Product Description:

The product MS2N07-C0BNN-RSUB0-NCNNN-NN Synchronous Servo Motor is manufactured by Bosch Rexroth which specializes in a wide array of industrial and mobile automation solutions like servo drives and actuators. The motor has standstill torque that is rated at 12.8 Nm at 60K with a corresponding current of 6.9 A.

The MS2N07-C0BNN-RSUB0-NCNNN-NN Synchronous Servo Motor has a static torque that increases to 16 Nm while drawing 8.8 A current at a thermal state of 100K. This interrelation allows stable performance under elevated thermal conditions. The motor offers a nominal torque of 12.65 Nm at 100K with a current specification of 7.05 A. It supports a rated speed of 2640 rpm which allows reliable operations in motion control systems. For short-term peak performance the maximum torque reaches 38.8 Nm at 20 °C with a peak current of 24.8 A. This enables the motor to manage high-load tasks with short bursts of energy without compromising performance. It has a rotor inertia of 0.0012 kgm² which supports fast dynamic response. The peak speed is 6000 rpm for making it suitable for high-speed precision applications. The torque constant is 2.01 Nm/A with the voltage constant of 122.0 V/1000 min⁻¹ for predictable and linear control output.

The MS2N07-C0BNN-RSUB0-NCNNN-NN Synchronous Servo Motor is built with 5 pole pairs and comes with a thermal time constant of 46.4 seconds. This allows accurate thermal modeling for safe continuous use. The leakage capacitance is 2.42 nF which minimizes signal interference. The unit has a total mass of 12 kg for robust yet suitable for compact installations. The winding resistance is rated at 1.58 ohms and the inductance is 23.2 mH for low power loss and stable electromagnetic behavior.
