Product Description:

The SG-A2.027.049-00.000 Synchronous Servo Motor created by Bosch Rexroth is highly in-demand due to its exceptional performance and maintenance-free operations. It is aligned with the series of SG Synchronous Servo Motors.

The SG-A2.027.049-00.000 synchronous servo motor diameter of its centering flange (pilot) is 64 mm which is used to precisely align the motor with a mounting surface and ensures accurate and repeatable mounting to a compatible machine interface. It is constructed to operate with a nominal operating speed of 5500 rpm. The SG motor is fully protected under IP 65 rating. The time it takes for the motor’s current to reach approximately 63% of its final value after a voltage step is applied is 0.155 ms which implies fast current response. The signal connector which is used for feedback, such as encoder signals is located at the top-right side with a 19 mm offset. The power connector is situated at top-left and with a 19 mm offset. The acceptable level of vibration the motor is expected to produce or withstand is grade N which is the normal grade or R which is reduced vibration.

The SG-A2.027.049-00.000 synchronous servo motor weight is 3.6 kg which matters for load calculations, robotic arm payload planning and installation. It has a design of IM B5 which is flange mounted design. The diameter of the circle on which the mounting bolts are arranged is 115 m which ensures mechanical compatibility with gearboxes, couplings or machine interfaces. A torque constant of 0.41 Newton meters per amp means that for every ampere supplied, the motor generates 0.41 Nm of torque. The SG-A2.027.049-00.000 servo motor comes with a one year warranty by Wake Industrial.

Frequently Asked Questions about SG-A2.027.049-00.000:

Q: How does the 0.155 ms time constant improve the servo motor's performance?

A: A low electric time constant allows the motor to respond quickly to control input changes. This enhances real-time precision in dynamic motion applications.

Q: Why is the IP65 protection rating important for the SG-A2.027.049-00.000 motor?

A: IP65 rating protects the motor from dust and low-pressure water jets. It enables reliable use in challenging environments like machining or packaging.

Q: What role does the 64 mm pilot diameter play in installation accuracy?

A: The pilot diameter centers the motor accurately to avoid shaft misalignment. This ensures precise load coupling and reduces mechanical stress.

Q: Why is the SG-A2.027.049-00.000 servo motor ideal for high-speed operations?

A: Its nominal speed of 5500 rpm supports applications requiring fast and consistent movement. This makes it suitable for robotics and high-speed conveyors.

Q: How does the top-left power plug location benefit installation design?

A: Positioning the power plug on the top-left side simplifies cable routing. This is especially useful in compact or enclosed machine frames.
