Product Description

SOYA NEMA 34 (86mm) 3-Phase 1.2° High-Precision Open-Loop Stepper Motor Series

Achieve outstanding positioning resolution and smooth motion performance with the industrial-grade SOYA NEMA 34 series 3-phase hybrid stepper motor. Designed within a standard 86mm square frame size, this open-loop actuator utilizes a specialized 3-phase configuration and a 1.2° step angle to significantly reduce velocity ripple and eliminate low-speed resonance common in standard 2-phase models. Manufactured entirely in our own factory, it delivers maximum continuous dynamic torque across heavy industrial workloads.

Key Features & Benefits

⚡ Advanced 3-Phase Design Provides a refined 1.2° step angle (300 steps per revolution) to drastically minimize step ripple, suppress physical vibration, and elevate low-speed indexing smoothness.

⚙️ Heavy Industrial Force Output Oversized dynamic magnetic internal arrays multiply holding torque performance up to 7 kg.cm, ensuring high step consistency under severe mechanical stress.

Industrial-Grade Resonance Suppression Constructed utilizing premium low-loss silicon alloys and high-tensile shafts to heavily regulate electrical heat output and mechanical noise across endless automation cycles.

Traceable Direct OEM Customization Our direct production floor seamlessly delivers custom output configurations, including specialized keyed or flat shafts, modified wire lead extensions, and integrated pin connector housings.

Typical Applications

Precision CNC Routers & Engravers Automated Packaging & Labeling Lines Textile Machinery & Loom Actuators Industrial Conveyor Driving Systems Multi-Axis Automated Material Feeders
