Product Description:

The QSY090B-030-HG1-UN is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the QSY Synchronous Servo Motors series. This brushless unit delivers controllable torque and speed in automated machinery, allowing compatible drives to position loads quickly and repeatedly. In industrial automation, it commonly powers indexing tables, pick-and-place arms, and conveyor axes that require precise cycling and electronic gearing.

During continuous operation at a winding temperature of 100 K, the motor reaches a rated shaft speed of 3000 rpm. At that speed, it delivers a continuous torque of 8.5 Nm, providing twisting force for constant loads. The corresponding mechanical output is 2.7 kW, providing sustained power for production equipment. To achieve this output, the windings draw a phase current of 6.6 A while the drive supplies a line-to-line voltage of 330 V. These electrical ratings allow the motor to maintain thermal equilibrium during continuous operation. The power and voltage levels are suitable for compatible medium-power inverter modules and standardized DC-bus arrangements.

For short bursts lasting up to 200 ms, the inverter may command a current of 42.0 A, increasing electromagnetic excitation for rapid acceleration. During that interval, the shaft can deliver a peak torque of 43.5 Nm, giving the axis enough reserve force to overcome static friction or transient shock loads. When the rotor is locked, the motor can produce a stall torque of 13.0 Nm while remaining within the applicable current and thermal limits. The motor has 4 pole pairs, which establish the synchronous relationship between the stator field and rotor magnets. This arrangement permits smooth sinusoidal commutation throughout the operating speed range. A 9-pin flange socket provides the electrical connection between the motor and drive while supporting a secure cable interface.
