Product Description:
The SE-B5.440.020-00.000 synchronous servo motor is manufactured by Bosch Rexroth Indramat and belongs to the SE Synchronous Servo Motors series. Serving as an electromechanical actuator in industrial automation, it turns commanded phase current into regulated torque and speed for packaging lines, pick-and-place axes, and general motion platforms. Resolver feedback and permanent-magnet excitation give the connected drive controller the closed-loop data needed to position loads repeatedly over long production runs without drift. This arrangement also lets the drive correct speed error quickly when the load changes during indexing or transfer moves.
Operating at a nominal shaft speed of 2000 rpm, the unit provides a continuous static torque of 52 Nm, and acceleration reserves reach 123 Nm for brief intervals. The drive amplifier must be able to source a peak phase current of 207 A, while the standstill requirement is 35 A for load holding. Each ampere produces predictable output because the torque constant is 1.51 Nm/A, and the voltage constant is 167 V/1000 rpm for speed-related back EMF. Dynamic electrical response includes an 18.6 ms electrical time constant and a phase inductance of 5.0 mH, which influence current rise and switching ripple. Copper loss is based on a 0.26 Ω winding resistance, and torque is transferred through a keyed Ø32 × 58 mm shaft on a 190 mm flange interface.
The rotor’s mechanical response time is only 2.0 ms, so speed changes follow control commands almost immediately. A reflected inertia of 18.6 × 10⁻³ kg·m² balances quick indexing with stable motion, which helps the axis remain responsive without becoming overly sensitive to load disturbances. The total motor mass of 39 kg adds rigidity at the machine interface and helps the housing resist repeated start-stop forces. Thermal modeling assigns a 52-minute time constant, permitting intermittent overload without rapid temperature rise when adequate airflow is available. This behavior is useful on cycles that alternate between short bursts of high demand and longer dwell periods.
