Motor Housings & End Covers
Define mounting datums, machined bores, end-cover interfaces and sealing faces. Include mating references, critical dimensions and the inspection condition for the assembled interfaces.
Engineering applications
New Energy Vehicle Components
Motor housings, power control enclosures and charging equipment components.
Motor · Power control · Charging
Components for Drive, Power & Charging Systems
Identify the housing’s role and mating interfaces within the vehicle or charging equipment. Review mounting datums, machined surfaces, sealing and final delivery requirements together.
Power Control & Onboard Supply Housings
Provide enclosure geometry, mounting features, contact surfaces and assembly references. Mark protected areas and the dimensions that must be accepted after machining and finishing.
Charging Equipment Housings
Define installation interfaces, covers, sealing surfaces and final finish. Include operating conditions, handling protection and any specified tests for the housing.
Datums · Sealing · Cleanliness · Traceability
Coordinate Interfaces and Acceptance
Include critical features, test methods and required records with the drawing. Cleaning, testing, traceability and customer approval scope are confirmed for the project before order acceptance.
| Requirement area | Define for review | Agree for acceptance |
|---|---|---|
| Mounting & machined interfaces | Datum scheme, bores, mounting faces, hole patterns and mating references. | Critical dimensions, inspection setup and the final condition used to check fit and alignment. |
| Sealing & specified tests | Sealing surfaces, cover interfaces and any required leak or pressure test, including method and conditions. | Test scope, sampling frequency, acceptance criteria and the records required for the component. |
| Cleanliness & surface condition | Controlled surfaces, burr limits, cleaning requirements, finish and protected areas. | Cleaning and inspection scope, surface acceptance and handling or packaging requirements. |
| Traceability & project records | Material records, part/lot identification, drawing revision and customer-specific documentation or approvals. | Identification method, required reports and the review steps for drawing, tooling or process changes. |
Geometry, quantity & delivery condition
Plan the Component Manufacturing Route
Compare material, housing geometry, demand and design maturity before selecting the route. Coordinate tooling, machining, finishing and assembly around the required delivery condition.
CNC Machining
Review prototypes and machined components against material condition, stock form, workholding and critical interfaces. Include planned design changes and quantity requirements.
Review manufacturing route →Die Casting
Review the casting alloy, housing geometry, draft and tool layout against the production demand. Identify machined interfaces, sealing faces and any additional inspection requirements.
Review manufacturing route →Casting + Finish Machining
Connect cast housings to machined datums, bores, threads and sealing surfaces. Agree locating strategy, allowances, deburring, cleaning and final inspection requirements.
Review manufacturing route →Finishing, inspection & delivery requirements
Surface Finishing
Define coating, masked interfaces, appearance criteria and the dimensions inspected after treatment.
Review requirements →Quality Planning
Agree dimensional checks, specified leak or pressure tests, cleanliness records and part identification.
Review requirements →Product Assembly
Specify inserts, fasteners, fit checks, part identification and packaging against the delivery requirements.

New Energy Vehicle application notes & review sequence
Product Range
Motor housings and end covers, power control enclosures, onboard power supply housings and charging equipment housings.
Design Review
Define mounting datums, machined interfaces, sealing surfaces and assembly requirements on the drawing. Where applicable, specify leak testing, cleanliness and traceability requirements before quotation.
Manufacturing
The proposed production route may include tooling, die casting, CNC machining, surface finishing and assembly. Process selection considers the material, geometry, quantities and required delivery condition; critical features and acceptance criteria are reviewed against the drawing.
Inspection
Agree the critical dimensions, inspection method and required records before production. Specify any additional tests, including the method, sampling frequency and acceptance criteria, in the project requirements.
Project Requirements
Send your 3D model and 2D drawing, material specification, quantities, finish requirements and delivery schedule. Include assembly references and any customer-specific inspection or documentation requirements.
Before You Send the Drawing
What should accompany a motor housing drawing?
Include mounting datums, machined interfaces, end-cover and sealing references, material specification and critical dimensions. State the required inspection and delivery condition.
How should leak testing and cleanliness be specified?
Identify the applicable surfaces and test requirements. Provide the test method, conditions, sampling frequency and acceptance criteria, together with cleaning and required record specifications.
When should traceability and customer requirements be provided?
Include material records, part or lot identification, required reports and customer-specific approvals with the RFQ so scope can be confirmed before order acceptance.
