Product Description:

The SR-A0.0002.060-04.000 is a compact synchronous servo motor manufactured by Bosch Rexroth Indramat within the SR Synchronous Servo Motors series. The unit converts commanded drive currents into tightly controlled rotary motion, making it suitable for light-duty positioning axes, labeling stations, or miniature gantries where repeatable speed and angle control are required in industrial automation environments. Its small frame and sealed housing allow integration inside confined electrical cabinets or directly on moving machine parts.

An integrated holding brake supplies 1.0 Nm of static torque to secure the shaft whenever system power is removed. The brake coil is energized at 24 V DC, so it can be driven by the common control supply found in most motion systems. The housing has an IP67 protection rating, preventing dust ingress and allowing temporary submersion during washdown procedures. Mounting follows a square 55 mm flange pattern that mates with matching gearboxes and adapter plates. The rotor reaches its rated speed of 6000 rpm, enabling high cycle frequencies without exceeding the mechanical speed limit.

The electromagnetic circuit delivers a torque constant of 0.44 Nm/A, so the drive can achieve rated torque without high current peaks. Startup demand remains modest because the locked-rotor torque is 0.2 Nm and the associated stall current is only 0.45 A, easing drive amplifier sizing and cable selection. Precise feedback is provided by a resolver with a resolution of 8192 increments per revolution, supporting smooth interpolation in servo loops. A rotor inertia of 0.06 × 10⁻⁴ kg·m² promotes rapid acceleration and responsive changes in direction. The motor uses an IM B5 mounting arrangement, while its 9 mm diameter shaft has a length of 20 mm and allows direct coupling to pulleys or miniature couplings without additional bearings.
