Electric Car Motor Specification Example for Boat Trailers: Vented Design
Electric Car Motor Specification Example for Boat Trailers: Vented Design
This is a worked specification for electric car motor in a vented design programme. It is the document we would send a buyer who asks what exactly they are getting: the material, the dimensions that are actually controlled, the finish, and the checks that happen before anything is packed.
The vented design version exists because the duty cycle on boat trailers is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually documentation that arrived after the container shipped.
Example specification
| Item | Electric Car Motor |
|---|---|
| Application | Boat Trailers |
| Version | Vented Design |
| Base material | EPDM Rubber |
| Controlled dimensions | 6 key dimensions, recorded per lot |

| Finish | anodised |
| MOQ | 500 pieces per specification |
| Sampling | 14 working days, 3 days per revision |
| Compliance | E-mark |
How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — EPDM Rubber, in this example.
- List the dimensions that are actually controlled and the tolerance on each.
- Name the finish and what it has to survive.
- State the inspection level and who pays when a lot fails.
Processes involved
- electroplating
- shot blasting
- surface grinding
- rubber vulcanisation
- gravity casting
- CNC machining
Where this example applies
Programmes that run vented design most often specify this build for boat trailers. Related applications include boat trailers, aftermarket retail, passenger cars, scooter fleets, city buses.
Checks before packing
- Dimensional report against the approved drawing.
- AQL 4.0 sampling on the finished lot.
- Finish inspection under agreed lighting.
- Carton drop test on the first lot of a new packing specification.
Questions buyers ask
Can the specification be held on file?
Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the E-mark-compliant build instead of a fresh interpretation.
How is packing specified?
Individual packing, inner box quantity and carton marking are confirmed at quotation stage so the cartons arrive ready for your warehouse.
What is the minimum order quantity?
The standard MOQ is 500 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 500 pieces per line.
Send the specification you are working to and we will confirm what we can match, what we would change and why.
