NEMA Frame Stepper Motors

Standardized NEMA 8/11/14/17/23/24/34/42 product lines for industrial motion platforms with OEM-ready customization options.

Target Buyer:Best for sourcing teams that need stable multi-size supply under one vendor with repeatable drawings and lot consistency.

Capability Highlights

Select frame size by required torque at real operating RPM, not holding torque only
Match winding current with driver continuous current and enclosure thermal condition
Freeze shaft/flange tolerances early to avoid coupling and assembly rework

Metric	Typical Range	Why It Matters
Frame size coverage	NEMA 8 to NEMA 42	Supports one-vendor strategy across multiple machine modules.
Holding torque band	0.03 to 12+ N·m (model dependent)	Sets static reserve before dynamic validation at speed.
Winding strategy	Low-voltage/high-current to high-voltage winding	Determines driver pairing and thermal envelope.
Typical prototype lead time	7 to 21 days (custom scope dependent)	Affects NPI gate planning and pilot schedule.

Model chosen by frame convention only: Validate torque margin at target RPM with at least 30% continuous reserve.
Mechanical mismatch at assembly: Lock one drawing revision in RFQ and PO, including runout/concentricity notes.
Thermal drift during field duty: Run 30-60 minute duty-cycle validation before sample sign-off.

Yes. We support NEMA 8 to NEMA 42 under one process flow, with size-by-size technical confirmation during RFQ.

No. Final selection should use torque at target speed, acceleration profile, and thermal constraints.
