Abstract: A permanent magnetic brushless motor with a length adjustable air gap comprises: a body; a stator secured to one end of the body; a spindle pivotally installed to the body; a part of the spindle protruding from the body; a rotor being axially movable with respect to the spindle by using a sliding unit; the rotor being pivoted in the body and an air gap being formed between the rotor and the stator; a length of the air gap being adjustable; at least one connecting unit two ends of which are connected to the rotor and the spindle; the orientation of the connecting unit being changeable with the rotation angle between the rotor and the spindle; and an elastic unit capable of pushing the rotor to move away from the stator so that the connecting unit moves to a straight state. In the motor, the adjustment of the air gap is automatically performed during the operation of the motor without needing any manual action.

Abstract: In one embodiment, an exercise treadmill includes a tread belt for permitting a user to run or walk thereon, a motor, a wheel and belt assembly for operatively connecting one end of a motor shaft to the tread belt, a sensor proximate the shaft, a controller, and a control panel. The sensor senses a speed change of the shaft in response to an impact on the moving tread belt. In response to the sensing, the controller instructs the motor to increase shaft speed in substantially real time. A user can press a vibration key on the control panel to perform at least one of changing amplitude of a sinusoid and adding same to the shaft speed, changing frequency of the sinusoid and adding same to the shaft speed, and changing the shaft speed via the controller and the motor, thereby vibrating the tread belt.

Abstract: An exercise treadmill includes a tread belt wrapped around front and rear rolls, a motor, a frame, a control panel, a sensor electrically connected to the motor for sensing a rotation of its driving shaft and generating a sense signal if sensing the rotation, and a controller electrically interconnected the sensor and the control panel for receiving the sense signal and generating and sensing a control signal to the motor. The motor may either stop the rotation of the driving shaft for maintaining the tread mill motionless in response to the user's foot impact thereon less than or equal to a predetermined reverse force or oppose a movement of the tread belt in response to the impact larger than the reverse force. Moreover, the tread belt either maintains at its current position or returns to its original position in response to stopping exercise.
