KONE Tachogenerator RE.0444L1B0.06CA KM276027

KONE Tachogenerator RE.0444L1B0.06CA is a speed-feedback component used in compatible KONE elevator drive or motor systems.

The unit is commonly identified by the model RE.0444L1B0.06CA together with the KONE reference KM276027. Some replacement-part listings also associate it with KM811491G01. It may be described as a DC tachogenerator, elevator tachometer, speed generator, or motor-feedback device.

The Label Is Only the First Check

A tachogenerator converts mechanical rotation into an electrical feedback signal. For replacement work, the correct model must match the original mechanical installation and electrical connection.

Before ordering, please provide:

• RE.0444L1B0.06CA model marking

• KM276027 or KM811491G01 reference, if visible

• complete product label photo

• shaft and coupling structure

• mounting-flange dimensions

• fixing-hole positions

• cable length and wire quantity

• connector or terminal arrangement

• matched motor or drive information

• installed-position photo

• quantity required

Two tachogenerators may have a similar housing but different shaft dimensions, mounting structures, output characteristics, cable definitions, or rotation requirements. The complete old unit should therefore be compared rather than relying only on the word “tachogenerator.”

Check the Mechanical Drive as Well

When the feedback signal becomes unstable, the tachogenerator itself is not always the only possible cause.

Technicians should also inspect:

• coupling or friction wheel condition

• shaft alignment

• mounting pressure

• bearings

• cable and connector condition

• grounding

• motor rotation

• drive feedback circuit

A loose coupling, worn friction wheel, damaged cable, or incorrect alignment may produce symptoms similar to a failed tachogenerator.

Replacement may be considered when the unit has no output, unstable speed feedback, excessive bearing noise, visible shaft damage, intermittent signal loss, or drive faults linked to the feedback circuit. Electrical testing and final commissioning should be completed by qualified elevator technicians.

For buyers in Saudi Arabia, Jordan, Egypt, Iraq, UAE, Kuwait, Brazil, Colombia, Spain, and Italy, clear photos of the original label, shaft, connector, and installed position are recommended before shipment.

FAQ

Is RE.0444L1B0.06CA the same as KM276027?

They are commonly listed together for the same KONE tachogenerator product. The model label and KONE reference should still be confirmed from the old unit.

Is this an encoder?

Many suppliers describe it as an encoder or tachometer, but the more precise market description is a tachogenerator or speed-feedback generator. It should not automatically be treated as interchangeable with a digital pulse encoder.

Can it be ordered only by the model number?

The model number is important, but the shaft, mounting flange, cable, connector, motor application, and installed position should also be checked.

Should the tachogenerator wheel be inspected?

Yes. If the installation uses a friction or tachogenerator wheel, its diameter, surface condition, contact pressure, and alignment should be inspected together with the generator.

What photos should I send before quotation?

Please send the complete label, front and rear views, shaft or coupling, connector, cable, mounting flange, and the motor or installation position.
