Product Description:

The MS2N07-C1BNN-CMUH1-NNNNN-NN servo motor is manufactured by Bosch, and the motor is designed with a compact structure for effective integration with mechanical systems. The design enables advanced encoder technology and precise motion control. The motor type contains a holding brake, which improves operating stability during the application cycle.

The MS2N07-C1BNN-CMUH1-NNNNN-NN servo motor features a 140 mm flange and a 130 mm spigot. The shaft length is 58 mm, with a diameter of 32 mm. The shaft of the motor is smooth, and the motor does not include a shaft seal. The shaft's mounting hole is M10, which allows for secure mechanical attachment. The motor can deliver a maximum torque of 46.0 Nm. The standstill torque is 11.5 Nm at 60k with internal cooling and 14.5 Nm at 100k with either internal or exterior cooling. The brake type is "1". Without the brake, the angular inertia is 0 kg/m², but with the brake, the rotational inertia is 0.00331 kg/m². The maximum speed is 6000 RPM. The encoder resolution is 20-bit digital, with ACURO@link's SIL2 PL d safety level. The encoder is multiturn, with a total of 4,096 absolute revolutions. The cooling method is self-cooling. The weight is 14 kilograms. The electrical connection is made using a rotatable angle connector M23. The motor has IP64 protection. The rotor's inertia type is medium.

The 165 mm bolt circle and mechanical dimensions of the MS2N07-C1BNN-CMUH1-NNNNN-NN servo motor are compatible with standard mounting configurations. The encoder and braking systems are designed to operate within the limitations of their torque and speed ratings. The cooling system guarantees consistent thermal efficiency. The electrical connector may be easily installed in systems due to its location and rotational capabilities.

Frequently Asked Questions about MS2N07-C1BNN-CMUH1-NNNNN-NN:

Q: Why does MS2N07-C1BNN-CMUH1-NNNNN-NN use a smooth shaft design?

A: The smooth shaft allows easy coupling with compatible mechanical interfaces. It reduces assembly complexity and supports applications where keyed or splined shafts are unnecessary.

Q: How does MS2N07-C1BNN-CMUH1-NNNNN-NN achieve 0 rotor inertia without a brake?

A: The rotor is manufactured with optimized materials and geometry. This configuration allows reduced inertial mass that enables faster acceleration and deceleration profiles.

Q: Why does MS2N07-C1BNN-CMUH1-NNNNN-NN use a multiturn encoder design?

A: The multiturn encoder tracks multiple revolutions without power loss. This ensures precise position tracking in extended motion sequences without requiring homing after power cycles.

Q: How does MS2N07-C1BNN-CMUH1-NNNNN-NN maintain IP64 protection level?

A: The motor housing uses sealed construction with precision-fitted components. This prevents the ingress of dust and limits water spray, protecting internal electrical and mechanical parts.

Q: Why does MS2N07-C1BNN-CMUH1-NNNNN-NN use Size 1 brake type?

A: The Size 1 brake matches torque and shaft dimensions. It ensures effective holding force without oversizing for the motor’s operational load capacity.
