MS2E05-B0BTN-CMSK1-NNNNN-NN
MS2E Synchronous Servomotors
The MS2E05-B0BTN-CMSK1-NNNNN-NN is a servo unit within the MS2E Synchronous Servomotors series from Bosch Rexroth Indramat. Classified as a 3-phase permanent-magnet motor, it is intended to deliver rapid positioning and repeatable velocity in industrial automation cells. The model combines the high-resolution feedback of an integrated multiturn encoder with a low inertia rotor so drive controllers can execute tight motion loops in packaging, assembly, and semiconductor equipment.
This motor reaches a nominal speed of 6000 1/min, allowing short cycle times while the deep-groove ball bearings support continuous operation. The Advanced Performance ACUROlink system supplies a multiturn count of 4096 revolutions and a single-turn resolution of 20 bit, enabling fine position interpolation over the entire travel length. A holding brake rated at 10.00 Nm keeps vertical loads secure when the drive is de-energized and is released electrically to avoid residual drag. The single cable power and feedback line uses a rotatable M23 connector, simplifying routing and is identified as Single cable connection. Rotor dynamics are improved by the low inertia class, while the PT1000 sensor feeds accurate winding temperature data to the drive. Frame length code B and motor size code 05 define the compact envelope; varnish RAL 9005 coating and a standard flange exactness round out the internal design.
Mechanical integration follows the B5 / IM3001 pattern with a 98 mm flange, a 95 mm centering collar, a 115 mm hole circle, and 9 mm mounting holes. The shaft uses a keyway and a sealing ring, which together with the enclosure gives a protection level of IP65 with shaft sealing ring. Operation is approved from sea level up to 1000 m and within an ambient window of 0 … 40 °C without performance derating. The motor employs Self-cooling so no external blower is required, and its surface finish in varnish RAL 9005 resists ambient contaminants. The unit is ATEX compliant, supporting use in zones where explosive atmospheres can occur.
