SE-B4.090.050-10.000

The SE-B4.090.050-10.000 servo motor is produced by Bosch Rexroth Indramat and belongs to the SE Synchronous Servo Motors series. Designed for high-speed positioning tasks in automated machinery, this permanently excited synchronous unit converts drive current into continuous rotary motion while supplying feedback to the drive controller. Factory lines use the motor to accelerate tooling or conveyor axes quickly and hold commanded speed under varying load conditions.

At a nominal shaft speed of 5000 rpm, the motor reaches its rated operating point, and the drive can accelerate from zero to this velocity in 60 ms, allowing tight cycle times on pick-and-place heads. During rapid transients the inverter may supply up to 85 Amps of phase current, whereas at standstill the continuous requirement falls to 14 A. A static torque of 8.0 Nm is available for holding or low-speed creep, generated proportionally to the torque constant of 0.57 Nm/A. Inductance between the two active phases is measured at 9.0 mH, and the 0.94 Ω phase resistance limits steady-state copper losses.

For short overload events the electromagnetic design permits a ceiling torque of 23.0 Nm without demagnetization. The rotor’s reflected mass is only 2.18 × 10⁻³ kg·m², so speed reversals can be executed with minimal servo gain adjustment. Thermal behavior is characterized by a 27 min time constant, giving the winding ample time before reaching its rated temperature after load changes. Back-EMF rises at 68 V/1000 rpm, providing predictable feedback for voltage-controlled drives and defining the regenerative threshold. This constant also assists the controller in tuning current loops and prevents over-voltage trips during deceleration. Routine inspections of products are held to identify and fix any physical damage and faults before shipment. Wake Industrial stocks this servo motor with a one year warranty.
