NHM Series External Five-Star

Motor Overview

TheNHM Series External Five-Star Motoris a specialized industrial motor designed for high-precision, high-efficiency, and robust performance in demanding applications. Below is a structured breakdown of its key features, technical specifications, applications, and advantages:

------

1. Key Features

• Five-Star Rotor Design

• Uniquefive-pole rotor structure(compared to traditional 3- or 4-pole designs) enhances torque stability, reduces vibration, and improves dynamic response.

• Suitable for applications requiringlow-speed, high-torqueoperation with minimal pulsation.

• External Mounting Configuration

• Direct-drive external mountingeliminates the need for gearboxes or couplings, reducing mechanical losses and maintenance.

• Simplifies installation in compact spaces or retrofits into existing systems.

• High-Precision Control

• Optimized forservo, stepper, or variable-frequency drive (VFD) systems, enabling precise speed and position control.

• Lowcogging torqueand smooth operation ensure high accuracy in CNC machinery, robotics, and automation.

• Industrial-Grade Durability

• IP65/IP67 protection(dust-tight and waterproof) for harsh environments.

• High-temperature resistance(up to 120°C or higher, depending on insulation class).

• Corrosion-resistant materials(e.g., stainless steel shaft, epoxy-coated housing) for outdoor or chemical-exposed use.
