Product Description

The AC servo motor SF-A5.0460.030-10.030 is manufactured by Bosch Rexroth. This module has a frame size of A5. The rated speed (nN) at which this module can operate continuously is 3000 RPM. This module has a locked-rotor torque (M0) of 46 Nm. The stall torque is the maximum torque a motor can produce at zero speed or when it first starts. The locked-rotor current at M0 (I0) is equal to 29 A. This is also known as the stall current. This means the module draws 29 A of current when it is not rotating and delivers the maximum torque. The value of the torque constant (KT) for this device is 1.58 Nm/A. Every ampere of current will generate 1.58 Nm of torque.

This servo motor has a moment of inertia (J) equal to 166×10-4 kgm2. This value describes its resistance to changes in its rotational motion. A higher moment of inertia means it requires more torque to accelerate or decelerate. The flange size (SW) of this device is 190 mm. The flange is a flat surface with holes for bolts. It is used to attach the motor to a machine or other device.

The mass of this module without the holding brake (m) is 35 kg. This is the weight of the motor itself, excluding any optional holding brake. The encoder can measure the motor's position with an accuracy of 20 arcseconds. One arcsecond is 1/3600th of a degree. And the encoder divides one complete rotation of the motor shaft into 8 million distinct positions. The precision tells us how accurately the encoder can measure the motor's position. On the other hand, resolution refers to the smallest detectable change in position. Don't miss out on the added protection of a one-year warranty on this servo motor.
