Product Description:

The MS2N07-D0BHN-ASUK2-NNNNN-NN is a servo motor that features a compact construction that incorporates a flange size of 140 mm and a spigot of 130 mm. With a total weight of 21.1 kg, the motor is designed with a holding brake and a keyed shaft design that integrates a shaft seal.

The MS2N07-D0BHN-ASUK2-NNNNN-NN servo motor can go as fast as 4000 rpm and have a maximum torque of 79.7 Nm. When cooled from the inside at 60k, the standstill power is 22.0 Nm. When cooled from the inside or outside at 100k, it rises to 28.2 Nm. There is a low-inertia rotor in the motor. Its value is 0.00251 kg/m² with the brake and 0 kg/m² without the brake. Along its length of 58 mm, the shaft is 32 mm wide. The shaft has a fixing hole that is M10-sized built in. Using the Hiperface interface, the encoder is made to measure a single turn with an accuracy of one revolution. It has a precision of 16 signal periods. The bolt circle is 165 mm in diameter, which ensures that the fixing is stable. The brake is made to fit a size 2 wheel, and the motor self-cools, so it works well. An angle connector M23 that can be rotated makes the electrical link.

The MS2N07-D0BHN-ASUK2-NNNNN-NN servo motor further incorporates a spigot dimension of 130 mm and a shaft length of 58 mm that ensures precision alignment and stability during operation. The encoder design supports one revolution absolute positioning that allows accurate feedback for motion control. These features enable reliable integration into automation systems and ensure consistency in positioning accuracy. The motor specifications demonstrate a balanced combination of speed and inertia that supports demanding drive applications.

Frequently Asked Questions about MS2N07-D0BHN-ASUK2-NNNNN-NN:

Q: Why does MS2N07-D0BHN-ASUK2-NNNNN-NN use a 32 mm shaft?

A: The 32 mm shaft ensures mechanical strength that supports higher torque transmission. It provides stability for precision drive systems that require durable and accurate coupling.

Q: Does MS2N07-D0BHN-ASUK2-NNNNN-NN benefit from low rotor inertia?

A: Yes, low rotor inertia provides faster acceleration and deceleration. It improves dynamic response in automation systems that require frequent changes in motion and positioning.

Q: Why does MS2N07-D0BHN-ASUK2-NNNNN-NN include a shaft seal?

A: The shaft seal prevents dust or oil entry. It ensures durability and stable motor operation that maintains performance under continuous load conditions.

Q: How does MS2N07-D0BHN-ASUK2-NNNNN-NN achieve accurate positioning?

A: The motor integrates a single-turn absolute encoder. It transmits precise angular position within one revolution that ensures high accuracy in feedback-controlled drive systems.

Q: Do MS2N07-D0BHN-ASUK2-NNNNN-NN motors require external cooling?

A: No, the product features self-cooling. However, torque output increases from 22.0 Nm to 28.2 Nm when external cooling is applied under 100k operating conditions.
