Product Description:

The SE-B2.010.060-14.037 belongs to the SE Synchronous Servo Motors series manufactured by Bosch Rexroth Indramat. This compact AC motor is intended for positioning and velocity control in automated machinery where rapid response and repeatable motion are required. Its construction pairs a permanent-magnet rotor with an external drive so that feedback from an integrated tachogenerator can be used to close the speed loop in real time.

The motor has a nominal speed of 6000 rpm, which allows fast cycle completion in pick-and-place or spindle duties. A torque constant of 0.41 Nm/A links drive current directly to output torque, giving predictable control tuning. Short bursts up to a maximum torque of 2.6 Nm (SM 5/10) enable the axis to clear inertia peaks without stalling, while a peak current of 14 A is the highest electrical demand the inverter must handle. The motor’s electromagnetic circuit has a winding inductance of 47.6 mH; together with the winding resistance of 13.4 Ω, this sets the electrical time constant that shapes current rise and influences servo bandwidth. During continuous standstill, the phase current is 2.5 A, keeping the stator below thermal limits under static load.

When the shaft is held motionless, the magnetic coupling delivers a static torque of 1.0 Nm, and an integral holding brake supplements this with 3.5 Nm to secure vertical loads once power is removed. The brake is energized from a regulated supply of 24 V ±10% and typically draws 0.7 A. Speed feedback is provided by a tachogenerator that produces 1.8 V per 1000 rpm with a ripple not exceeding 1.5%, allowing the drive to monitor velocity accurately. The generated back EMF follows a voltage constant of 41 V/1000 rpm, information that the controller uses for sensorless checks and for refining field-oriented algorithms.
