Product Description:
The 8LMA54.DB022CG00-0 Synchronous Servo Motor is designed for precise motion control applications. It delivers efficient power, stable performance and durability under demanding conditions. It features a flange mount, IP rated enclosure and electromagnetic brake for secure positioning.
This B & R Automation 8LMA54.DB022CG00-0 servo motor provides a rated torque of 7.1 Nm and a maximum static torque of 8 Nm. The motor supports a rated speed of 2200 rpm. It operates on a rated voltage of 400 V and draws a rated current of 3.2 A with a peak current of 3.61 A. The motor is built with a 3 phase winding configuration and features Class F insulation that allows for continuous operation at temperatures up to + 155 °C. It is designed with a winding temperature reference based on a + 40 °C ambient environment. The shaft of this servo motor is a keyed type and comes with a coupling adapter for secure mechanical integration. Its flange mount is square shaped and includes four bolt holes for firm installation. The enclosure of this motor is rated IP64. This makes it dust tight and resistant to water splashes from any direction. These features support the motor’s reliability in industrial settings with moderate exposure to contaminants.
The 8LMA54.DB022CG00-0 servo motor includes an integrated electromagnetic brake for holding torque that ensures static positioning when powered off. The brake operates at 18 V DC and delivers a holding torque of 15 Nm which prevents shaft movement under load. The servo motor provides dedicated connectors for power, feedback and brake control. The power is supplied via a 3 phase screw terminal. A separate brake connector is provided for easy integration into control systems.
Frequently Asked Questions about 8LMA54.DB022CG00-0:
Q: How does the 8LMA54.DB022CG00-0 servo motor maintain shaft position under load during power-off states?
A: The integrated electromagnetic brake delivers 15 Nm holding torque to prevent shaft drift during shutdowns. Operating at 18 V DC, it ensures static positioning in load-bearing conditions.
Q: Can the B & R Automation 8LMA54.DB022CG00-0 servo motor sustain high thermal loads in continuous duty applications?
A: It uses Class F insulation to handle winding temperatures up to +155 °C. The design assumes a +40 °C ambient reference, ensuring stability in high-duty thermal cycles.
Q: How does the 8LMA54.DB022CG00-0 motor perform in industrial environments with airborne particulates and light moisture?
A: Its IP64-rated enclosure offers complete dust protection and resists water splashes from any angle. This makes it ideal for moderate industrial contamination levels.
Q: How does the keyed shaft and adapter system in 8LMA54.DB022CG00-0 affect coupling in automation setups?
A: The keyed shaft offers precise torque transmission, reducing slippage. It includes a coupling adapter for secure mechanical integration into preexisting drive assemblies.
Q: What current control strategies should be considered when integrating the 8LMA54.DB022CG00-0 servo motor into a closed-loop system?
A: It runs at a rated current of 3.2 A with a peak current of 3.61 A during transients. A well-matched drive should account for these parameters to prevent overshoot or thermal stress.
