Product Description

Overview of NEMA 17 42SHM Hybrid Stepper Motor

The 42SHM Series is a high-precision NEMA 17 hybrid stepper motor (42mm size aligns with NEMA 17 standard) engineered for ultra-fine motion control. Its 0.9° step angle delivers double the accuracy of 1.8° motors, with 6 length variants (21-48mm) and 10-44N·cm torque to fit light-to-mid-heavy load demands.

Key Features & Reliability

Constructed with premium permanent magnets and precision-machined rotors, it supports 4/6-pin integration for flexible driver matching. IP40 dust protection and B-class insulation enhance durability in industrial environments, while its 0.13-0.38kg design balances power and responsiveness. It adapts to 0.4-2.4A current and 2.4-12V voltage, maintaining stable performance across -10°C~50°C operating temps.
