Product Description:
The SE-B4.130.050-14.010 is a synchronous servo motor produced by Bosch Rexroth Indramat for the SE Synchronous Servo Motors series. It converts electrical energy into controlled rotary motion for positioning tasks in automated assembly cells, pick-and-place gantries, and packaging stations. Flange accuracy grade R supports precise alignment between the motor, coupling, and driven equipment, helping the connected axis maintain consistent positioning during repeated movements.
The nominal speed of 5000 rpm provides a rated operating point for continuous shaft rotation under load. The motor can deliver up to 34.0 Nm of torque for short-duration peaks, while its static torque of 11 Nm indicates the continuous torque available at zero speed. To produce its static torque, the drive must supply a standstill current of 18 A, and acceleration phases can draw a peak current of 108 A at 20 °C. Dynamic response is supported by an electrical time constant of 10.4 ms, allowing current to rise quickly after a command. The integrated holding brake provides 18 Nm of holding torque and operates from a 24 V ±10% supply while drawing 1.0 A. The stator circuit has an inductance of 6.3 mH and a resistance of 0.61 Ω, which the drive uses to regulate winding current and control torque output.
Torque production is characterized by a constant of 0.61 Nm/A, meaning each ampere of motor current produces slightly more than half a newton-meter of torque. During rotation, the back electromotive force rises at 71 V/1000 rpm, which helps determine the voltage needed from the connected inverter across the operating range. A rotor inertia of 3.08 × 10^-3 kg·m² supports rapid acceleration while maintaining rotational stability during speed changes. Thermal loading is moderated by a winding thermal time constant of 28 min, allowing the motor to tolerate intermittent overloads before winding temperature approaches its operating limit. The electrical and thermal characteristics support controlled current delivery during fast indexing, repeated acceleration, and precise low-speed motion. When the axis stops, the integrated brake can secure the shaft and prevent the connected load from drifting after motor torque is removed.
