US Patent 10441844 Cooling systems and methods for exercise equipment

An exercise machine may include a deck, a motor housing incorporated into the deck, a lift motor located in the motor housing, and a cooling mechanism that cools the lift motor when the cooling mechanism is activated. An airflow pathway may be defined to direct air from the cooling mechanism to a location above the motor housing and on to a user of the exercise machine. The exercise machine may be configured such that upon beginning operation of the machine, substantially all of the airflow exhausts to the location above the motor housing. A mechanism may be provided to selectively alter a characteristic of the airflow after the exercise machine has begun operation.
