Abstract
An exercise device is described having a motor assembly (28) and an electronic control system (36) including a circuit board (40) and electronic components for controlling the exercise device and the motor power output. The main heat-generating electronic components are accumulated into a power control module (44) that is attached to one side of the circuit board. A cooling system (50) is connected to the power control module. The cooling system has a heatsink (60) and a fan (62). In one embodiment, the heatsink includes a base plate (64) that contacts the power control module and a plurality of fins (66) projecting in an array from the other side of the base plate. A fan is positioned within the circle of fins to blow cooling air thereover. The fan is preferably powered by a source independent of the motor power output.
