Stepper Motors in Pakistan — NEMA 17, NEMA 23 | stem.pk

Stepper motors are precision DC motors that divide a full rotation into a fixed number of equal steps — typically 1.8° per step (200 steps/revolution) — giving you exact positional control without a feedback sensor. Whether you're building a 3D printer, CNC router, robotic arm, or automated lab setup, stem.pk stocks the full range of NEMA 11, NEMA 17, NEMA 23, and 5-phase Oriental stepper motors at the best prices in Pakistan.

Why Choose a Stepper Motor?

• Precise open-loop positioning — no encoder required for most applications
• High holding torque — stays locked in position when powered
• Repeatable accuracy — ideal for CNC and 3D printing axes
• Bipolar & unipolar options for different driver compatibility
• Wide voltage range — compatible with 5 V to 48 V systems

Motor Sizes at a Glance

• NEMA 11 — compact, lightweight; ideal for small robots and camera sliders
• NEMA 17 — the most popular size; standard for 3D printers, laser cutters, and Arduino projects
• NEMA 23 — high-torque; preferred for CNC routers, plasma tables, and industrial automation
• 5-Phase (Oriental / Vexta) — ultra-smooth motion with 0.72° step angle for precision instruments

Compatible Motor Drivers

Every stepper motor requires a driver to operate. All NEMA 17 and NEMA 23 motors listed here are compatible with the most popular drivers:

• A4988 & DRV8825 — microstepping drivers for 3D printers and Arduino shields
• TB6560 — single-axis 3 A driver for CNC and DIY machines
• TB6600 — 4.5 A high-current driver for NEMA 23 and above

• Camera Sliders & Telescope Mounts — silent, vibration-free tracking
• Automated Lab Equipment — syringe pumps, peristaltic pumps, XYZ stages

How to Choose the Right Motor

Match the motor to your load and driver before purchasing:

1. Frame size — NEMA 17 (42 mm) for light loads; NEMA 23 (57 mm) for heavy cuts
2. Holding torque — expressed in kg·cm or N·m; choose 20–30% above your calculated load
3. Current rating — must match your driver's output current (e.g. 1.5 A for A4988, up to 4.5 A for TB6600)
4. Step angle — 1.8° standard; use microstepping on the driver for smoother motion
