Product Description:
The Bosch Rexroth Indramat QSY093B-030-HG0-AN is an AC synchronous servo motor supplied in the QSY Synchronous Servo Motors series. This frame size 093 unit connects to digital drive controllers to deliver closed-loop position and velocity control on indexing tables, pick-and-place axes, and other cyclic machinery where precise feedback is required. Using permanent-magnet excitation and four electrical pole pairs for commutation, the motor produces repeatable torque while maintaining compact overall dimensions, making it suitable for multi-axis automation cells and packaging equipment.
The motor’s electrical design is optimized for continuous operation at a rated power of 2.3 kW. During operation, it is supplied by a DC bus that yields a phase voltage of 356 V, and the stator current stabilizes at 4.7 A when the winding temperature rise is held to 100 K. A mechanical output speed of 3000 rpm is reached under nominal load, matching the speed range of many standard gear ratios. At that speed, the shaft sustains a steady torque of 7.2 Nm, producing the listed power without thermal derating. The magnetic circuit uses 4 pole pairs, allowing the encoder resolution and commutation frequency to align with typical 12 kHz inverter switching patterns and reduce torque ripple during midrange operation.
Transient operating demands are supported by a peak torque reserve of 66.0 Nm, which can be delivered for 200 ms to accelerate inertial loads or counteract brief overloads. Reaching that output requires a surge current of 51.0 A, which the connected drive must supply without exceeding its I²t limits. If the shaft is blocked, the windings can withstand a stall torque of 20.0 Nm while drawing a stall current of 13.0 A. These stall values must be considered when configuring controlled braking and holding during machine stops. The available peak output also helps the motor respond to short acceleration commands without requiring continuous operation above its nominal load.
