Product Description:
The MS2N10-E0BHA-BMTH0-NNNNN-NN Servo Motor from Bosch Rexroth Indramat features 20.5 A rated current to allow continuous power delivery with low electrical loss. The nominal power of this servo motor is 11.15 kW to handle high operational loads with high reliability.
The MS2N10-E0BHA-BMTH0-NNNNN-NN synchronous motor generates a standstill torque of 67.7 Nm at 60K and has excellent static holding ability. This servo motor provides a maximum current of 102.5 A, which enables high acceleration and temporary overload in dynamic motion. This motor features five pole pairs, which maximizes electromagnetic force distribution for even torque generation to enhance responsiveness and minimize torque ripple. The rated speed of 2000 1/min (100K) ensures that this motor maintains uniform motion across variable drive cycles while sustaining consistent rotational accuracy. This servo motor's electric efficiency is backed by 0.244 Ohm winding resistance at 20 °C, which reduces resistive heating due to prolonged use. This motor’s thermal time constant of 122.5 seconds ensures it has stable thermal characteristics during long duty cycles. Its forced ventilation axial cooling, rated at 230 V / 50 Hz, actively dissipates heat for optimal performance in demanding applications and avoids thermal overload. The housing of this servo motor with standard RAL 9005 black varnish provides corrosion resistance and surface durability.
The standard bearing type of this synchronous motor provides smooth mechanical movement and long-term operational life. This servo motor has oscillating quantity level A (EN 60034-14), ensuring its low vibration and acoustic stability even under full-rated speed. For reliable motion control, this synchronous motor incorporates a multi-turn absolute 4,096 revolutions encoder to provide precise feedback for advanced automation systems. The MS2N10-E0BHA-BMTH0-NNNNN-NN motor provides consistent output performance during installation altitudes of 0 to 1,000 meters above sea level without derating.
