Technical review
Custom Motor Housing RFQ Parameters
Custom means the values are established by the released drawing. These fields define what must be reviewed before GX confirms feasibility, price, tooling and acceptance.
| Parameter | Reference value / range | Release condition |
|---|---|---|
| Digital definition | STEP / IGES / Parasolid + controlled 2D PDF | Include revision, datums, GD&T and critical-characteristic marks |
| Process / material routes | CNC, extrusion, HPDC/LPDC/gravity/sand casting, deep drawing; 6061/6063/ADC12/A356, HT250, SPCC/SUS304 examples | Route and grade selected after DFM; not every route is treated as in-house |
| Fit classes | H6–H9 / project-defined | Stator, bearing, cover, seal and mounting interfaces |
| Critical roughness | Ra 0.8–3.2 μm typical review band | Function and process determine the released value |
| Geometric control | 0.02–0.05 mm OD ≤100 / 0.05–0.10 mm OD 100–300 / 0.10–0.15 mm OD >300 | Coaxiality, runout, flatness and perpendicularity are assigned by size and function |
| Cooling / pressure | Natural, forced-air or liquid; leak test 1.5–2× maximum working pressure | Fluid, temperature, flow, pressure, hold time and allowable leak rate required |
| Validation | FAI, CMM, PPAP, leakage, coating, cleanliness by agreement | Documents and sampling plan fixed at quotation |
Final values become supply commitments only when written into the released drawing, approved specification, quotation and acceptance plan.

Product and supply scope
What Is a Custom Motor Housing Project?
A custom motor housing project converts the motor's mechanical, thermal and environmental requirements into a manufacturable enclosure with controlled stator, bearing, end-cover, mounting, connector and cooling interfaces. The best process depends on the drawing and production plan rather than the product name alone.
GX manages drawing review, process selection, supplier coordination, sample approval, key-characteristic inspection and export delivery through the GX-Managed Manufacturing Network. Each quotation states which forming, machining, treatment, assembly and validation operations are included.
Project route
Move from Drawing Review to a Controlled Production Baseline
The same revision, datum system and acceptance plan must follow the housing from prototype through tooling and recurring production.
Input Review
Review CAD, 2D drawing, mating parts, operating limits, volume and validation.
DFM and Route
Compare CNC, extrusion, casting, deep drawing or fabrication against the requirement.
Sample Build
Produce prototypes or tool samples and record deviations against the released drawing.
Interface Validation
Confirm stator, covers, bearings, mounts, seals, cooling and connector package.
Process Approval
Freeze tooling, fixtures, control plan, sample, reports and packaging standard.
Recurring Supply
Control revision, material lot, critical dimensions, nonconformance and traceability.
Verification
Define the Evidence Before Comparing Custom Housing Quotations
A useful quotation states which characteristics are measured, by what method, at what frequency and against which released revision.
| Control item | Method / evidence | Buyer benefit |
|---|---|---|
| Material | Certificate, chemistry, hardness or project-specific tests | Confirms the approved material route |
| Critical geometry | CMM, gauges, roundness, roughness and dedicated fixtures | Controls mating and rotating interfaces |
| Sealing / cooling | Pressure, leakage and flow tests where specified | Validates the defined fluid boundary |
| Surface / cleanliness | Coating, adhesion, masking and residual contamination | Protects fits, bonding and service environment |
| Change / batch control | Revision, sample approval, inspection plan and traceable records | Keeps recurring supply aligned with approval |
Application fit
Where Custom Motor Housing Fits OEM Motor Designs
Application fit is established by the mating motor package, mounting, load, thermal path, environment and validation—not by the housing name alone.
Automotive Motor Components
Drawing-based housings for auxiliary pumps, actuators and compact drives.
Appliance and Pump Motors
Interfaces coordinated with ferrite magnets, stators, rotors and fluid conditions.
Servo and Automation
Precision flange and bore packages reviewed for dynamic and thermal requirements.
Industrial and Special Motors
IEC/NEMA-related or non-standard frames evaluated from actual project inputs.
Project control
Documented Control for Drawing-Based Custom Motor Housing Supply
GX coordinates revision, material, process, sample approval, critical-characteristic inspection and recurring records according to the project scope. Certification claims are limited to their documented company and product scope.
Revision and BOM Control
Housing material, interfaces, finish, supplied components and acceptance follow the released revision.
Sample Approval
Dimensions, interface fit, surface and project-specific tests are recorded before recurring production.
Batch Inspection
Incoming, in-process and final controls use the agreed method, fixture, sampling and limits; Cpk ≥1.33 is the reference target where critical-characteristic capability is required.
Available project evidence is confirmed at quotation and may include material records, dimensional or CMM reports, roughness, coating, leakage, cleanliness and marked-drawing results.
Buyer communication
Discuss Custom Motor Housing Projects Face to Face
GX Magnet uses industrial exhibitions and engineering discussions to connect magnetic materials, stator/rotor interfaces and drawing-based motor-component supply.
Bring the housing and mating-component drawings. The review can identify the datum chain, supply boundary, process risks and missing RFQ information before formal quotation.
Sample Review
Compare materials, housing forms, machined interfaces and surface treatments.
Engineering Discussion
Review stator fit, bearing axis, mounting, cooling, sealing and inspection.
Supplier Evaluation
Plan DFM, sample approval, evidence, change control and recurring communication.
GX Magnet
Magnetic-Material and Motor-Component Experience Since 1992
GX combines established permanent-magnet experience with drawing-defined motor-component coordination so housing interfaces can be reviewed together with the stator, rotor, magnets, end covers and operating package.
Magnetic Interface Knowledge
Ferrite magnets, multipole rings and rotor/stator component experience support air-gap, magnet-location and assembly discussions.
GX-Managed Manufacturing Network
Forming, machining, treatment and assembly responsibilities are coordinated and stated by project rather than described as universally in-house.
Drawing-Based Verification
Critical dimensions, sample records and agreed batch checks connect the quotation to recurring delivery.

FAQ
Custom Motor Housing Sourcing Questions
Clarify the drawing, interfaces, process route, operating conditions, test boundary and supplied BOM before comparing quotations.
Which files should be sent for a custom housing review?
Send a controlled 2D PDF with GD&T and a STEP, IGES or Parasolid model, plus mating-component drawings, revision status and a marked list of critical characteristics.
How does GX choose between CNC, extrusion, casting and deep drawing?
The decision uses geometry, wall sections, tolerance, material, cooling, sample timing, tooling budget and annual demand. GX documents the included route in the quotation.
Can CNC prototypes be converted directly into die-cast production?
Not automatically. Draft, wall transitions, ribs, machining stock, datum access and material behavior must be redesigned and revalidated before tooling release.
Can GX coordinate the housing with magnets, stators or rotors?
Yes, GX can review the housing interfaces with confirmed magnetic and motor-component scope. Every supplied item and assembly operation must appear in the approved BOM.
Can GX supply waterproof motor housings?
GX can supply drawing-based waterproof housing features, but the target IP rating, seals, connectors, mating covers and complete-motor test must be defined by project.
Are aluminum, cast iron and plastic all standard GX products?
No. Aluminum and cast-iron routes are evaluated by drawing, process and project. Plastic housing capability must also be confirmed for the specific project and should not be assumed from this page.
What controls the change from sample to recurring production?
The released drawing and BOM, approved sample, tooling and fixture status, control plan, inspection methods, acceptance limits and packaging standard form the baseline.
What information affects quotation most?
Material, size, wall sections, critical tolerances, machining, finish, cooling or sealing tests, sample quantity, annual demand, documentation and packaging all affect the quotation.
