Product Description:

The SE-B5.440.020-10.011 is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the SE Synchronous Servo Motors series. It is intended for precision positioning and speed control in automated assembly stations, packaging equipment, and handling axes, where the drive system translates commanded current into repeatable mechanical motion. This operating role suits applications that require stable torque delivery, predictable acceleration, and accurate response to changing load conditions.

A mounting flange diameter of 190 mm centers the housing and provides a stable reference plane for coupling to gearboxes or machine frames. During transient acceleration, the motor can deliver up to 123 Nm of torque when paired with an SM 50/100 drive, while continuous operation is based on a nominal speed of 2000 rpm. The windings accept peak drive output of 207 A, so the associated inverter must supply that current while maintaining controlled current regulation. A front gasket and sealed cable ports provide an enclosure rating of IP65, permitting installation in areas exposed to dust or low-pressure washdown and helping protect internal components from contamination.

The keyed shaft measures Ø32 × 58 mm, providing a mechanical interface that withstands the static torque of 52 Nm without slippage. System responsiveness is aided by a rotor inertia of 18.6 ×10⁻³ kg·m², which helps the motor balance quick speed changes with smooth running under varying loads. Electrical conversion is characterized by a torque constant of 1.51 Nm/A, and back EMF rises at 167 V/1000 rpm, which the drive DC bus must accommodate. The coils have 5.0 mH of inductance and 0.26 Ω of resistance, influencing current ripple and heat generation during high-frequency PWM control. The standstill current limit is 35 A, and flange accuracy R together with vibration severity grade R support aligned operation and stable mechanical balance in continuous industrial service.
