This utilised a double eccentric system, as employed on variable stroke electrical power presses, to regulate the stroke length of A 3 cylinder radial motor.[2] Afterwards, the swashplate engine by having an adjustable swashplate angle would develop into a well-liked way to produce variable stroke hydraulic motors.

Most electric motors call for some form of stage-down controller placed involving the motor plus the pump. This is due to an A/C motor, the commonest electrical design, only generates a set degree of electrical power.
