Product Description:
The SE-B4.210.050-08.000 Servo Motor is manufactured by Rexroth Indramat and is designed for precise industrial automation tasks. It supports advanced industrial applications requiring accuracy, speed and reliable torque delivery.
The SE-B4.210.050-08.000 servo motor features a static torque of 18 Nm and a maximum torque of 52.0 Nm when used with SM. It operates efficiently at a nominal speed of 5000 rpm and has a ramp up time to nominal speed of 60 milliseconds. The standstill current of the motor is rated at 28 A while the peak current at 20 °C ambient temperature reaches 174 A. The torque constant is 0.64 Nm/A and the voltage constant is 68 V per 1000 rpm. The motor includes a winding resistance of 0.27 Ohms and a winding inductance of 3.3 mH. Its electrical time constant is 12.3 ms and the mechanical time constant is 4.1 ms. The thermal time constant of the servo motor is specified at 32.0 minutes. These values support its suitability for demanding high speed operations. The motor has a moment of inertia of 4.98 kgcm² × 10⁻³ and a flange dimension of 142 mm. The shaft dimension is Ø 24 × 50 mm. These dimensions enable integration into compact machine layouts without performance loss.
The SE-B4.210.050-08.000 servo motor is from the SE series and complies with shock resistance standards up to 6 g per DIN IEC 68-2-27. It maintains low noise operation with a maximum of 58 dB (A) at a 1 meter distance. The insulation class is rated ‘F’ according to VDE 0530 standards. This ensures reliable insulation at elevated operating temperatures. The motor is designed for high load cyclic operations where sustained peak torque and fast acceleration are required.
