SPIDER Automation 86HS115-6004 NEMA 34 Stepper Motor | 87 kg-cm Heavy-Duty Industrial Stepper Actuator
Description
If you are building a large CNC mill, CNC lathe, or a heavy-duty CNC router, the SPIDER Automation 86HS115-6004 NEMA 34 Stepper Motor is your perfect choice. The most attractive feature of this monster stepper motor is the massive 87 kg-cm of holding torque it provides. Operating as an open-loop brushless DC motor, it is a true powerhouse built specifically to withstand the heavy mechanical demands and high-torque requirements of large-scale industrial machinery. Featuring a standard 1.8 degree step angle, a robust 5A per phase operating current, and a customized 14mm keyway-type shaft designed for maximum stability during high-power operations, this motor ensures exceptional reliability, precise positioning, and an excellent dynamic response to starting, stopping, and reversing pulses.
Key Features
- Massive Industrial Torque: Delivers up to 87 kg-cm of holding torque at 5A current per phase.
- Keyway-Type Shaft Design: Features a secure 14mm shaft with a keyway slot to lock pulleys and drive gears firmly in place, eliminating slip under heavy loads.
- High-Speed & High-Performance: Built to operate smoothly at exceptionally high speeds compared to smaller NEMA 17 or standard NEMA 23 motors.
- Precise Step Accuracy: Maintains a standard 1.8 degree step angle with a high step accuracy of around 3 to 5 percent per step.
- Open-Loop Simplicity: Driven easily via standard stepper drivers without requiring complex feedback circuitry.
Benefits
- Superior Power Handling: Significantly more powerful and robust than smaller frame sizes, making it ideal for heavy cutting and milling forces.
- Slip-Free Transmission: Keyway shaft prevents high-torque shear slippage during aggressive acceleration and deceleration.
- Smooth Dynamic Response: Excellent starting, stopping, and reversing characteristics under heavy industrial workloads.
- Long Operational Life: Quality-approved industrial collection designed for high reliability and extended service life in demanding environments.
Applications
- Large CNC Mills & Routers: Heavy gantry drives and high-torque axis motion.
- Industrial CNC Lathes: Precision spindle and carriage feed systems.
- Heavy Plasma & Laser Cutters: Large-format cutting tables requiring robust stepper actuation.
- Industrial Automation Jigs: High-load positioning systems and heavy material handling rigs.
