Abstract
An automation assembly is adapted to be connected to a door system of a motor vehicle. The automation assembly is modular and includes a frame that is fixedly secured to the motor vehicle. A motor is fixedly secured to the frame and adapted to receive power. The motor converts the power into a rotational output force. The motor includes a non-ferrous core. A set of pulleys and rollers are fixedly secured to the frame at predetermined positions to direct the path of a continuous belt. The continuous belt is fixedly secured to the door system such that the motor moves the continuous belt and the door system bidirectionally between an open position and a closed position. Sensors are used to determine the position of the door, the speed thereof and whether the door is being moved manually.

6. A coreless motor comprising:
-
a disk having a hollow center and defining a periphery, said disk rotatable about an axis;
a magnetized member extending coaxially with said axis of said disk;
an electrical conductor being wound about said periphery of said disk; and
at least two conductors connecting said electrical conductor to an electrical current such that the electrical current passing through said electrical conductor moves said disk with respect to said magnetized member.

8. An automation assembly adapted to be connected to a door system of a motor vehicle, the door system having a door and a track for movement of the door system therealong, said automation assembly comprising:
-
a frame slideably engaged with the track of the door system;
a motor fixedly secured to said frame and adapted to receive power and to convert the power into a rotational output force;
a set of rollers fixedly secured to said frame at predetermined positions therealong; and
a belt extending between a first end and a second end, each of said first and second ends being secured to the motor vehicle, wherein said rotational output force generated by said motor moves said frame and the door assembly along the track between an open position and a closed position. - View Dependent Claims (9)
