Product Description:
The SG-A3.055.049-03.000 Servo Motor is designed to achieve high reliability and un-interrupted power supply in industrial facilities. This model refers to the SG Synchronous Servo Motors series. The manufacturer of this SG motor is Bosch Rexroth.
The SG-A3.055.049-03.000 servo motor dissipates heat through thermal radiation in which heat is emitted from the surface of the motor as infrared radiation. It also can dissipate heat via natural convection in which air flow due to temperature difference carries heat away. The standards for the motor winding interface are IEC 72-2 and DIN 42948 which specifies dimensions for the mounting flange and ensures compatibility with standard mechanical setups, so it can easily be mounted to gearboxes or machinery without custom parts. Its current consumption at standstill position is 13 amperes which indicates the amount of electrical load it creates when holding a position. 4800 revolutions per minute is the nominal speed of the motor which is relatively fast that suggests it is designed for high-speed applications. The shaft of this module is precisely centered and rotates with minimal wobble as it complies with DIN 42955-R which is a standard for high precision rotating components.
The diameter of the SG-A3.055.049-03.000 servo motor flange is 140 mm which is large and suggests a physically bigger motor, usually with higher torque and power handling. The servo motor provides a powerful holding torque capability of 5.8 nm torque. A keyway on the motor shaft functions as a slot that stops loose connections between shaft and coupling along with the feather key mechanism that allows secure coupling of the motor shaft to gears and pulleys while under torque.

Frequently Asked Questions about SG-A3.055.049-03.000:
Q: How does the keyway and featherkey design help in torque transmission?
A: The keyway and featherkey prevent shaft slippage, ensuring torque is reliably transmitted. This design secures the connection to gears or couplings under load.
Q: Why is DIN 42955-R compliance important in servo motors like SG-A3.055.049-03.000?
A: DIN 42955-R ensures minimal shaft runout and precise coaxially. This is critical for applications requiring high rotational accuracy and minimal vibration.
Q: What advantage does natural convection cooling provide for SG-A3.055.049-03.000 in tight installations?
A: Natural convection requires no additional fans or components. It enhances reliability and is ideal for confined spaces with limited airflow.
Q: How does a 140 mm flange benefit the SG-A3.055.049-03.000 servo motor's performance?
A: A larger flange offers greater stability and load-handling capacity. It also simplifies integration into robust mechanical structures.
Q: Why is a standstill current of 13 A necessary for SG-A3.055.049-03.000?
A: This ensures strong holding torque when the motor is not rotating. It supports load retention in precision positioning tasks.
