Product Description:

The SR-A2.0026.060-00.000 is a synchronous servo motor built by Bosch Rexroth Indramat for the SR Synchronous Servo Motors series. Designed as a compact rotary drive element, it works with position controllers to deliver repeatable torque and velocity in automated assembly, packaging, and material-handling stations. The sealed housing protects the motor near cutting fluids or airborne dust, while stator windings built to Class F thermal limits support operation under demanding thermal conditions. These features allow the motor to be installed directly on axes that require clean, precise motion profiles without additional guarding.

At a maximum speed of 6000 rpm, the shaft can execute rapid indexing moves while remaining within the motor’s magnetic limits. The motor produces a standstill torque of 2.6 Nm with a standstill current of 3.4 A, allowing it to resist process forces when motion pauses. Command scaling is straightforward because the torque constant is 0.78 Nm/A, letting the drive convert current setpoints into predictable mechanical output. The laminated rotor has an inertia of 3.8 × 10⁻⁴ kg·m², balancing quick acceleration with low overshoot. These operating values can be used to select suitable gear ratios, evaluate cycle times, and configure current limits within the servo amplifier.

The housing meets an IP67 ingress protection rating, preventing dust and temporary water immersion from affecting the bearings or resolver cavity. The motor has a mass of 6.2 kg and an overall length of 208 mm, allowing the frame to fit compact Z-axes where clearance is limited. Its 14 mm diameter shaft has a usable length of 30 mm and transmits torque through standard keyed hubs. The mechanical structure withstands shocks of up to 6 g during emergency stops. For position feedback, a resolver provides a resolution of 8192 increments per revolution with an accuracy of ±10 arcminutes, supporting smooth interpolation at high rotational speeds.
