Product Description:

The SE-B2.030.060-10.000 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the SE Synchronous Servo Motors series. It is intended for industrial automation tasks that require repeatable rotary positioning, such as pick-and-place stations, light gantries, or compact spindle drives. By converting electrical energy into controlled mechanical rotation, the motor serves as the primary actuator in a closed-loop axis where speed and torque are regulated by an external drive controller.

The motor reaches a nominal speed of 6000 rpm, which is the continuous shaft velocity sustained under rated electrical conditions. A static torque of 3.0 Nm is available at standstill for holding duty when no motion is commanded. With a torque constant of 0.42 Nm/A, each ampere supplied to the phase windings produces that amount of electromagnetic torque, allowing fast force estimation inside the servo loop. Transient acceleration demands can draw a peak current of 45 A, while the standstill current remains at 7.5 A during continuous holding duty. The windings have an inductance of 14.0 mH, which affects current rise time, and a resistance of 2.25 Ω that contributes to copper losses. When thermal conditions permit, the shaft can deliver 7.8 Nm of maximum torque for short overload intervals.

A rotor inertia of 0.60 × 10⁻³ kg·m² balances dynamic response with load stability, supporting rapid cycle operation without excessive controller gain. The back-EMF gradient is 45 V/1000 rpm, a value used by the drive to estimate speed during coast or regeneration states. With a mass of 7.6 kg, the unit can be mounted on moving carriages without adding significant payload. The motor uses a square flange of 100 mm and a 14 mm diameter by 30 mm shaft that mates to standard couplings. Overall length is limited to 254 mm, which helps the motor fit into machines where installation depth is restricted.
