Product Description:

The SE-B5.440.020-10.000 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the SE Synchronous Servo Motors series. It is intended for industrial automation where precise rotary positioning and smooth speed regulation are required. The motor uses standard resolver feedback so the control system can command rapid starts, stops, and direction changes with accurate response. By converting electrical energy into consistent torque, the device acts as an electromechanical actuator for pick-and-place gantries, indexing tables, and milling axes.

From standstill, the rotor reaches its rated speed in 36 ms and accelerates to a nominal speed of 2000 rpm for typical medium-inertia loads. At that operating point, the motor can sustain continuous operation, and its maximum static output is a stall torque of 52 Nm when the drive supplies a stall current of 35 A. Torque production follows a motor constant of 1.51 Nm/A, which helps the drive relate current to output torque. The electrical time constant is 18.6 ms, and the winding resistance is 0.26 Ω, so both values affect the initial current rise. A smooth shaft with a diameter of 32 mm and a length of 58 mm transfers power to couplings, and a mating connector is not included.

The mechanical response is governed by a rotor inertia of 18.6 ×10⁻³ kg·m², which supports dynamic accuracy while helping stabilize heavier assemblies. Total motor mass is 39 kg, and the housing length does not exceed 395 mm, which helps the unit fit inside compact machine frames. Heat generated during cyclic duty is absorbed by the stator and released over a thermal time constant of 52 min, allowing extended operation under elevated load without additional cooling. During motion, the back EMF rises in proportion to speed, and its magnitude is expressed by a voltage constant of 165 V/1000 rpm, which helps the drive account for induced voltage during PWM control and regeneration.
