Product Description:

The MS2E05-B0BTN-CMSK1-NNNNN-NN is a three-phase permanent-magnet servo motor produced by Bosch Rexroth Indramat for the MS2E Synchronous Servo Motors series. It supplies finely regulated torque and speed to positioning tables, tool spindles, packaging axes, and other automated equipment where repeatable motion is essential. The motor converts drive commands into responsive rotary motion and supports rapid acceleration, controlled deceleration, and stable positioning under changing loads. Its compact design allows it to serve applications that require high dynamic performance without occupying excessive machine space.

The motor reaches a nominal speed of 6000 rpm, supporting fast indexing and short production cycles with its low-inertia rotor. Precise feedback is delivered by the Advanced Performance ACUROlink system, which provides a functional single-turn resolution of 20 bits and tracks absolute position across 4096 mechanical turns. The enclosure has an IP65 protection rating and includes a shaft sealing ring, preventing dust and directed water jets from entering the housing. The design is ATEX compliant, supporting installation in applicable hazardous areas, while the RAL 9005 varnish finish resists common industrial fluids. A rotatable M23 single-cable connector carries power, encoder, and brake conductors through one shielded lead, reducing the number of separate cable runs required between the motor and drive.

The motor uses a B5 / IM3001 mounting interface, and its size 1 electrically released brake supplies a holding torque of 10.00 Nm. The centering collar has a diameter of 95 mm, while the square flange measures 98 mm and includes 9 mm mounting holes arranged on a 115 mm pitch circle. This mounting arrangement supports rigid attachment to compatible gearheads, machine frames, and positioning assemblies. Operation is permitted from sea level to 1,000 m above mean sea level without power derating, and the ambient operating temperature can range from 0 °C to 40 °C under the same condition. A PT1000 sensor monitors stator temperature, while deep-groove ball bearings support the keyed shaft during radial loading and repeated speed changes. The self-cooling aluminum frame dissipates motor heat without requiring external fans or auxiliary heat sinks.
