AC Fan Motor Specification Example for Off-Road Bikes: Fixed Type

This is a worked specification for ac fan motor in a fixed type 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 fixed type version exists because the duty cycle on off-road bikes is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually reorders that did not match the approved sample.

Questions buyers ask

What happens if a lot fails inspection?

The lot is re-inspected against the golden sample, and replacement pieces ship on the next available booking at our cost.

How long does sampling take?

Samples leave the factory in 10 working days, and each revision round adds about 5 days once you have seen the first piece.

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.

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.

Tell us the model, the fitment and the quantity and we will hold a production slot for you.
