ABSTRACT:
An arrangement of electric motors which are coupled together both mechanically and electrically comprises series pass elements and current sensing devices in the power circuits of the respective motors, each current sensing device having an output voltage which is proportional to its motor current, and which is applied to a respective linear operational amplifier having an output which controls the equivalent resistance of the series pass element (and thereby the magnitude of motor current). A single reference voltage is applied to all the linear operational amplifiers, so that, for example, if the motors are similar, each will transmit the same torque regardless of any difference in its internal impedance.
