Abstract
A control apparatus for controlling a polyphase induction motor, comprising, in combination: a polyphase alternating current power source, a master electric valve controllable by firing circuit, connected to each of a plurality of phases of said source of feeding, between said source and said polyphase induction motor, a single-phase transformer including a primary winding connected through said source and a secondary winding having a central tap connected to one of the phases of said induction motor, a pair of electric valves controllable by a control trip circuit, connected to both ends of said secondary winding of the transformer, with the same polarity, respectively, and having respective output terminals connected to each other and to another phase of said induction motor, circuits of ignition of motor connected to said electric valves pr incipales and said electric control valves, to control the firing angles of the associated electric valves respectively, a tachometer generator operatively coupled to sense the speed of said motor, standard generator means operatively connected to generate a speed instruction pattern for said motor, distribution amplifier means coupled to said tachometer generator and said standard generator means to detect a difference between an output from said tachometer generator and an output from said standard generator means and to produce an output dependent on the detected difference, and coupled operatively to said ignition circuits to apply its output to said ignition circuits for said main electric valves when said standard generator means have a higher output than said tachometric generator and to apply said output to said circuits. Ignition values for said electric control valves when said standard generator means have an output lower than that of said tachometer generator, whereby said induction motor is controlled in accordance with the output from said standard generator means and continuously changing a voltage applied to said motor.
