Product Description:

The MS2E07-C0BQN-CMSG1-NNNBN-NN is a three-phase permanent-magnet servomotor produced by Bosch Rexroth Indramat within the MS2E Synchronous Servomotors series. As a closed-loop drive element, it pairs with Rexroth inverters to deliver precise position and speed control for axes in packaging machines, pick-and-place gantries, and electronic assembly cells. A low-inertia rotor supports fast acceleration and responsive changes in speed. The smooth shaft allows direct coupling to gearboxes or belt pulleys in clean, dust-protected environments.

The motor reaches a nominal speed of 4000 rpm, enabling high cycle rates while remaining within its intended operating range. An integrated brake supplies a holding torque of 20.00 Nm to secure vertical loads when power is removed. Position feedback comes from an ACUROlink multi-turn encoder that offers a 20-bit single-turn resolution and tracks up to 4096 revolutions, allowing absolute positioning across extended travel. The housing has an IP65 protection rating, which prevents dust ingress and resists low-pressure water jets. A shaft sealing ring helps prevent lubricant loss and protects the bearing area during continuous operation.

A single-cable connection with a rotatable M23 plug carries power, brake supply, and encoder signals, reducing the amount of wiring routed through the machine. The centering collar measures 130 mm for accurate alignment with B5 / IM3001 flanges, while the 11 mm mounting holes accept standard metric fasteners. Internal heat is removed by a self-cooling design, so no external blower is needed at ambient temperatures up to 40 °C or installation altitudes up to 1000 m. The brake is electrically released, eliminating drag during motion and supporting controlled emergency stops. A built-in PT1000 temperature sensor monitors winding temperature and supplies thermal data to the drive for derating or shutdown functions. Deep-groove ball bearings support the rotor, and a RAL 9005 varnish coating protects the exterior housing from normal industrial exposure.

Internal Product Review

  • ‘‘The MS2E07-C0BQN-CMSG1-NNNBN-NN is a 3~ PM motor from the MS2E synchronous servomotor line, and the self-cooling design is well suited for streamlined machine builds. The Advanced Performance ACUROlink encoder system with 20-bit singleturn resolution gives the feedback package a very precise, high-end feel in positioning applications. IP65 protection with a shaft sealing ring and low rotor inertia make this motor especially attractive for fast, demanding servo axes.’’
