POWER TRANSMISSION Abstract of the Disclosure A speed controller for a rotary pump and motor hydraulic power transmission comprises a pair of pulse generators, one driven at a reference speed and the other proportionally to motor speed. An algebraic summing cir- cuit connects the two pulse generators to the displace- ment regulator of the hydraulic pump. Error signals pro- duced by the changes in phase of the pulse generators adjust the pump displacement to maintain the motor speed in step with the reference speed. i.
