ABSTRACT:
A hydraulic process and apparatus recover energy generated by the testing of a motor in the form of electrical energy. The process includes utilizing a hydraulic pump and an asynchronous electric generator and coupling the shaft of the motor being tested to the hydraulic pump, feeding a plurality of hydraulic motors by the pump in accordance with the feed from the hydraulic pump and coupling the hydraulic motors to the asynchronous generator so that the motors will be capable of operating both as pumps and motors. The device for recovering energy includes a hydraulic volumetric pump, an asynchronous electric generator, and a pressurized oil reservoir connected to the hydraulic pump. The motor being tested is attached to the pump. A plurality of hydraulic motors are connected in parallel with the hydraulic pump and in series with the asynchronous electric generator so that the motors can act both as pumps by feeding themselves and as motors to furnish energy to the asynchronous generator.
