Overview

This document provides technical specifications and outline drawings for two series of non-captive shaft stepper motors: LN17 Series and LN23 Series. It includes key electrical, mechanical, and performance parameters for various models within these series.

LN17 Series Specifications

Models Covered

• LN17HT18-60
• LN17HT18-75

Key Parameters

Notes: Step angle is consistent at 1.8° for both models. The 2-phase model has higher detent torque and rotor inertia compared to the 4-phase model.

LN23 Series Specifications

Models Covered

• LN23HT18-70
• LN23HT18-130

Key Parameters

Notes: Both models have a 1.8° step angle. The LN23HT18-130 has a higher rated current and lower resistance per phase compared to LN23HT18-70. Gear reduction ratios differ significantly, affecting torque and speed characteristics.

Summary of Critical Parameters and Recommendations

• Step Angle: Uniformly 1.8° across all models, suitable for precise positioning applications.
• Electrical Characteristics: Resistance and inductance per phase vary significantly between models and phases, impacting current draw and response time.
• Torque: Detent and holding torque values indicate the motor's ability to resist external forces when stationary; higher torque models are preferable for load-intensive applications.
• Gear Reduction: Present in LN23 series, gear ratios affect output torque and speed; selection should match application requirements.
• Mass and Inertia: Important for dynamic performance; lower inertia allows faster acceleration.

Users should select models based on the balance of torque, speed, electrical consumption, and mechanical constraints relevant to their application.
