Abstract
A motorized pulley mounted on a stationary shaft to drive a conveyor belt. The motorized pulley is constructed of an axial-flux motor in a housing connected to the motor's rotor. A driver including a drive ring has a drive surface mounted to the periphery of the housing to rotate with the rotor and the housing and drive a conveyor belt. The motor's stator is affixed to the shaft axially offset from the rotor.
Claims21
A motorized pulley comprising:
- an axial-flux motor having a rotor rotatable about an axis of rotation and a stator axially offset from the rotor across a gap between the stator and a side of the rotor;
- wherein the stator includes an array of coils producing an axially directed magnetic flux wave interacting with the rotor and causing the rotor to rotate;
- a driver for engaging a belt, wherein the driver is coupled to the rotor to rotate about the axis of rotation with the rotor.
A belt drive system comprising:
- a stationary shaft defining an axis along its length;
- and
- a motorized pulley including:
- an axial-flux motor mounted on the stationary shaft and having a rotor rotatable about the axis and a stator affixed to the stationary shaft and axially offset from the rotor across a gap between the stator and a side of the rotor;
- wherein the stator includes an array of coils producing an axially directed magnetic flux wave interacting with the rotor and causing the rotor to rotate;
- a driver for engaging a belt, wherein the driver is coaxial with and coupled to the rotor to rotate about the axis with the rotor.
