Stepper Motors
Adampower offers a comprehensive range of stepper motors spanning from ultra-compact NEMA8 to high-torque NEMA34 frame sizes. Whether you need conventional open-loop 2-phase hybrid stepper motors, closed-loop stepper motors with integrated encoders for enhanced positional accuracy, or fully integrated motor-drive solutions with fieldbus communication capabilities, our product line covers every motion control requirement.
Product Categories
Open-Loop Stepper Motors
Industry-standard 2-phase hybrid stepper motors in NEMA8, NEMA11, NEMA14, NEMA16, NEMA17, NEMA23, NEMA24, and NEMA34 frame sizes. These cost-effective motors provide reliable open-loop operation with 1.8° step angle and holding torque ranging from 0.014 N·m to 12 N·m.
Closed-Loop Stepper Motors (with Encoder)
Stepper motors with integrated 1000-line incremental encoders that provide real-time position feedback, preventing missed steps and enabling higher efficiency, smoother motion, and greater torque at higher speeds compared to open-loop operation.
Subcategories:
- Closed-Loop Motors — NEMA17 (17IE), NEMA23 (23IE), NEMA24 (24IE), NEMA34 (34IE)
- Integrated Motors (IG Series) — All-in-one motor-drive solutions with built-in encoder in NEMA8 through NEMA34 frame sizes
