Electric Motor Speed Controller Specification Example for Passenger Cars: Touring Version
Electric Motor Speed Controller Specification Example for Passenger Cars: Touring Version
This is a worked specification for electric motor speed controller in a touring version 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 touring version version exists because the duty cycle on passenger cars is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually inconsistent hardness between lots.
Example specification
| Item | Electric Motor Speed Controller |
|---|---|
| Application | Passenger Cars |
| Version | Touring Version |

| MOQ | 200 pieces per specification |
| Sampling | 7 working days, 3 days per revision |
| Compliance | ECE R90 |
How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — PVC Coated Fabric, 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
- precision stamping
- die casting
- anodising
- cold forging
- powder coating
- sintering
Where this example applies
Programmes that run touring version most often specify this build for passenger cars. Related applications include long-haul trucks, agricultural trailers, racing teams, off-road bikes, delivery vans.
Checks before packing
- Dimensional report against the approved drawing.
- AQL 2.5 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 ECE R90-compliant build instead of a fresh interpretation.
What is the minimum order quantity?
The standard MOQ is 200 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.
Can you match an existing sample?
Send a sample and we will reverse-engineer the specification, then produce a counter sample for approval before any bulk starts.
How long does sampling take?
Samples leave the factory in 7 working days, and each revision round adds about 3 days once you have seen the first piece.
Send the part number, the annual volume and the target market, and we will come back with a specification and a sampling plan.
