Product Description

Overview of NEMA 11 28SHD Hybrid Stepper Motor

The 28SHD Series is a high-performance NEMA 11 hybrid stepper motor designed for precision motion control applications. Boasting a standard 1.8° step angle, it delivers exceptional positional accuracy and repeatability, making it ideal for equipment where precise movement is critical. Available in six length variants (20mm to 50mm), the series offers versatile torque options (3N·cm to 13N·cm) to accommodate diverse load demands, from lightweight consumer devices to mid-range industrial machinery.

Core Features & Durability

Crafted with premium permanent magnet materials and precision-machined components, the 28SHD Series ensures long service life and stable performance. It features flexible 4/6-pin lead designs for easy integration, IP40 protection against dust and particles, and B-class insulation (130°C) for safe operation in challenging environments. The motor’s lightweight construction (0.1-0.2kg) and low rotor inertia (7-18g·cm²) enable fast acceleration and deceleration, optimizing energy efficiency while enhancing operational responsiveness.

Electrical & Environmental Versatility

Operating at 0.3-1A rated current and 3.23-14.4V voltage, with phase resistance ranging from 3.4Ω to 48Ω, the series adapts to various driver configurations. It performs reliably in temperatures between -10°C and 50°C, with a maximum temp rise of ≤80°C, making it suitable for both indoor industrial settings and controlled outdoor applications. Whether used in continuous operation or intermittent cycles, the 28SHD Series maintains consistent torque output and positional accuracy, minimizing maintenance requirements and ensuring long-term reliability.
