Product Description:

The QSY112B-030-HP0-BN is a synchronous servo motor produced by Bosch Rexroth Indramat within the QSY Synchronous Servo Motors series. The motor is designed for high-precision drive axes in packaging machines, transfer lines, and assembly cells. Permanent-magnet excitation and electronic commutation provide rapid torque buildup and repeatable positioning, allowing controllers to execute demanding motion profiles without mechanical play. By connecting directly to an IndraDrive amplifier, the unit converts regulated DC bus power into controlled shaft rotation for continuous or interpolated motion tasks.

Under nominal conditions, the motor delivers a power output of 1.9 kW at a shaft speed of 3000 rpm. At that operating point, it produces a continuous torque of 6.0 Nm while drawing 5.4 A from a drive that supplies a phase voltage of 278 V. The motor uses 4 pole pairs, so the electrical frequency is four times the shaft’s rotational frequency. Power is supplied through an 11-pin flange socket that accepts a composite cable with four 6 mm² conductors and two 1 mm² auxiliary conductors. The cable requires a minimum bend radius of 85 mm to prevent insulation fatigue during installation and operation.

For intermittent peak loads, the shaft can generate up to 102.0 Nm while the current rises to 113.5 A; the associated inverter must accommodate these overload values during rapid acceleration. When the rotor is locked, the magnetic circuit permits a stall torque of 32.0 Nm with a corresponding stall current of 28.8 A, enabling the axis to resist static loads for permitted stall periods. The difference between the rated and stall operating regions supports thermal modeling, while the cable and connector arrangement helps maintain acceptable conductor temperatures during periods of increased torque production.
