MS2E05-B0BTN-CMSK0-NNNNN-NN
MS2E Synchronous Servomotors
The MS2E05-B0BTN-CMSK0-NNNNN-NN is a three-phase permanent-magnet servomotor engineered by Bosch Rexroth Indramat within the MS2E Synchronous Servomotors series. Designed for precise positioning in industrial automation, the unit converts electrical commands from a drive controller into tightly regulated rotary motion for packaging stations, pick-and-place axes, and similar tasks. Its compact frame length code B and motor size 05 help machine builders achieve high dynamic response where mounting space is limited.
At the electrical level, the motor reaches a nominal speed of 6000 1/min, a figure that supports rapid indexing cycles while its low-inertia rotor maintains servo accuracy. Heat is removed through self-cooling, so no external blower or liquid circuit is required. The housing provides a IP65 protection class together with a shaft sealing ring, shielding the interior against dust and water. When explosive atmospheres are present the construction remains ATEX compliant, allowing installation in classified zones. Motion feedback comes from an Advanced Performance ACUROlink multiturn encoder that delivers 20-bit functional single-turn resolution for fine position granularity over the full revolution. Power and signal share a single rotatable M23 connector, simplifying cable routing and reducing enclosure penetrations.
Mechanical integration is guided by a centering collar diameter of 95 mm on a 98 mm flange with standard exactness, with a 115 mm hole circle and 9 mm mounting bores meeting the B5 / IM3001 pattern. The keyed, sealed shaft is supplied without a holding brake, so external restraint is needed when power is removed. A PT1000 sensor monitors winding temperature, while deep-groove ball bearings and a black RAL 9005 varnish promote long service life. For environmental planning the unit tolerates 0 … 40 °C ambient temperature, continuous duty up to 1000 m installation altitude, and the multiturn encoder tracks 4096 absolute revolutions without battery backup.
