2. What is the holding torque of the Bachin Stepper Motor 424015A? The holding torque of the Bachin Stepper Motor 424015A is 4.2 Ncm (5.9 oz-in).
3. What is the rated current of the Bachin Stepper Motor 424015A? The rated current of the Bachin Stepper Motor 424015A is 1.5 A.

• Four-wire bipolar configuration: two coils (A/A– and B/B–).
• Drive method: Current-controlled chopper drivers recommended (e.g., A4988, DRV8825, TMC-series) for consistent torque across speeds and to avoid overheating.
• Microstepping: Supported by driver; use 1/2, 1/4, 1/8, 1/16 microsteps to reduce resonance and improve positional smoothness.
• Suggested wiring: Identify coil pairs with an ohmmeter; typical coil resistance few ohms. Connect coils to driver outputs (A+/A–, B+/B–).
