Key Advantages of the Round NEMA 34 Hybrid Stepper Motor
The 86HYD Series maintains the reliable mounting stability of a NEMA 34 square flange while incorporating a round motor body. This design offers strategic advantages in industrial systems:
- Reduced Rotor Inertia: The round motor body minimizes overall mass compared to a full square frame, enabling faster acceleration and deceleration times for dynamic positioning cycles.
- Rotary Tables & Gimbals: The circular profile is ideal for direct integration into rotary indexers, robotic joints, and surveillance gimbals for a balanced, aesthetic fit.
- Heavy-Duty Applications: Utilizes the powerful NEMA 34 frame size to provide robust holding torque for large-scale automation and material handling equipment.

Frequently Asked Questions (FAQ)
Q: What is the primary difference between the 86HYD (Round Body) and 86HSD (Square Body) Series?
A: Both are NEMA 34 hybrid stepper motors and use the standard square 86×86 mm mounting flange. The key difference is mass and inertia: the 86HYD (Round Body) typically has lower rotor inertia, making it preferable for dynamic applications requiring quicker start/stop cycles, while the 86HSD (Square Body) often excels in maximizing torque density.
Q: Why choose this stepper motor over a high-power BLDC motor for my application?
A: The choice depends on the required operational speed. Stepper motors are ideal for high-torque positioning and holding a fixed position. A high-power BLDC motor would be a better choice for continuous, high-speed operation where energy efficiency and lower noise are critical.
Q: Does this 86mm round hybrid stepper motor require a special driver?
A: Yes. Given the NEMA 34 size, a high-performance industrial chopper driver is highly recommended to properly manage the current and power requirements for the 86HYD Series.
Q: What is the step angle accuracy of the 86HYD Series?
A: The 86HYD Series provides the standard 1.8° step angle (200 steps per revolution). Utilizing micro-stepping technology is the best way to achieve finer resolution and smoother operation with this industrial-grade stepper motor.
