8LSC54.ee045ff00-4 | B&R 14.6 Nm 4500 rpm Servo Motor

Introduction to the B&R 8LSC54.ee045ff00-4

When your application demands precise motion control with high dynamic response, the 8LSC54.ee045ff00-4 from B&R provides a robust solution. This three-phase synchronous servo motor is designed for excellent positioning accuracy and compact size, making it a smart choice for modern machinery.

With a nominal torque of 14.6 Nm and a nominal speed of 4500 rpm, this motor handles demanding tasks efficiently. Its permanent-magnet design ensures reliable performance, while the externally fan-cooled construction maintains stable operation even under continuous load.

Key Features and Technical Specifications

The 8LSC54.ee045ff00-4 offers a range of performance parameters that directly impact your system's efficiency and cost of ownership:

• Nominal torque: 14.6 Nm – provides ample force for medium-duty applications.
• Nominal speed: 4500 rpm – supports high-speed production cycles.
• Maximum torque: 45.0 Nm – delivers extra power for peak loads, reducing the need for oversized motors.
• Stall torque: 21.5 Nm – ensures reliable holding and start-up performance.
• Torque constant (KT): 1.09 Nm/A – translates current into torque efficiently, lowering energy consumption.
• Voltage constant (KE): 65.97 V/1000 rpm – matches drive voltage requirements for optimal compatibility.
• Stator resistance: 0.337 Ohm – contributes to predictable electrical behavior.
• Stator inductance: 4.3 mH – supports stable current control.
• Moment of inertia: 9.8 kg·cm² – balances responsiveness with system stability.
• Mass (without brake): 12.40 kg – lightweight for easier integration and reduced structural load.

These specs translate into lower energy bills and reduced downtime, because the motor operates efficiently within its designed envelope.

Applications and Use Cases

This servo motor excels in packaging, material handling, and robotic assembly lines where precision and speed are critical. For example, in a high-speed labeling machine, the 8LSC54.ee045ff00-4 maintains accurate positioning while cycling rapidly, minimizing waste and rework.

Its compact design also fits into tight spaces, allowing machine builders to reduce overall footprint and material costs. Furthermore, the motor's high overload capacity means you can handle occasional peak demands without oversizing, saving on both initial investment and ongoing energy use.

Installation and Setup

Proper installation ensures the motor performs to its full potential. The 8LSC54.ee045ff00-4 supports multiple mounting configurations per EN 60034-7, including horizontal (IM 3001) and other orientations, giving you flexibility in machine design.

The shaft end complies with DIN 748 Form E, and the flange follows DIN 42948 Form A, simplifying mechanical coupling. For electrical connections, the motor uses a connector size/type 1, and the recommended ACOPOS servo drive is model 024X, ensuring seamless integration with B&R's drive ecosystem.

Always follow the manufacturer's manual for wiring and commissioning to avoid errors that could lead to costly downtime.

Maintenance and Reliability

Routine maintenance is straightforward, thanks to the externally fan-cooled design (IC4A0A6) that keeps the motor cool even during continuous operation. The insulation class F (per IEC 60085) and thermal protection (KTY83-110 / AM-PTC1000) help prevent overheating, extending motor life.

With a thermal time constant of 40 minutes, the motor can handle short-term overloads without immediate risk, but regular inspection of the fan and cooling path is recommended. Keeping the environment within the specified operating temperature (-15 to +40°C, up to +55°C with derating) will maximize reliability and reduce maintenance costs.

Compatibility and Integration

The 8LSC54.ee045ff00-4 is designed to work with B&R ACOPOS servo drives, specifically the 024X model, ensuring optimal performance and easy setup. The motor supports feedback options like resolver or EnDat, including safety-related variants, which can be integrated into your safety system.

For installations requiring a single-cable solution, the hybrid cable option simplifies wiring and reduces installation time, lowering labor costs. Always verify compatibility with your existing control system by consulting the official B&R documentation.

Cost-Benefit Analysis

Investing in the 8LSC54.ee045ff00-4 offers long-term savings. Its high efficiency (reflected in the torque constant) reduces energy consumption, while the robust construction minimizes downtime and maintenance expenses.

Compared to lower-performance motors, this unit's ability to handle peak torque (45.0 Nm) means you can avoid oversizing, saving on both purchase price and operational costs. Additionally, the compact and lightweight design reduces structural requirements, further cutting installation expenses.
