17HA 42mm 0.9° Hybrid Stepper Motors

What Is a Hybrid Stepper Motor?

A  custom hybrid stepper motor combines the design principles of permanent magnet (PM) and variable reluctance (VR) stepper motors to achieve superior performance. Key features of the 17HA 42mm 0.9° Hybrid Stepper Motor include:

· High Resolution: A 0.9° step angle (finer than standard 1.8° motors) enables precise angular control.

· High Torque: Dual-phase windings and a multi-toothed rotor deliver strong holding torque (e.g., 350 mN·m for the 17HA401Y-13B model).

· Wide Compatibility: Available in bipolar (4-wire) and unipolar (6-wire) configurations for flexible driver integration.

· Industrial Durability: Rated for -20°C to +80°C operation and 500V insulation, suitable for harsh environments.

What Is the Difference Between a Hybrid Stepper Motor and a Servo Motor?

What Are the Three Types of Stepper Motors?

1.Permanent Magnet (PM) Stepper Motors

· Mechanism: Magnetized rotor aligns with electromagnetic stator poles.

· 17HA Context: Less common in this series; hybrid designs dominate for precision.

2.Variable Reluctance (VR) Stepper Motors

· Mechanism: Tooth-structured rotor aligns with stator poles to minimize reluctance.

· 17HA Context: Typically lower torque than hybrid types.

3.Custom Hybrid Stepper Motors

· Mechanism: Combines PM and VR designs—multi-toothed rotor with axial magnet.

· 17HA Advantage: 0.9° step angle and 350 mN·m holding torque for high-precision applications.

Why Choose the 17HA 42mm 0.9° Custom Hybrid Stepper Motor?

1. Unmatched Precision & Performance

    0.9° Step Angle: Double the resolution of standard 1.8° motors, critical for CNC machinery and 3D printers.

    Low Axial Clearance (0.08mm max): Minimizes vibration and positional error.

    High Torque-to-Size Ratio: Models like the 17HA401Y-13B deliver 350 mN·m in a compact 42mm frame.

2. Customization for Your Application

     Front/Rear Shaft Length: Up to 60mm (front) and 40mm (rear).

     Diameter Range: ф5mm–ф10mm to fit custom couplings or gearboxes.

    Wiring & Connectors: Tailor lead lengths, connectors (e.g., Molex, JST), and phase configurations (4/6-wire).

    Special Coatings: Optional IP65 ratings or food-grade lubricants for pumps.

3. Cost-Effective Reliability

· Affordable Precision: Achieves servo-like accuracy without the cost of encoders or closed-loop controllers.

· Proven Durability: 500V insulation and 100MΩ insulation resistance ensure longevity in industrial settings.

· Energy Efficiency: Low 0.4–1.0A current draw reduces operating costs.

Applications
