Product Description:

The SE-B4.130.050-14.000 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the SE Synchronous Servo Motors series. It works with digital drives to convert commanded current into precise rotary motion on automated packaging lines, handling units, and indexing tables. By combining a permanent-magnet rotor with internal feedback electronics, the motor supports closed-loop positioning where repeatable speed changes and accurate stopping are required. Its compact format helps it fit into machine sections where available installation space is limited.

At standstill, the motor produces a continuous static torque of 11 Nm, helping it resist external load forces. For short acceleration peaks, the winding can tolerate up to 108 A, allowing the shaft to deliver brief torque surges during rapid starts and direction changes. Its rated speed is 5000 rpm, which suits applications that require fast cycling and high linear throughput. With a torque constant of 0.61 Nm/A, the drive can relate commanded current to output torque in a direct way. Rapid command response is supported by a mechanical time constant of 10.4 ms, while the 6.3 Ω phase resistance and 0.61 mH inductance shape current rise and help reduce commutation noise during PWM switching.

The rotor inertia of 3.08 × 10⁻³ kg·m² gives the motor moderate stored energy, so velocity changes can remain quick without becoming overly abrupt. A thermal time constant of 28 min shows how quickly heat accumulates in the motor during load changes and helps the connected inverter manage overload periods. Mounting uses an IEC pattern with a 142 mm flange, while the shaft extends 50 mm from the face with a diameter of 24 mm and the housing length is 283 mm, which helps the motor fit standard machine interfaces. During operation, the back electromotive force rises at 71 V/1000 rpm, so the selected drive must match the motor's electrical behavior during high-speed motion and deceleration.
