.
