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.
