Product Description:

The MS2N05-B0BNN-CMSL1-NNNNN-NN is a low inertia three-phase synchronous servo motor manufactured by Bosch Indramat for accurate motion control. It is designed to cool itself by allowing heat to naturally flow and dissipate. This synchronous motor has an integrated advanced 20-bit multi-turn feedback encoder that record indirect position within 4096 mechanical rotations.

The MS2N05-B0BNN-CMSL1-NNNNN-NN servo motor develops 3.72 Nm turning effect at 2850 revolutions per minute. Its rated power is 1.11 kW while the rated current is 2.36 A. With standard ball bearings this motor can achieve a peak 6000 rotations of speed to act fast and precise. When the temperature is 100K it produces 4.45 Nm at stationary position and draws 2.75 A. The MS2N05 servo motor possess torque value of 1.78 Nm/A at 20 °C while the voltage is specified as 108.4 V/1000 revolutions. The motor is able to increase and decrease its speed rapidly since its rotor moment of inertia is 0.00028 kg·m² and it is designed with five pole pairs to boost its effectiveness. At 20 °C the winding resistance is 10.6 Ω, minimum inductance of 56.4 millihenry and a leakage capacitance of 1.3 nF. The MS2N05 servo motor takes 21.2 seconds for the winding’s temperature to settle and 12.7 minutes for the entire motor’s temperature to return to normal.

The MS2N05-B0BNN-CMSL1-NNNNN-NN servo motor offers an electrically release holding brake. The holding brake can exert up to 10 Nm at 24 Volts and in just 30 ms, the brake engages and it takes another 80 ms to release. The MS2N05 servo motor comes with half keyway balanced seal shaft that is 40mm in length and 19mm in diameter. It supports single rotatable cable connection and weighs 5.1 kg without the brake.
