Resistance regulation device for stationary exercise equipment

Abstract

A stationary exercise equipment resistance regulation device includes a stator holder, an axle, a circuit board, at least one magnetism detection element, a rotary knob, and at least one magnet. When the rotary knob is operated to rotate, a distance between a magnet and the magnetism detection element is changed so as to vary a magnetic force detected by the magnetism detection element to thereby change a magnitude of an induced voltage or generate a rotation turn signal. Based on the induced voltage or the rotation turn signal, a signal processing device identifies a resisting force level and calculates data of one of a resisting force magnitude and wattage that the resistance device applies to the stationary exercise equipment.
