Product Description:

The SE-B4.130.050-00.000 is a synchronous servo motor produced by Bosch Rexroth Indramat within the SE Synchronous Servo Motors series. It is intended for high-performance industrial axes where precise velocity regulation and rapid torque development are necessary for coordinated motion, indexing tables, or packaging machinery. Used with a compatible servo drive, the motor converts commanded current into controlled rotary motion for applications that require quick starts, fast reversals, and stable operation during repeated cycle changes.

This model reaches a nominal rotor speed of 5000 rpm, allowing fast traverse rates, while the static torque capability of 11 Nm holds loads steadily at zero speed. A torque constant of 0.61 Nm/A links drive current to output torque. When the controller supplies the rated current at M0 of 18 A, the shaft produces the declared stall torque. The back EMF voltage constant is 71 V/1000 rpm, which supports drive control during speed changes. Mechanical mounting follows an IEC flange with a 130 mm pilot, and power is transmitted through a 24 mm diameter shaft that is 50 mm long and fitted with an A8×7×40 key. The overall housing length is 283 mm. The stator phase resistance is 0.61 Ω and the phase inductance is 6.3 mH, which influence the electrical load seen by the inverter and the way current rises in the windings.

Dynamic behavior is shaped by a maximum intermittent torque of 34.0 Nm, which can be applied for short accelerations without thermal overload. A rotor inertia of 3.08 × 10^-3 kg·m² balances quick acceleration with stable running, while the electrical time constant of 10.4 ms shows how quickly current builds in the windings during command changes. The motor mass is 16.0 kg, providing structural stiffness for rigid mounting. The keyed shaft integrates with couplings or gearboxes to transmit motion without slip, and the combination of inertia and shaft geometry supports steady power transfer during rapid axis movement.
