OTIS AT120 Door Motor FAA24350BL1 FAA24350BL2

OTIS FAA24350BL1 and FAA24350BL2 are elevator door motors used in compatible OTIS AT120 car-door operator systems.

The motor provides the mechanical drive required for opening and closing the elevator car door. It works together with the AT120 door controller, transmission mechanism, belt or linkage, and door-position feedback components.

Confirm the Installation Direction

FAA24350BL1 and FAA24350BL2 belong to the same AT120 door-motor family, but they are commonly supplied for different installation directions.

Public replacement references generally describe:

• FAA24350BL1 as the right-position version

• FAA24350BL2 as the left-position version

The installation side should still be confirmed from the original motor and complete door operator. A motor supplied for the wrong direction may not match the mounting position, output orientation, or existing transmission arrangement.

Before ordering, please provide:

• FAA24350BL1 or FAA24350BL2 marking

• complete motor nameplate

• left- or right-position installation

• motor voltage and rated data

• output shaft and gear structure

• connector and cable arrangement

• mounting-hole dimensions

• AT120 door controller model

• complete door-operator photo

• quantity required

Market specifications commonly associated with this motor include a 24V supply, approximately 203 rpm output speed, 108 Ncm torque, and a 15:1 reduction ratio. These values should be checked directly from the old motor label before final confirmation.

When the Motor Is Not the Only Cause

Replacement may be considered when the motor does not rotate, runs intermittently, produces abnormal noise, overheats, or no longer drives the door smoothly.

Before replacing the motor, technicians should also inspect:

• AT120 door controller

• motor wiring and connector

• door belt or transmission mechanism

• door track and hanger rollers

• mechanical resistance

• door-position feedback

• controller parameters

• power-supply condition

A tight door mechanism, damaged belt, incorrect controller setup, or unstable power supply may produce symptoms similar to motor failure.

Installation and door commissioning should be completed by qualified elevator technicians. Door opening, closing, reversal, speed, force, and protection functions must be checked before the elevator returns to normal service.

For buyers in Saudi Arabia, Jordan, Egypt, Iraq, UAE, Kuwait, Brazil, Colombia, Spain, and Italy, clear photos of the motor label, mounting direction, output shaft, connector, and complete AT120 door operator are recommended before shipment.

FAQ

What is the difference between FAA24350BL1 and FAA24350BL2?

They are commonly supplied as different installation-direction versions. BL1 is generally listed as the right-position motor, while BL2 is commonly listed as the left-position motor. The original installation must still be checked.

Can BL1 replace BL2 directly?

Not automatically. The mounting direction, output orientation, connector, shaft structure, and complete AT120 door-operator configuration should be compared first.

Is this the complete AT120 door operator?

No. FAA24350BL1 and FAA24350BL2 refer to the door motor. The controller, belt, transmission parts, hanger assembly, and other door components are separate.

Is the motor rated for 24V?

Public replacement specifications commonly list this AT120 motor as a 24V unit, but the voltage and complete electrical data should be confirmed from the original nameplate.

What information should I send before quotation?

Please send the old motor label, left or right installation position, connector, output shaft, mounting dimensions, AT120 controller model, and a photo of the complete door operator.
