Product Description:
The synchronous motor 8LSA44.DB030S200-3 is made by B & R Automation as a part of their 8LS series. It operates at 400V rated voltage and a 2.80 A current while delivering a torque of 4.62 Nm. This motor is designed to provide precise position, speed and torque control in motion control systems, it is capable to integrate with ACOPOS servo drives.
The 8LSA44.DB030S200-3 8LS motor has a stationary rotor torque of 6 Nm and power rating of 1451W. It provides a nominal rotation of 3000 rev/min and possess the performance efficiency of 90.8 %. The 8LSA44 8LS motor uses an 8 Nm holding brake that ensures a stable position when the machine stops and the class F insulation allows the maximum winding temperature up to 155°C. The motor operates at an ambient temperature up to 40°C but derating rises by 10% at intervals of 10°C above 40°C, while it supports short term operation in temperatures up to 55°C, without supporting the motor's life. The 8LSA44 8LS motor provides a lift to the operations up to 2000 m above sea level and complies with IP64 levels of dust and water spray resistance with the option to add on IP65 by way of an oil seal. The shaft has form A specifications and does not have a keyway while the mounting flange conforms to DIN 42948.
The 8LSA44.DB030S200-3 8LS motor offers speedtec circular connector of size 1 for electrical interfacing which satisfies power and encoder requirement. In this model, a traditional arrangement of cables is applied while its slim and slender mechanical design saves space during installation. The housing is painted RAL 9005 flat black and it can be stored under humidity of less than 90% RH.
Frequently Asked Questions about 8LSA44.DB030S200-3:
Q: Why does the 8LSA44.DB030S200-3 motor use form A shaft without a keyway?
A: The form A shaft offers precise torque transmission with zero backlash when paired with clamping hubs. Its keyless design also simplifies assembly and reduces mechanical stress points.
Q: What is the purpose of the SpeedTec circular connector in this motor?
A: The SpeedTec connector on the 8LSA44.DB030S200-3 ensures quick and reliable electrical interfacing for power and encoder signals, minimizing wiring complexity in automation setups.
Q: How does class F insulation benefit the 8LSA44.DB030S200-3 motor?
A: Class F insulation allows the motor windings to withstand temperatures up to 155°C, enhancing durability in thermally demanding applications or enclosed environments.
Q: Why is an 8 Nm holding brake important in this model?
A: It prevents shaft movement during power loss or machine downtime, maintaining positional stability for vertical or safety-critical loads.
Q: How does the oil seal upgrade enhance its IP rating from IP64 to IP65?
A: The optional oil seal protects against low-pressure water jets from any angle, enabling the motor’s use in harsher washdown or dusty environments.
