Product and supply scope
What Is an AC Motor Housing?
An AC motor housing or frame supports the stator and end covers, establishes shaft height and mounting geometry, transfers reaction loads and removes heat through the frame and cooling fins. Standard-looking frames can still differ in pilots, feet, flange, terminal-box orientation and machining datums.
GX supplies drawing-defined AC motor housings and confirmed mechanical interfaces. Ceiling-fan, blower, HVAC, pump and other application-specific housings are evaluated from the actual drawing and project requirements rather than presented as standard stock products.
Project route
Translate the IEC or NEMA Interface into Controlled Cast and Machined Datums
The route connects frame standard, material, casting or fabrication, bore and foot machining, surface protection and dimensional release.
Interface Review
Confirm frame standard, mounting form, shaft height, stator, covers and terminal box.
Material Route
Evaluate aluminum casting/extrusion, iron casting or fabricated steel from duty and volume.
Frame Forming
Produce the approved blank with ribs, feet, flange and required machining stock.
Stabilize and Clean
Remove sand or flash, blast and stabilize the blank before final machining.
Machine Interfaces
Bore stator and cover pilots; machine feet, flange, box opening, drains and threads.
Coat and Inspect
Protect the frame, mask fits and verify dimensions, coating and trial interfaces.
Verification
Verify Shaft Height, Mounting and the Complete Bore-to-Cover Chain
Inspection combines standard mounting dimensions with the project-specific stator, end-cover, terminal-box and coating requirements.
| Control item | Method / evidence | Buyer benefit |
|---|---|---|
| Standard mounting | Height gauge, CMM and dedicated frame fixtures | Confirms shaft height, feet and flange geometry |
| Stator / cover pilots | Bore gauges, roundness and coaxiality measurement | Controls air gap and bearing-axis alignment |
| Feet and flange | Flatness, parallelism and hole-position checks | Prevents rocking and installation stress |
| Cooling features | Visual, dimensional and coating-thickness inspection | Maintains fin geometry and corrosion protection |
| Special boundaries | Drain, terminal-box and sealing checks by drawing | Supports the complete-motor enclosure design |
Application fit
Where AC 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.
Industrial Drives
Frames for conveyors, machinery and general-purpose induction motors.
Pumps and Compressors
Foot or flange housings reviewed for sealing environment, corrosion and bearing alignment.
Fans and HVAC
Project-evaluated housings reviewed for airflow, compact mounting and terminal orientation.
Inverter-Duty Motors
Frames reviewed for thermal load, encoder provisions, vibration and cooling configuration.
Project control
Documented Control for Drawing-Based AC 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.

FAQ
AC Motor Housing Sourcing Questions
Clarify the drawing, interfaces, process route, operating conditions, test boundary and supplied BOM before comparing quotations.
Can GX supply standard IEC motor frames?
GX reviews the requested IEC frame, mounting form and detailed drawing. The page does not mean every IEC size is stocked or that every material and configuration is a standard GX product.
What is the difference between B3, B5 and B35 housings?
B3 is foot mounted, B5 is flange mounted and B35 combines feet and a flange. The drawing must still define pilot, PCD, holes, shaft height and terminal-box orientation.
Should we choose aluminum or cast iron?
Aluminum reduces mass and transfers heat efficiently; cast iron offers stiffness, impact resistance and vibration damping. Geometry, load, environment, quantity and machining determine the final choice.
Can the terminal-box position be changed?
It can be evaluated through casting layout, removable feet, machining or a project-specific box interface. State the required top/side position and cable direction.
How is shaft height controlled?
Shaft height depends on foot datums, end-cover and bearing geometry, stator bore and machining setup. It must be inspected with the released mounting datum rather than inferred from the outer casting.
Can GX claim the complete motor is IP55 or IE3?
No. IP and efficiency ratings belong to the complete assembled and tested motor. GX supplies the housing geometry, material and finish specified for the customer's motor design.
Are fan, blower and HVAC housings standard products?
They are project-evaluated products. Provide the drawing, airflow and mounting package, materials, tolerances, environment and annual demand for feasibility review.
What should be included in an AC housing RFQ?
Provide IEC/NEMA reference, B3/B5/B14/B35 form, 2D/3D files, stator and end-cover interfaces, material, coating, environment, sample quantity and annual demand.
