Product Description:

The SR-B4.0172.060-00.015 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the SR Synchronous Servo Motors series. As a rotary actuator, it converts supplied electrical energy into precise mechanical motion, driving packaging machinery, pick-and-place modules, and other position-controlled axes in industrial automation. Its compact frame and standardized flange simplify mechanical integration, while the resolver feedback system keeps the drive under closed-loop control.

During dynamic duty cycles, the motor reaches a rated speed of 6000 rpm, giving machine builders a wide velocity range before field weakening is needed. A torque constant of 0.65 Nm/A links drive current to output torque, simplifying current-loop tuning. During startup, the motor can deliver a locked-rotor torque of 17 Nm, while the windings can withstand a locked-rotor current of up to 26 A to support rapid indexing under load. The combined rotor and encoder inertia is 0.004 kg·m², allowing fast acceleration with modest drive power. Position feedback is supplied by a resolver that returns 8,192 increments per revolution, and two integrated NTC temperature sensors allow the drive to reduce current if the winding temperature approaches its limit.

Electrical integration is provided through a 670 V DC link, so the motor can pair with high-voltage IndraDrive inverters without intermediate transformers. Operating noise does not exceed 58 dB(A), helping machinery meet workplace sound targets. The housing can withstand impacts of up to 6 g, and the bearings are rated for 20,000 hours of service before overhaul. A single size 1.5, 8-pin output connector carries resolver signals, while power conductors with cross-sectional areas of up to 16 mm² can be crimped to the stator terminals. The resolver has a precision of ±10 angular minutes, limiting position error during fine indexing routines.
