Product Description:

The SE-B2.020.030-14.005 is a synchronous servo motor produced by Bosch Rexroth Indramat in the SE Synchronous Servo Motors series. Designed for industrial positioning and velocity loops, the unit couples with a compatible drive controller to move pick-and-place arms, indexing tables, or small transfer stations. By converting commanded current into controlled shaft torque, it lets automation equipment execute repeatable motion profiles with minimal lag. The motor is suited to compact servo axes where fast starts, stops, and position corrections are required.

The motor operates at a nominal shaft speed of 3000 rpm, which serves as a reference point for selecting gear ratios and feedback scaling. A torque constant of 1.10 Nm/A links drive output current directly to mechanical torque, simplifying control tuning. During acceleration or disturbance rejection, the controller may deliver up to 16 A of peak phase current, while steady standstill operation draws 2.7 A to produce 2.9 Nm of static torque. The lightweight rotor, specified at 0.44 × 10⁻³ kg·m², lowers reflected inertia so the axis responds quickly to command changes. Analog velocity feedback comes from an internal tachogenerator that produces 2.7 V per 1000 rpm with ripple limited to 1.5%, supporting smooth speed regulation.

The holding brake is supplied with 24 V DC ±10%. Once de-energized, it secures the shaft with 3.5 Nm of torque. Release and engagement each take 25 ms, and the coil draws 0.7 A, allowing frequent parking without excessive heat. Thermal behavior is modeled by a 17 min time constant, which helps estimate temperature rise during changing duty cycles. Electrical dynamics depend on the stator inductance of 76 mH and a phase resistance of 14.7 Ohm; these values affect current rise time and continuous power loss in the winding. The matched amplifier and protection devices must account for the brake load and winding behavior during operation.
