Why Is the Big AC Servo Motor a Critical Component for High-Power Industrial Automation?

In industrial automation, high-power applications such as CNC machining, laser cutting, and heavy-duty packaging require motors that deliver consistent torque, precise control, and reliable performance under demanding conditions. The Big AC Servo Motor from LICHUAN is designed specifically for these applications. With power ratings ranging from 2.7KW to 11KW, 180mm flange construction, and support for multiple encoder types, these motors provide the strength and precision needed for heavy industrial equipment. This article examines the technical specifications, key features, and applications that make this motor series a practical choice for automation professionals.

The Need for High-Power Servo Motors in Modern Industry

As industrial automation continues to advance, the demand for high-power servo motors has grown significantly. Applications such as CNC machining centers, large-format laser cutters, and heavy-duty packaging lines require motors capable of delivering substantial torque while maintaining precise position and speed control. Unlike smaller servo motors used in light-duty applications, big AC servo motors must handle higher inertial loads, operate continuously under demanding conditions, and provide reliable performance over extended periods.

The Big AC Servo Motor from LICHUAN is engineered to meet these requirements. With a 180mm flange design and power ratings from 2.7KW to 11KW, this motor series is suitable for a wide range of heavy industrial applications. Supported by CE and RoHS certifications, and backed by a comprehensive quality assurance system, LICHUAN has established itself as a reliable supplier of motion control solutions. This article provides an overview of the motor's specifications, features, and applications.

Product Specifications

The Big AC Servo Motor series from LICHUAN includes multiple models with varying power ratings and voltage options. Below is a summary of the key specifications for the 180mm flange series.

Additional models are available with power ratings up to 11KW. The motors support 2500ppr, 17-bit incremental, and 17-bit absolute encoders, with brake options available for applications requiring holding torque.

Key Features and Performance Characteristics

The Big AC Servo Motor series from LICHUAN incorporates several design features that contribute to its performance and reliability in demanding industrial environments.

High Torque Density

The 180mm flange design provides a robust mounting platform that supports high torque output. The motors deliver holding torque ranging from 17.2 N·m to 48 N·m, with peak torque capabilities up to 96 N·m. This torque density makes the motors suitable for applications that require high force or heavy load handling.

Smooth and Quiet Operation

The motors are designed for smooth operation with very low noise levels. This is achieved through precision manufacturing and balanced rotor construction. The low noise characteristic is particularly important in environments where noise pollution is a concern, such as medical equipment manufacturing or precision laboratory applications.

Multiple Encoder Options

The motors support a range of encoder types, including 2500ppr incremental encoders, 17-bit incremental encoders, and 17-bit absolute encoders. This flexibility allows system integrators to select the appropriate feedback resolution for their specific application requirements. The absolute encoder option is particularly useful for applications that require position retention after power loss.

High Protection Rating

With an IP66 protection rating, the motors are dust-tight and protected against powerful water jets. This makes them suitable for use in harsh industrial environments where dust, moisture, or washdown procedures are common.

Wide Operating Temperature Range

The motors are designed to operate reliably in temperatures ranging from -20°C to +50°C, with humidity levels below 90% RH (non-condensing). This wide operating range ensures consistent performance in various factory environments.
