Product Description:

The SR.A2.0041-10.000 is a synchronous servo motor from Bosch Rexroth Indramat and belongs to the SR Synchronous Servo Motors series. In industrial automation, this motor acts as a rotary actuator, converting drive current from a controlled inverter into precise shaft movement for positioning or speed-regulated tasks on packaging lines, pick-and-place axes, or material-handling stations. Because the series is designed for direct coupling with IndraDrive controllers, it forms a matched electromechanical element inside closed-loop motion systems.

The motor is energized from a DC bus rated at 670 V, allowing it to deliver high power density while keeping current levels moderate for the connected drive. A flange size of 100 mm sets the mounting interface and supports interchangeability with other IEC-pattern actuators of similar frame. When the rotor is locked, the stator can generate 4.0 Nm of torque, which is useful when the drive is sized for starting and holding demands. Position data are taken from an internal resolver that outputs 8192 incr./rev. after interpolation, and this resolution supports smooth velocity loops and repeatable indexing. The housing is sealed to IP67 except at the output flange, helping protect the motor against dust ingress and temporary immersion.

The motor has a rotor inertia of 6 × 10⁻⁴ kg·m², which balances acceleration demands against load stability during repeated motion cycles. The assembled unit weighs 7.1 kg, so installation on vertical or gantry axes adds only modest static load, and the motor has an overall length of 233 mm. Axial fixing follows the IM B5 scheme, and the shaft ends in a plain journal with a diameter of Ø14 mm and a 30 mm extension for couplings or pulleys. Natural convection cooling avoids external fans, and resolver feedback maintains ±10 angular-minute accuracy to keep position error within controller tolerances.
