RFQ Checklist for NEMA Stepper Motor OEM Projects

Most RFQ delays come from missing technical inputs, not factory response speed. If you provide the data below in round one, your supplier can usually return a usable quotation and engineering feedback much faster.

1. Product Definition

• NEMA frame size: NEMA 8 / 11 / 14 / 17 / 23 / 24 / 34 / 42
• Motor type: hybrid, geared, hollow shaft, integrated driver, etc.
• Required holding torque and target speed range
• Operating voltage/current and driver preference

2. Mechanical Interface

• Shaft type, diameter, length, and tolerance
• Mounting pattern and available installation space
• Connector type and cable length
• Any gearbox, coupling, or encoder requirement

3. Application Conditions

• Application scenario: CNC, medical device, packaging, textile, robotics, etc.
• Duty cycle and motion profile (continuous, indexing, frequent start/stop)
• Ambient temperature, humidity, vibration, and contamination risks
• Target service life and maintenance expectations

4. Commercial and Supply Scope

• Prototype quantity and mass production forecast
• Target Incoterm (EXW/FOB/CIF/DDP) and destination country
• Required documentation (COC, test report, compliance file, labeling)
• Desired first delivery window and replenishment rhythm

5. Quality and Validation

• Critical CTQ items (torque consistency, noise, runout, temperature rise)
• Incoming inspection standard and AQL preference
• Whether PPAP/FMEA/control-plan style documents are required
• Traceability requirement (lot code, production date, serial tracking)
