SE-KB4.065.030-00.000

The Bosch Rexroth Indramat SE-KB4.065.030-00.000 synchronous servo motor from the SE Synchronous Servo Motors series is engineered for precision motion control in demanding industrial automation environments. This compact unit delivers a Static Torque of 7.6 Nm at standstill and achieves a Nominal Speed of 3000 rpm, enabling smooth acceleration profiles. The motor supports a Peak Current of 45 A at an ambient temperature of 20 °C and exhibits a Rotor Moment Of Inertia of 1.71 kg·m² ×10⁻³, which balances torque generation with dynamic response. With a Winding Resistance (r2ph) of 3.39 Ω at 20 °C and a Winding Inductance of 30 mH, this synchronously controlled motor minimizes electrical losses. Weighing only 11 kg (excluding the holding brake), it provides an excellent power-to-mass ratio for machine integration.

Performance characteristics are defined by a Torque Constant (kt) of 1.01 Nm/A (at 40 °C) and a Voltage Constant (ke) of 114 V/1000 rpm (at 40 °C), ensuring efficient energy conversion and precise torque control. The motor’s Mechanical Time Constant (tmech) of 5.3 ms at 20 °C affords rapid acceleration in pick-and-place and CNC applications, while its Electrical Time Constant (tel) of 8.5 ms optimizes current response for sudden load changes. At standstill, the Current At Standstill rating of 7.5 A (at 105 K) maintains position accuracy under varying loads. Thermal management is enhanced by a Thermal Time Constant (ttherm) of 26 min, allowing prolonged duty cycles without overheating. These technical features combine to deliver consistent performance with minimal overshoot and vibration.

Designed for seamless integration with the SM 10/20 inverter, the SE-KB4.065.030-00.000 achieves a Maximum Torque (dependent upon inverter) of 18.8 Nm, extending its usability in high-torque applications. A standardized Dimension Flange of 185 mm simplifies mechanical installation and ensures compatibility with existing drive trains. The motor’s robust construction and precise synchronization capabilities make it ideal for robotic manipulators, CNC machinery, and automated assembly lines. With IP-class protection provided via external housings, it maintains reliable operation in harsh industrial settings. Bosch Rexroth Indramat’s synchronous servo motor family offers modular scalability and advanced control functions, supporting both standalone axes and multi-axis systems in complex automation architectures.
