Product Description:

The QSY112B-030-HG1-AN belongs to the QSY Synchronous Servo Motors series produced by Bosch Rexroth Indramat. It is a brushless AC synchronous unit intended for closed-loop positioning and velocity control in industrial automation lines, where repeatable motion is required for gantry axes, packaging stations, and material transfer modules. By integrating with Rexroth digital drives, the motor provides rapid dynamic response while maintaining compact frame dimensions suitable for cabinet or machine-mounted installations.

Its continuous operating point has a rated speed of 3000 rpm, where the shaft can deliver up to 1.9 kW of mechanical output. At this duty point, the stator operates at a phase voltage of 278 V and requires a phase current of 5.4 A. The resulting electromagnetic field produces a rated torque of 6.0 Nm, which is suitable for moderate-load conveyors or indexing tables. Internally, the motor uses 4 pole pairs to support smooth commutation and accurate low-speed performance. These continuous ratings assume a 100 K winding temperature rise and serve as the basis for selecting a matching inverter and power cable gauge.

When motion demands exceed the continuous point, the motor can supply a stall torque of 32.0 Nm while the windings can carry 28.8 A without exceeding the same thermal limit, enabling static holding of vertical axes or rapid acceleration from rest. For very short bursts of up to 200 ms, the permissible winding current climbs to 113.5 A, producing a peak torque of 102.0 Nm. These transient capabilities let servo amplifiers execute fast point-to-point moves without mechanical oversizing. The combination of high momentary torque and moderate thermal inertia widens the usable duty cycle window, maintaining positional accuracy during load changes and minimizing cycle times in pick-and-place or press-feeding applications.
