1. A motor module adapted to be mounted in a driving device cylinder and adapted to be connected to a reduction gearbox; the motor module comprising:
a bearing base having
a bearing base casing; an outer annular surface of the bearing base casing adapted to be securely mounted on an inner annular surface of the driving device cylinder;
a stator mounted securely to the bearing base and having
a stator casing; an outer annular surface of the stator casing adapted to be securely mounted on the inner annular surface of the driving device cylinder; an end surface of the stator casing directly connected to an end surface of the bearing base casing;
a rotor rotatably mounted in the stator, rotatably mounted through the bearing base, and adapted to be connected to the reduction gearbox;
a fixing base mounted securely with the stator and having
a fixing base casing; an outer annular surface of the fixing base casing adapted to be securely mounted on the inner annular surface of the driving device cylinder; an end surface of the fixing base casing directly connected to the other end surface, which is opposite to the bearing base casing, of the stator casing; and
a circuit board mounted in the fixing base and electrically connected to the stator;
wherein an outer diameter of the bearing base casing, an outer diameter of the stator casing, and an outer diameter of the fixing base casing are the same.
