Specifications
Type: NEMA 28 Stepper Motor
Step Angle: 1.8° (200 steps per revolution)
Holding Torque: ~0.67 Nm (67 kg-cm)
Rated Current: 0.67 A/phase
Voltage: Typically, 2-3 V (depends on the driver used; low voltage motors rely on high current drivers)
Phase Resistance: ~4-5 Ω
Wiring: Bipolar (4 wires: A+, A-, B+, B-)
Wiring
A typical bipolar stepper motor has four wires. Identify the wire pairs:
Use a multimeter to measure resistance.
Two wires with continuity belong to one coil (e.g., A+ and A-).
The remaining two wires belong to the second coil (e.g., B+ and B-).
Recommended Driver
DRV8825 (up to 2.2 A with cooling)
A4988 (up to 1 A without cooling, 2 A with cooling)
TB6600 (for higher current and torque applications)
