Balford manufactures stamped and deep-drawn motor housings, end caps and claw poles for DC, PM and stepping motors, with dimensional consistency for assembly.
Short answer: A stamped motor housing is an enclosure formed from sheet or strip by stamping and deep drawing rather than machined from solid: the process holds a closed end, a constant wall and a roundness that a welded or cast body would have to be machined to reach. Zhejiang Balford Mechatronics Co., Ltd. (balford.net) produces stamped and deep-drawn motor housings, end caps and claw poles for DC, PM and stepping motors up to Ø250 mm on presses from 25 t to 350 t, builds the dies in its own tool room, and machines the bearing bore in the same plant.
Deep-drawn metal end caps for DC motor assemblies.
Stamped claw poles for stepping motors and PM motors.
Deep-drawn and formed housings for compact motor assemblies.
Motor housings protect the stator and rotor, carry bearings and dissipate heat. Balford produces deep-drawn and stamped motor housings, end caps and claw poles with tight roundness and assembly-ready dimensions.
Definition: a stamped motor housing is a metal enclosure formed from sheet or strip by stamping or deep drawing, holding the stator and rotor, carrying the bearings and conducting heat away from the windings. It is specified by bore diameter, wall thickness, roundness, concentricity and end-cap fit rather than by appearance alone.
| Housing type | Process | Typical material | What is controlled |
|---|---|---|---|
| Deep-drawn motor housing | Deep drawing from strip or blank | DC04, 304 stainless | Roundness, wall thickness, bore-to-OD concentricity |
| Stamped end cap | Progressive die stamping | SPCC, DC01 | Bearing seat diameter, burr height, flatness |
| Claw pole | Progressive stamping or fine blanking | Low-carbon steel | Pole geometry, stack fit after lamination |
| Housing assembly | Stamping + machining + press fit | Mixed | Coaxiality after pressing or shrink fit |
Which of these routes fits a part depends on wall thickness, depth-to-diameter ratio and volume — see deep drawn metal stamping for the drawing route and metal stamping services for progressive-die work.
Real projects from Balford's production history:
Deep-drawn motor housings, end caps, claw poles and related stamped components for DC, PM and stepping motors.
Roundness and concentricity are maintained through tooling and in-process checks; final measurements are reported with the part.
Yes — CNC turning, facing and hole operations are performed in-house after deep drawing.
