REPLACEMENT · MAINTENANCE · B2B MATCHING

Replace a rolling shutter motor from recorded evidence, not one label.

A useful replacement inquiry identifies the installed motor, door, shaft or drum, drive, electrical supply, controls, operating use and required package. This checklist helps maintenance teams and distributors gather those facts before requesting a match.

Rolling shutter motor and chain-drive components for replacement identification

SIX EVIDENCE GROUPS

Record the installed system before selecting a replacement.

  1. 01
    Existing motor evidence

    Photograph the complete nameplate and record the manufacturer, model, electrical rating, output information and every readable identifier.

  2. 02
    Door and curtain data

    Record the opening width and height, curtain material, estimated mass where known, installation position and any recent change to the door.

  3. 03
    Shaft and drive arrangement

    Photograph the shaft or drum, roller diameter, sprocket, chain and mounting arrangement. Record the required lifting height.

  4. 04
    Electrical supply

    Confirm the measured site voltage, single-phase or three-phase supply and exact frequency with a qualified electrician.

  5. 05
    Controls and safety devices

    Record the controller, receiver, wall control, remote, limit system, photocells and other connected devices. Similar appearance does not prove compatibility.

  6. 06
    Operating use and package

    State expected daily cycles, indoor or exposed use, quantity, destination and whether the quotation must include controls, brackets, chain-drive parts or other accessories.

Replacement questions, answered directly.

Can I replace a rolling shutter motor by matching only the kg rating?

No. Treat the published kg.f or lifting label only as a starting reference. Also check torque, speed, roller diameter, chain, lifting height, electrical supply, controller and the actual door mechanism.

Is a photograph of the old motor enough?

Usually not. A complete nameplate photograph helps identify the installed unit, but the door, shaft or drum, drive, electrical supply, controls, operating use and required package still need to be checked.

Will a similar-looking remote work with the replacement motor?

Not necessarily. Confirm the receiver or controller model, radio frequency, coding or pairing system and connector details. Housing shape and button count do not establish compatibility.

Should I order the same single-phase or three-phase type as the old motor?

Do not decide from appearance. A qualified electrician should confirm the site supply and the replacement specification should be checked against the actual installation and local requirements.

What should a replacement quotation list?

Ask for the exact motor model, model-specific parameters, electrical configuration, written packing list, applicable documents, MOQ, order-preparation time, warranty and shipping scope.

What can YERQI check for a B2B replacement inquiry?

YERQI can compare the supplied door, drive, electrical and control details with its verified motor range and identify missing inputs. Final suitability, package contents and commercial terms remain quotation-specific.
