Abstract
A treadmill includes a frame; a running belt configured to rotate relative to the frame; and a motor coupled to the running belt. The motor is operable in a plurality of user controlled operating modes. In a first operating mode, a user of the treadmill provides a force of rotation to the running belt. In a second operating mode, the motor is adapted to resist rotation of the running belt. In a third operating mode, the motor is adapted to provide a force of rotation to the running belt at a desired speed.
Claims20
A treadmill, comprising:
- a frame;
- a running belt configured to rotate relative to the frame;
- and
- a motor coupled to the running belt, the motor operable in a plurality of user controlled operating modes such that:
- in a first operating mode, a holding torque of the motor is disabled to allow the running belt to substantially freely rotate so that a user of the treadmill provides a force of rotation to the running belt;
- in a second operating mode, the motor is adapted to resist rotation of the running belt;
- and
- in a third operating mode, the motor is adapted to provide a force of rotation to the running belt to cause the running belt to rotate at a desired speed.
5 more elements
A treadmill, comprising:
- a running belt;
- and
- a motor coupled to the running belt, the motor operable in a plurality of operating modes such that:
- in a first operating mode, the motor applies a desired resistance to resist rotation of the running belt;
- in a second operating mode, the motor rotates the running belt at a desired speed;
- and
- in a third operating mode, a holding torque of the motor is disabled to allow the running belt to substantially freely rotate so that a user of the treadmill drives rotation of the running belt.
4 more elements
A treadmill, comprising:
- a frame;
- a display device coupled to the frame and configured to provide information regarding a use of the treadmill;
- a running belt coupled to the frame and adapted to rotate relative to the frame;
- a handrail coupled to the frame, the handrail having at least one input device configured to control operation of a motor;
- and
- the motor operably coupled to the running belt, the motor operable in a plurality of operating modes such that:
- in a first operating mode, the motor drives rotation of the running belt at a selected speed;
- in a second operating mode, a selected resistance is input and the motor applies the selected resistance to resist rotation of the running belt;
- and
- in a third operating mode, a holding torque of the motor is disabled to allow the running belt to substantially freely rotate so that a user of the treadmill drives rotation of the running belt.
