KONE AMD D15 Right Door Motor KM903375G04

KONE AMD D15 Right Door Motor KM903375G04 is a complete door motor assembly used in KONE elevator car door operator systems.

This motor is mainly associated with the KONE AMD D15 door system. It is used to drive the elevator car door opening and closing movement through the door operator mechanism, gear structure, coupler connection, and control wiring.

It should not be treated as a traction motor or a general elevator drive motor. KM903375G04 belongs to the door machine area, where the motor works together with the door controller, belt, pulley, coupler, hanger rollers, door track, door vane, and door protection device.

The related numbers are useful for search coverage and inquiry confirmation, but they should not be used as automatic replacement approval. The correct motor must be confirmed by the old motor label, door system type, motor direction, coupler structure, connector layout, and installation position.

Built for KONE AMD D15 Door Operation

KM903375G04 is not just a small replacement motor. It is part of the door operator drive assembly.

In a KONE AMD D15 door system, the door motor affects how smoothly the car door starts, moves, slows down, and completes opening or closing. If the motor does not match the original door operator, the elevator may show unstable door movement, abnormal noise, poor door speed control, or repeated reopening after installation.

That is why this product should be selected by the exact KONE motor reference, not only by appearance.

Right-Side Version Should Be Confirmed First

KM903375G04 is commonly used as a right-side or right-opening door motor reference.

This is one of the most important confirmation points for this model. A similar KONE door motor may have a different direction, cable outlet position, coupler side, or mounting structure. If the direction does not match the old motor, the new motor may not fit the original door operator correctly.

Before quotation, buyers should confirm:

• KM903375G04 marking on the old motor
• right-side or right-opening installation
• AMD D15 door operator reference if available
• coupler side and coupler structure
• cable connector and wiring direction
• mounting bracket position
• full old motor photos
• complete door operator photo

If the old motor shows KM903375G03, it should be checked separately because KM903375G03 is commonly searched as the left-side version in the same motor group.

Why It Should Not Be Mixed With Other KONE Door Motors

KONE door motors may look similar from the outside, but different models can belong to different door operator systems.

KM903375G04 is more suitable for a KONE AMD D15 right door motor page. It should not be mixed with other KONE door motor models such as KM601370G04, KM602748G04, KM602748G03, or KM89717G06.

For example, KM601370G04 is more closely associated with AMD D2 / AMDR2 right door motor applications. KM89717G06 is usually searched as a KONE D1 geared door motor. These motors may all be used in KONE door systems, but their door system generation, coupler arrangement, mounting direction, and connector structure may be different.

For a correct replacement, the old motor label should always be the first reference.

When This Motor Is Usually Checked

Maintenance teams may inspect the door motor when the elevator door has problems such as:

• door motor not running
• door opening failure
• door closing failure
• unstable door movement
• abnormal motor noise
• door movement hesitation
• repeated reopening
• door operator fault alarm
• coupler or gear response problem

However, these symptoms are not always caused by the motor itself.

The door controller, belt tension, pulley, hanger rollers, door track, door vane, light curtain, connector terminals, and door operator wiring should also be checked before confirming the motor fault.

Photos Needed Before Supply

For overseas buyers, clear old-part photos are the fastest way to confirm this motor.

Recommended photos include:

• old KM903375G04 motor label
• full motor body
• cable connector
• coupler side
• mounting bracket
• door operator installation position
• complete door machine system
• fault description from the maintenance technician

This helps confirm whether the required replacement is KM903375G04 or another KONE AMD door motor version.

For urgent repair projects, please do not rely only on the written model number. A clear label photo and door operator photo can greatly reduce wrong supply risk.
