ABSTRACT:
Motor driver/control apparatus employs a motor speed regulating amplifier configuration, e.g., two push-pull power amplifiers operable responsive to a motor speed-direction command input signal, and having the motor differentially connected between amplifier output ports. The amplifier(s) are supplied with an energizing potential of variable amplitude just sufficient for amplifier operation and to satisfy the then obtaining motor consumption. Accordingly, system power is effectively utilized; needless power drain avoided; and the amplifier cost and complexity is reduced since the amplifier need not dissipate inordinate source-supplied energy not required for motor actuation.
In accordance with one further aspect of the present invention, a power supply switching regulator for a motor utilized in a radar application is operated at the radar pulse repetition rate. This produces a non-interferring zero frequency beat between the power supply and radar pulse rate in the radar receiver.
