Abstract
A treadmill can include a deck, a first pulley incorporated into the deck, a second pulley incorporated into the deck, a tread belt surrounding the first pulley and the second pulley, a drive motor in mechanical communication with at least one of the first pulley and the second pulley to move the tread belt in a first direction, a runaway load component in electrical communication with the drive motor. The runaway load component draws electrical power generated by the drive motor during a runaway motor condition.

A treadmill, comprising:
- a deck;
- a first pulley incorporated into the deck;
- a second pulley incorporated into the deck;
- a tread belt surrounding the first pulley and the second pulley;
- a drive motor in mechanical communication with at least one of the first pulley and the second pulley to move the tread belt in a first direction;

A treadmill, comprising:
- a deck;
- a first pulley incorporated into the deck;
- a second pulley incorporated into the deck;
- a tread belt surrounding the first pulley and the second pulley;
- a housing incorporated into the deck;
- a drive motor disposed within the housing and in mechanical communication with at least one of the first pulley and the second pulley to move the tread belt in a first direction;
- a dump resistor in electrical communication with the drive motor;
- a cooling fan disposed within the housing and in electrical communication with the drive motor;
- wherein the cooling fan draws electrical power generated by the drive motor during a runaway motor condition;
- wherein the dump resistor also draws power from the drive motor during the runaway motor condition;
- wherein the runaway motor condition exists when a user moves the tread belt at a force that is greater than that which is outputted with the drive motor when an incline angle of the deck exceeds a threshold angle.
