Prepare a clearer motor or gearbox enquiry with the rig…
A useful quotation needs a clearly defined product specification. A request such as “one motor” or “a gearbox for a conveyor” is a starting point, but it does not provide enough information to identify a suitable configuration.
Preparing a few key details helps reduce clarification rounds and makes competing quotations easier to compare.

1.Explain Whether the Project Is New or a Replacement
For new equipment, describe the machine and provide its required operating conditions. Include available drawings or a technical specification.
For a replacement, provide the existing manufacturer, full model code, and nameplate information. Explain whether the old unit performed satisfactorily or whether the replacement needs to address a different load, speed, or installation requirement.
For a replacement, provide the existing manufacturer, full model code, and nameplate information. Explain whether the old unit performed satisfactorily or whether the replacement needs to address a different load, speed, or installation requirement.
2.Provide the Essential Motor Information
For a motor enquiry, include:
| Information | What to Provide |
|---|---|
| Rated output | Required power in kW or HP |
| Electrical supply | Voltage, frequency, and phases |
| Operating speed | Required rpm or the existing rated speed |
| Mounting | Foot, flange, or another required arrangement |
| Duty | Operating hours, starts, and load changes |
| Environment | Temperature, altitude, moisture, dust, or special conditions |
| Control method | Direct supply, soft starter, or variable frequency drive |
For multi-speed motors, provide the required rating at each speed. For special environments or high-voltage applications, attach the project’s technical requirements rather than relying on a short product description.
3.Provide the Essential Gearbox Information
For a gearbox enquiry, include:
| Information | What to Provide |
|---|---|
| Drive layout | Inline, parallel-shaft, or right-angle |
| Input | Motor power, speed, and connection |
| Output | Required speed and torque |
| Ratio | Existing or required ratio, if known |
| Connections | Solid shaft, hollow shaft, flange, or other interface |
| Mounting | Installation position and available space |
| Load conditions | Starts, reversals, load peaks, and running hours |
If the required torque is unknown, describe the driven equipment and provide the load information you have. Avoid selecting a gearbox using motor power alone.
4.Attach Useful Photos and Drawings
A clear nameplate photo often provides more useful information than several distant equipment photos.
For replacement projects, include:
A readable nameplate photograph.
An overall view of the motor or gearbox.
The shaft or output connection.
The mounting feet or flange.
A dimensional drawing, if available.
Photographs show the arrangement, but they cannot reliably establish exact dimensions. Provide measured dimensions or drawings for critical interfaces.
For replacement projects, include:
A readable nameplate photograph.
An overall view of the motor or gearbox.
The shaft or output connection.
The mounting feet or flange.
A dimensional drawing, if available.
Photographs show the arrangement, but they cannot reliably establish exact dimensions. Provide measured dimensions or drawings for critical interfaces.
5.Include Quantity and Delivery Requirements
State the required quantity, delivery destination, and target delivery date. Mention whether the request is for a sample, a single replacement, or a repeat purchasing requirement.
If the project requires particular documentation, packaging, inspection, or shipping terms, include those details in the enquiry.
If the project requires particular documentation, packaging, inspection, or shipping terms, include those details in the enquiry.
6.Check What the Quotation Includes
When reviewing an offer, confirm:
The exact model and configuration.
Electrical and mechanical ratings.
Whether the price includes a motor, gearbox, adapter, or other accessories.
Applicable documentation and drawings.
Delivery terms and estimated lead time.
Warranty terms and any exclusions.
A gearbox-only quotation and a complete gearmotor quotation may look similar at first glance but cover different supply scopes.
