Product Description:

Bosch Rexroth Indramat's MS2N05-B0BNN-CSSK1-NNNNN-NN Synchronous servo motor is designed for precision motion control. The self-cooling motor's 3.72 Nm rated torque and 10.6 Nm peak torque guarantee reliable operation even in demanding, ever-changing applications.

In addition to having a maximum mechanical speed of 6,000 revolutions per minute, the MS2N05-B0BNN-CSSK1-NNNNN-NN synchronous servo motor> is equipped with a 20-bit ACUROlink SIL3 encoder. This motor has a winding resistance of 10.6 ohms when it is at a temperature of 20 degrees Celsius, it has a holding brake of size 1, and it has a keyway shaft that is sealed. Additionally, it has a holding brake. Its voltage constant of 108.4 V/1000 min⁻¹ and torque constant of 1.78 Nm/A ensure that it maintains its efficiency regardless of the operating range it is in. Having a rotor inertia of 0.00028 kg·m² guarantees that the rotor will accelerate at a high rate. Additionally, the thermal time constant of 21.2 seconds guarantees that the winding temperatures will remain steady even when the operation of the rotor is prolonged. All of the requirements for industrial automation are satisfied by the servo motor, which also benefits from improved thermal management and comes in a compact case.

In accordance with the electrical specifications, the maximum RMS current should be 8.4 A, and the standstill current should be 2.29 A. The B5/IM3001 design of the motor incorporates a leakage capacitance of 1.3 nF as well as temperature sensors of the PT1000 variety. Integrated into the system is an easy due to the M23 single-cable connection and the IP65-rated enclosure, which protects it from environmental influences. Due to its encoder system, the < is SIL3 compliant.
