The invention discloses an improved motor belt pulley for an elevator door machine. The improved motor belt pulley is characterized by comprising a belt pulley body, an outer wheel plate and an innerwheel plate, wherein the outer wheel plate and the inner wheel plate are respectively and rigidly connected with the belt pulley body, the center of the belt pulley body is provided with an inner conical hole, wedged wheel teeth are evenly machined on the outer circumference face of the belt pulley body, the small end of the inner conical hole is adjacent to one end of the outer wheel plate, and abolt through hole is machined in the center of the outer wheel plate. The conical fit coaxiality is high in precision, compactness is good, clearance or interference is adjustable, torque can be transmitted by friction force, and torque transmission is more stable and reliable.
