Abstract: The apparatus has a speed detector (15, 13, 12) for detecting the speed V a  of an induction motor 14, speed command means for producing a command speed V CMD , and an error amplifier 1 for amplifying a difference between the detected motor speed V a  and the command speed V CMD . The motor 14 is driven by controlling the amplitude of the primary current as to vary the amplitude of the secondary current in accordance with the difference between the detected and command speeds. 
     A two-phase sinusoidal wave generating circuit 11 generates two sinusoidal signals (I m cosϕ, I m sinϕ) displaced in phase from one another by π/2 and whose amplitudes (I m ) conform to the output E r  of the error amplifier 1. A primary load current arithmetic circuit 33 computes a primary load current by employing the output E r  of the error amplifier 1 and the output of the two-phase sinusoidal wave generating circuit 11, and a primary current arithmetic circuit 34 computes a two-phase primary current command (I 1a , I 1b ) by adding the primary load current to the output of the circuit 11, which output serves as an excitation current. The induction motor 14 is driven by the primary current command having an excitation current component and a primary load current component the amplitudes of which vary in accordance with the difference between the rotational speed of the induction motor and the command speed.

Abstract: A vector generator comprises X and Y digital-to-analogue converters (65, 66) providing X and Y deflection voltages to a cathode ray tube display, and X and Y digital accumulators (50, 51) provide respective inputs to the X and Y digitals-to-analogue converters. The word lenghts of the accumulators (50, 51) are wider than those of the digital-to-analogue converters (64, 65) and the digital-to-analogue converters derive their inputs from the most significant digits of the accumulators. X rate and Y rate signals proportional to the sine and cosine of the vector angle are applied as inputs to the respective accumulators (50, 51) which accumulate the rate signals with the present contents of the accumulators so as to generate linearly changing X and Y deflection signals. The vector angle is adjusted by changing the ratio of the sine to cosine inputs to the accumulators, and the vector speed is controlled by increasing and decreasing the sine and cosine signals but maintaining the ratio there between the same.
