SE-B4.210.050-10.015

The SE-B4.210.050-10.015 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the SE Synchronous Servo Motors series. It serves as a rotary actuator that transforms regulated electrical power into controlled mechanical motion for positioning or velocity-regulated tasks in automated machinery. The unit is supplied without a holding brake, a configuration that reduces overall mass and simplifies installation in axes where an external locking mechanism already exists.

At its rated operating point the motor sustains a speed of 5000 rpm, a value that determines the electrical frequency and load profile demanded from the drive. Its static load capacity is 18 Nm, showing how much torque it can resist while stationary. A torque constant of 0.64 Nm/A means each ampere of stator current produces nearly two-thirds of a newton-meter, easing current-based torque calculations. Transient events can push supply demand to 174 A, so cabling and protective components must tolerate that peak. The rotor achieves working speed in only 60 ms, supporting short production cycles. A two-phase winding inductance of 3.3 mH shapes the current loop response time inside the controller.

The enclosure mass measures 22.0 kg, providing inertia for vibration damping yet remaining light enough for cantilever mounting. During rapid accelerations the motor delivers up to 52.0 Nm of torque, covering brief overload requirements. When the shaft is held still it draws a continuous 28 A, an important figure for thermal sizing of the drive cabinet. The generated back-EMF rises at 68 V/1000 rpm, data the inverter uses to predict regeneration voltage during deceleration. Finally, a two-phase winding resistance of 0.27 Ω limits copper losses and helps keep winding temperature within design margins during sustained high-speed operation.
