Product Description

SOYA NEMA 34 (86mm) Industrial Open-Loop Stepper Motor Series

Empower your heavy-duty mechanical engineering projects with the rugged SOYA NEMA 34 series 1.8° hybrid stepper motor. Engineered specifically within a standard 86mm square frame size to manage severe mechanical workloads and high-inertia loads, this open-loop actuator utilizes oversized core shafts and optimized magnetic structures to output massive mechanical holding torque. Manufactured entirely on our own shop floor, it delivers exceptional dynamic stability across multi-shift automated setups.

Key Features & Benefits

⚡ Severe Heavy-Duty Torque Oversized internal rotors generate extreme continuous holding torque, preventing positional drift or slipping under high pulling, milling, or cutting stress.

⚙️ 4-Lead & 8-Lead Wiring Adaptability Available in industrial 4-lead and 8-lead configurations, providing motion engineers with ultimate wiring freedom for optimized series, parallel, or unipolar control.

Exceptional Thermal Endurance Constructed with ultra-low-loss magnetic alloys and reinforced bearings to dramatically minimize electrical heat generation during continuous factory operation.

Traceable OEM Customization Our direct manufacturing plant seamlessly builds customized shaft geometry (keyed, round, flats), modified wire extensions, and integrated terminal pin blocks.

Typical Applications

Heavy CNC Milling Machines Industrial Plasma Cutting Tables Large Packaging Automation Gantries Industrial Valve Regulators & Actuators Heavy Textile Looms Multi-Axis Robotic Manipulators
