Product Description:

The MS2N10-E0BHA-CMAK0-NNNNN-NN servo motor manufactured by Bosch Rexroth Indramat is designed to function reliably and fulfill the electrical and mechanical requirements of automation systems. For accurate feedback, it has a multiturn design that counts 4096 absolute turns. 

The constant torque of the motor is 119.0 Nm when cooled from the inside or the outside. This makes sure that the torque stays the same at zero speed. The width of the flange is 196 mm. The motor is made for a strong mechanical mounting. The shaft is 80 mm long and has a width of 38 mm. The shaft of the motor has a keyway and a shaft seal. The servo motor uses a digital ACURO@link encoder with 20 bits. This type of encoder provides SIL2 and PL d safety levels. The MS2N10-E0BHA-CMAK0-NNNNN-NN servo motor has a maximum torque of 234.0 Nm and a maximum speed of 4000 rpm. The rotor's inertia of 0.0114 kg/m² indicates that it can move rapidly. The bolt circles have a width of 215 mm. The electrical link is made by an angle connector M58 on the A-side, which makes the wiring easier. The servo motor has forced air with an axial fan that runs on 230 V and keeps the cooling performance steady while it is in use.

The < weighs 46.5 kg and has an IP65 grade, which means it can work well even when it is exposed to dust and water jets. The spigot on the motor is 180 mm long and fits perfectly with the mounting face. The type of motor is made without a stopping brake. The motor can be used in automation lines that need consistent input on motion and mechanical balance.
