Abstract
The present invention relates to an external rotor motor for a treadmill. A supporting shaft extends between mounting brackets. A coil stator is installed in the middle of the supporting shaft. Rotation seats are fitted to both sides of the coil stator by means of bearing, respectively. A belt wheel is arranged at one side of the rotation seat. An external rotor is arranged around the coil stator by means of both rotation seats. An annular thickened section is disposed onto the round housing of the external rotor, thereby forming a flywheel type device. Accordingly, processing and material cost of the present invention can be reduced and the treatment of the dynamic balance is performed only one time so that the required precision is easily achieved.
Claims6
An external rotor motor for a treadmill comprising:
- a supporting shaft extending between mounting brackets;
- a coil stator installed in the middle of said supporting shaft;
- a pair of rotation seats rotatably fitted to said supporting shaft on opposing sides of said coil stator by respective bearings;
- a belt wheel coupled to one side of one of said rotation seats;
- an external rotor having a round housing disposed around said coil stator and coupled to said rotation seats for rotation therewith relative to said coil stator;
- and
- an annular thickened section mounted onto said round housing of said external rotor and centrally disposed between opposing ends thereof, to thereby form a flywheel for said external rotor.
