Product Description:
The QSY112B-030-HP1-BN is a synchronous servo motor produced by Bosch Rexroth Indramat in the QSY Synchronous Servo Motors series. Designed for industrial automation, it connects to digital drives to provide precise position and velocity control for pick-and-place arms, packaging stations, and light machining spindles. Electrical commutation is sinusoidal, while a four-pole rotor supports smooth torque production across controlled motion profiles. The motor’s feedback system allows the connected drive to monitor shaft movement and correct deviations caused by changing loads.
During steady-state operation, the motor can deliver a rated mechanical output of 1.9 kW. This power is available at a shaft speed of 3000 rpm, producing a continuous torque of 6.0 Nm while drawing 5.4 A from the drive at a phase voltage of 278 V. During a stall, the torque capability rises to 32.0 Nm and the current demand increases to 28.8 A; these values support drive tuning for holding and low-speed indexing tasks. Feedback is supplied by an ERN 1387 incremental encoder, and sinusoidal commutation helps minimize torque ripple during rotation. The DIN 42948 / IEC 72 flange and ISO-R775 shaft provide standardized mechanical attachment to compatible equipment. An 11-pin flange socket provides connections for power and brake wiring without requiring a separate terminal arrangement.
For short bursts, the winding withstands a peak current of 113.5 A, permitting acceleration torque of up to 102.0 Nm for 200 ms without thermal overload. This temporary capacity supports rapid acceleration when machinery reverses direction, indexes a load, or begins a demanding movement. The brief duration limits heat accumulation in the winding while allowing the drive to provide the current needed for dynamic motion. Electrical insulation supports a maximum DC bus voltage of 565 V, providing additional voltage capacity for regenerative energy produced during rapid deceleration. Proper drive configuration must keep the applied current, voltage, and transient duration within the motor’s operating limits.
