The electric motor that drives the door opening and closing mechanism, controlling speed, torque, and position of elevator doors.
Full Definition
The door operator motor is a critical component of the automatic door system, typically a variable-speed DC or AC motor coupled with an encoder for precise positioning. It drives a linkage or belt mechanism to move the car door and coupled landing door panels simultaneously. Motor parameters — acceleration, deceleration, holding torque, and reversal sensitivity — are programmed in the door controller to meet safety standard requirements. The motor must provide sufficient force to close doors without creating a hazard while being sensitive enough to reverse on contact with an obstruction. Regular testing per EN 81-20 verifies closing force limits.
