Product Description:
Bosch Rexroth’s servo motor MS2N07-D0BHN-BMUH2-NNNNN-NN is built for precise motion control systems. It measures 15.12 inches in length, while its smooth shaft adds another 2.28 inches to the total longevity. This motor is designed with a power rating of 4.60 kW at nominal load and 100K temperature.
The MS2N07-D0BHN-BMUH2-NNNNN-NN motor operates at a normal rotational speed of 2000 RPM and utilizes 8.850 A of rated current to deliver 22 Nm of rated turn effect at 100 K. It supports a maximum mechanical speed of 6000 RPM and it is rated to handle a standstill torque of 22.0 Nm, while its maximum torque is measured as 79.70 Nm at 20°C and 73.2 Nm at 100 K. The motor integrates a HIPERFACE® technology encoder system with ±120” of positional accuracy and category 3 performance level. This encoder supports multi-turn 4096 absolute revolutions and requires a regulated supply of 7 to 12 V. The MS2N07 servo motor operates within a 155 (F) thermal class and it includes a self-cooling IC410 system that ensures optimal operation without external cooling requirements. Its winding takes 54 seconds and the body takes 18.70 minutes as thermal time constant to ensure proper heat dissipation during operation. The motor features a holding brake that is powered by 24 V DC and it delivers a 36.0 Nm of holding torque, along with a maximum switching energy of 850 J. The brake’s moment of inertia is 0.000410 kg·m² and it take maximum disconnection time of 200 ms.
The MS2N07-D0BHN-BMUH2-NNNNN-NN motor possess an angular rotor inertia of 0.00251 kg·m² and it offers minimal oscillations due to its level A rating. It supports only flange mounting orientation and it comes with a standard flange exactness of 5.51 inches. The unit incorporates separate rotatable power and encoder connectors for easy and safe connectivity.
Frequently Asked Questions about MS2N07-D0BHN-BMUH2-NNNNN-NN:
Q: Why is the self-cooling IC410 system important in this motor?
A: The IC410 design removes the need for external cooling, simplifying installation. It also reduces maintenance requirements and ensures consistent heat dissipation under load.
Q: What is the significance of the brake’s switched energy capacity of 850 J?
A: This value indicates the energy the brake can safely handle during switching operations. It ensures reliable stopping performance in dynamic load conditions.
Q: How does the low rotor inertia of 0.00251 kg·m² benefit performance?
A: Its lower inertia improves acceleration and deceleration response. This makes the motor suitable for dynamic applications requiring quick directional changes.
Q: What advantage does the multi-turn 4096 absolute revolution encoder provide?
A: It allows the motor to retain absolute position information without external reference. This eliminates the need for homing cycles after power loss.
Q: How does category 3 performance level of the encoder improve system reliability?
A: It ensures compliance with safety standards for automated systems. This allows integration into safety-critical applications without additional redundancy hardware.
