Product Description
High-precision hybrid stepper motors are an enhanced version of standard hybrid stepper motors, designed to offer greater step resolution, improved accuracy, and smoother motion. These motors are ideal for applications that demand fine positioning, minimal vibration, and high repeatability — all without the cost or complexity of a full servo system.
NEMA17 High Precision Hybrid Stepper Motors series are standard 42mm*42mm size. 2 phase with 4 lead wires, 6wires and 3 phase with 3 lead wires. Mainly used for 3D printer, small CNC machine, precision medical equipment which need small size request. They can be mounted with 42mm diameter planetary gearbox to get more output torque.
| Feature | Description |
|---|---|
| Smaller Step Angle | Typically 0.9°/step (400 steps/rev), compared to standard 1.8° (200 steps/rev) |
| Tighter Tolerances | Higher build precision reduces internal play and backlash |
| Optimized Rotor Design | More rotor teeth and finer pole alignment improve step accuracy |
| Better Damping | Reduces overshoot and mechanical resonance |
| Microstepping Capable | Supports fine control via drivers (up to 256 microsteps per step or more) |
Motor Performance data:
