Abstract: A control system includes a variable displacement hydraulic pump, the pump having an inlet for receiving fluid, an outlet for discharging fluid under pressure, and a pump displacement input, a hydraulic motor having an inlet and an outlet, a fluid circuit including a supply conduit for conducting fluid discharged by the pump to the motor and a return conduit for returning fluid discharged by the motor to the pump, a pump displacement control cooperating with the pump displacement input in order to vary a displacement of the pump, a control circuit in communication with the pump displacement control for controlling the pump output such that the motor is driven at a constant rotational speed, and a system controller in communication with the control circuit and a remote location to transmit and receive information to and from the remote location.

Abstract: An illustrative example motor control device includes a printed circuit board including electronics for motor control. At least one connector is associated with the electronics. The connector is configured for communicating at least one of control signals or power to a motor. A housing includes a first portion configured to receive the printed circuit board and cover over a first side of the printed circuit board. A second portion of the housing is configured to provide access to the at least one connector from outside of the housing. The second portion of the housing inhibits exposure of the printed circuit board to outside contaminants. A third portion of the housing is configured to cover over a second side of the printed circuit board. At least one heat transfer element on at least one of the housing or the printed circuit board facilitates heat transfer from the printed circuit board to the housing.
