Stepper motor for CNC: NEMA 23 and NEMA 34
NEMA sizes describe the motor's flange: a NEMA 23 stepper motor (57 mm square) suits small routers and light axes, while a NEMA 34 stepper motor (86 mm square) gives the high torque that bigger gantries need. A stepper motor for CNC is sold best as a stepper motor and driver kit so the driver current matches the motor. A closed loop stepper motor adds an encoder so the driver can correct missed steps. Stepper motor price in India depends on frame size, torque and driver. When comparing stepper motor manufacturer options in India, check the torque curve and driver match; we quote matched kits.
Stepper motor torque calculation
For a quick stepper motor torque calculation on a ball screw axis, required torque (N·m) ≈ (axial force in N × lead in m) ÷ (2π × screw efficiency), plus the torque to accelerate the load. Then pick a high torque stepper motor with at least 50 to 100 percent margin at your working speed, because stepper torque falls as speed rises. Check the motor's pull-out torque curve, not just holding torque.
Industrial Stepper Motor: frequently asked questions
How do I choose a stepper motor for a CNC router?
Calculate the torque each axis needs, then choose a motor whose torque at your rapid speed, not just its holding torque, covers it with margin. Small routers usually use NEMA 23; larger gantries use NEMA 34. Pair it with a driver rated for the motor's current and microstepping, and consider a closed loop stepper to avoid lost steps.
NEMA 23 vs NEMA 34: which is better?
Neither is better in general. NEMA 23 motors are smaller, lighter and faster-accelerating, ideal for small routers and light axes. NEMA 34 motors give much more torque for heavy gantries, long ball screws and rack drives, but are heavier and need higher-voltage drivers. Size by the torque your axis needs at speed.
