Product Description:
The SG-A2.027.049-13.010 Servo Motor of Bosch is designed for efficient motion control operations. It is part of the SG Synchronous Servo Motors series. This unit offers dependable performance in industrial automation and control applications.
The SG-A2.027.049-13.010 servo motor has a standardized mechanical dimension for mounting that complies with international standards such as IEC 72-2 and DIN 42948 which ensures compatibility with other mechanical components like gearboxes or brackets. It is included with a small holding brake which locks its shaft when power is off and it doesn’t stop a moving motor but holds its position when stationary. It is designed for high speed applications as its normal operating speed is 5500 revolutions per minute. It transmits torque securely to the driven element such as pulley and gear with help of keyway and featherkey which prevents slipping under load. To track the rotor's position it is featured with a resolver which is a feedback device. It is rugged and reliable and converts position into analog signals. For every 1 amp of current the motor is able to produce 0.41 nm torque which helps in estimating the drive requirements and also speaks to the motor's efficiency in torque production.
The static torque value of the SG-A2.027.049-13.010 servo motor is 2.6 nm which it can produce when stationary under rated conditions. It comes with an insulation class of F which shows the thermal durability of its winding insulation that can handle up to 155°C. It has a compact size with length equals to 147 mm which suggests it is designed for space-constrained applications. During stationary position it draws 6.8 A current which is called stall current on which the motor generates maximum holding torque.
Frequently Asked Questions about SG-A2.027.049-13.010:
Q: How does the resolver improve rotor position tracking accuracy in this servo motor?
A: The resolver in the SG-A2.027.049-13.010 provides analog signals for precise rotor tracking. This enhances closed-loop control and maintains synchronization during high-speed operations.
Q: Why is a brushless resolver preferred over an optical encoder in this model?
A: A brushless resolver offers better durability in harsh environments and is less prone to failure. It's ideal for applications requiring stable performance under vibration or temperature fluctuations.
Q: What role does the torque factor of 0.41 Nm/A play in system efficiency?
A: A higher torque factor means more torque per unit current, improving overall power efficiency. It reduces energy losses and helps select compatible drive electronics.
Q: Why is the static torque important for the SG-A2.027.049-13.010 servo motor?
A: Static torque ensures the motor can hold position against load when stationary. This is crucial for maintaining precision in paused or holding states.
Q: How does the holding brake enhance safety in vertical axis applications?
A: The holding brake prevents shaft movement when power is off, avoiding unwanted load drops. It increases reliability in lift or press-type machinery.
