Product Description:

The SR-A2.0026.030-00.000 synchronous servo motor is manufactured by Bosch Rexroth Indramat and belongs to the SR Synchronous Servo Motors series. In an automation cell, this motor couples to a matching drive controller and delivers precise, closed-loop rotary motion for indexing tables, actuators, or light conveying axes where compact size and repeatable positioning are required. An internal resolver supplies feedback to the drive controller. Its angular precision of ±10 angular minutes supports tight velocity loops and accurate position control.

The motor mounts to the machine frame through a 100 mm flange and transmits torque through a keyed shaft measuring Ø14 × 30 mm. When the rotor is blocked, the electromagnetic system can generate 2.6 Nm while drawing a locked-rotor current of 1.7 A. These values indicate the motor’s torque and current under stationary rotor conditions. During normal operation, the windings deliver torque in proportion to current at a constant of 1.5 Nm/A, allowing the drive to apply a predictable level of mechanical output for each ampere. An A5 × 5 × 25 feather key secures couplings or pulleys to the shaft. The IM B5 mounting style aligns the housing without foot supports, leaving space for adjacent machine components.

The rotating mass, including the feedback device, has an inertia of 4 × 10⁻⁴ kg·m². This low inertia allows the shaft to accelerate quickly to its rated speed of 3000 rpm and decelerate with minimal overshoot. The motor has an overall length of 208 mm and an assembled weight of 6.2 kg, making it suitable for installation on gantries or mobile tooling. Position data are returned to the controller at a resolver resolution of 8192 increments per revolution, enabling fine interpolation between mechanical counts. The combination of low rotational inertia and resolver feedback supports responsive motion when the connected drive commands rapid changes in shaft position or velocity.
