Product Description:

Bosch Rexroth Indramat SE-B5.440.020-14.000 Servomotor is a high-performance motor designed for accurate motion control requirements. For industrial automation, the servomotor works reliably and efficiently, meeting all the needs of the field.

The SE-B5.440.020-14.000 servomotor has a torque constant of 1.51 Nm/A, which makes sure that the output torque is stable. At 1000 rpm, the voltage stays the same at 176 V. At a temperature of 20°C, the high current is 207 A, and the current is 35 A when nothing is happening. At 20°C, the wiring has a resistance of 0.26 Ohm and an inductance of 5 mH. The electric time constant is 18.6 ms, which makes sure that the current responds quickly. The mechanical time constant is 2 ms, which lets the speed go up quickly. The servomotor has a thermal time constant of 52 minutes, which makes it more stable at low temperatures. With a voltage ripple of ≤ 1.5%, the built-in tacho generator gives an EMF of 2.7 V per 1000 rpm. The holding brake has a holding torque of 56 Nm that keeps the position stable. The brake's input voltage is 24V ±10%, which allows it to work consistently.

The 190 mm flange size of the SE-B5.440.020-14.000 servomotor makes it compatible with normal mounting arrangements. The shaft is 58 mm long and 32 mm wide, which makes it strong enough to hold mechanical loads. The torque at rest is 52 Nm, and the torque at its strongest is 123 Nm. The time it takes to get to full speed is 36 ms. When it comes to conditions that require both dynamic reactivity and stability, the servomotor is designed to function efficiently and correctly.
