Product Description:

The Bosch Rexroth Indramat’s MS2N07-C0BNN-BMUK1-NNNNN-NN Servo motor offers a consistent holding torque of 20 Nm, which holds its position when it is in idle, assuring system stability. The rated power of this servo motor is 3.5 kW at 100K to deliver a steady energy supply for motion control applications.

This synchronous motor consumes a rated current of 7.05 A during thermal reference conditions of 100K to ensure energy-efficient operation in industrial applications. This servo motor supplies a peak torque of 35.7 Nm at 100K, well-matched for demanding acceleration and deceleration cycles. With a maximum current rating of 24.8 A, the MS2N07-C0BNN-BMUK1-NNNNN-NN servo motor is capable of supporting high-load spikes without sacrificing system reliability. Designed with a multi-turn absolute encoder, this synchronous motor is capable of up to 4,096 revolutions to enable precise and continual position monitoring. This motor’s winding inductance is 23.2 mH, which serves to contribute to its electromagnetic behavior and affects the current rise time. The thermal time constant of the winding of this motor is 46.4 seconds, which represents the time taken by the winding to come to thermal equilibrium. The MS2N07-C0BNN-BMUK1-NNNNN-NN motor is of thermal class 155 (F) as per EN 60034-1 to demonstrate high-temperature resilience and long-life operation.

This MS2N07-C0BNN-BMUK1-NNNNN-NN Servo motor's cooling mode is self-cooling, free from the use of external fans or forced cooling, thus easing installation and minimizing system complexity. The shaft type of this motor possesses a keyway with half-key balancing and a shaft sealing ring for vibration reduction, dust, and oil protection. This motor possesses a leakage capacitance of 2.42 nF, which plays its part in system-wide EMC (electromagnetic compatibility) considerations. The holding brake’s connection time of this motor is restricted to 40 ms to allow rapid reaction during power failure or emergency braking.
