Abstract
A fitness equipment structure with an external-rotor motor includes: a force application unit fixed on a basic frame; a motor with an external rotor rotatably provided on the basic frame and surrounding an internal stator; an encoding disk that can rotate along with the external rotor; an encoding unit for reading rotation information provided by the encoding disk; and a control unit for receiving the rotation information and controlling an electromagnetic field of the internal stator in order for the external rotor to provide rotational resistance, wherein the control unit selectively changes the intensity of the electromagnetic field in order to change the rotational resistance.
