Product Description:

The QSY112B-030-HG0-BN synchronous servo motor is built by Bosch Rexroth Indramat for the QSY Synchronous Servo Motors series. The unit converts electrical input from a drive into controlled mechanical rotation for positioning tasks in industrial automation equipment, such as packaging axes and pick-and-place modules. It follows the series conventions for flange geometry, feedback interface, and thermal class, supporting precise velocity and torque regulation in multi-axis machines.

During continuous operation, the motor delivers a mechanical output of 1.9 kW at a rated shaft speed of 3000 rpm. At this operating point, it supplies 6.0 Nm of torque while the windings are energized with a rated voltage of 278 V. The electromagnetic design uses four pole pairs, allowing the associated drive controller to generate high-resolution commutation signals. Under these conditions, the thermal model uses a 100 K winding temperature rise and permits a rated current of 5.4 A. These steady-state values support the selection of power electronics and cable cross-sections while helping account for heat dissipation inside the machine enclosure.

For axis startup or brief overloads, the magnetic stack supports a stall torque of 32.0 Nm while the windings carry 28.8 A at the same 100 K reference. When acceleration peaks last no longer than 200 ms, the drive may command up to 102.0 Nm while drawing momentary current pulses of 113.5 A. These transient limits permit rapid indexing without exceeding the permissible winding temperature. The difference between the rated and peak values provides headroom for motion profiles that include fast reversals or sudden load changes while maintaining position accuracy. Drive settings must keep the duration of acceleration peaks within the stated time limit to prevent excessive thermal loading during repeated operating cycles.
