Product Description:

Bosch Rexroth Indramat manufactured the MRS102F-2N-0035-NNNN motor. The key spec of this motor is maximum torque 68 Nm, which determines its ability to generate high rotational force. Torque is a critical parameter in industrial motors as it defines the motor’s ability to drive loads. The high torque of this motor is for applications that need high mechanical force, such as spindle drives in CNC machines or high speed cutting tools. And the maximum speed 22,500 min⁻¹ is for high speed machining process. The motor runs with rated power 10.1 kW and rated speed 3,000 min⁻¹ to balance power and speed. The rated power determines the efficiency of energy conversion so the motor can deliver maximum mechanical output while minimizing loss.

The rated torque 32 Nm is for sustained performance under load, which is essential for consistent force application in automation. To support this, the motor need input voltage range 380-440 VAC at 50/60 Hz to be compatible with standard industrial power systems and give flexibility for different regions and electrical standards. Thermal management is crucial for high-performance motors, and this motor is air-cooled to maintain optimal operating temperature. Air cooling is for effective heat dissipation to prevent excessive thermal buildup that can affect efficiency or damage internal components.

The motor has rotor moment of inertia 0.005 kgm², which affects its acceleration and deceleration. A lower moment of inertia means faster dynamic response, which is good for applications that need frequent and precise adjustment. The step interference fit of the rotor mounting is for secure mechanical integration to minimize misalignment and mechanical loss. For system integration, the motor needs manual parameterization during startup to align its characteristics with the drive controller. This is for the optimization of performance by fine-tuning critical parameters such as speed control, torque limit and feedback mechanism. And with maximum current 100 A and rated current 15.3 A, the motor can handle high power demand while still efficient.
