Abstract
A roller system has a frame, a plurality of rollers (supported by the frame) forming a roller plane, and an external rotor motor (“motor”) spaced from the roller plane. As an external rotor motor, the motor has a stator and an external rotor radially outward of the stator to substantially circumscribe the stator. To kinetically couple the motor with the rollers, the system also has a transmission coupling coupled with the external rotor and at least one of the rollers. The transmission coupling and external rotor are configured so that rotation of the external rotor causes the at least one roller to rotate in response to a torque received through the transmission coupling.
Claims34
A roller system comprising:
- a frame;
- a plurality of rollers supported by the frame, each of the plurality of rollers having a roller shaft, the plurality of roller shafts forming a roller shaft plane;
- an external rotor motor (“motor”) having an internal stator and an external rotor, the external rotor being radially outward of the stator to substantially circumscribe the stator, the motor also having a motor shaft spaced from the roller shaft plane;
- and
- a transmission coupling coupled with the external rotor and at least one of the rollers, the transmission coupling and external rotor configured so that rotation of the external rotor causes the at least one roller to rotate in response to a torque received through the transmission coupling.
A roller system comprising:
- a frame having a first frame portion spaced from a second frame portion;
- a plurality of rollers rotatably coupled between the first frame portion and the second frame portion, the plurality of rollers forming a roller plane;
- a gearless DC motor (“motor”) spaced from the roller plane and positioned between the first frame portion and the second frame portion, the motor having an internal stator and an external rotor, the external rotor being radially outward of the stator;
- and
- a transmission coupling coupled with the external rotor and at least one of the plurality of rollers, rotation of the external rotor causing rotation of the at least one roller.
A roller system comprising:
- a frame;
- a plurality of rollers supported by the frame, the plurality of rollers forming a roller plane;
- and
- means for controlling rotation of the plurality of rollers, the controlling means being spaced from the roller plane,
- the controlling means comprising internal stator means and external rotor means and means for transmitting mechanical energy from the external rotor means to at least one of the plurality of rollers,
- the transmitting means and external rotor means configured so that rotation of the external rotor means causes the at least one roller to rotate in response to a force received through the transmitting means.
