Product Description:
The MS2E07-C0BQN-CMSK1-NNNNN-NN is a three-phase permanent-magnet servomotor produced by Bosch Rexroth Indramat within the MS2E Synchronous Servomotors series. Designed for position-controlled axes in packaging, handling, and general automation, the motor converts drive commands into repeatable speed and torque while meeting ATEX conformity for use in zones that require equipment with limited surface temperatures. Its low-inertia rotor enables fast acceleration, and the built-in multi-turn feedback transmits absolute position data to the drive through a single-cable topology, simplifying installation in compact control cabinets.
The motor reaches a nominal speed of 4000 rpm, and its size 07 frame allows direct coupling to ball screws or timing pulleys without intermediate gearing. A size 1 permanent-magnet holding brake rated at 20.00 Nm secures vertical loads when the drive is disabled and releases electrically during motion. The motor is sealed to IP65 and fitted with a shaft sealing ring, so the housing prevents dust ingress and withstands low-pressure water jets during machine washdown. Motion feedback is generated by an ACUROlink multi-turn encoder that provides a single-turn resolution of 20-bit and tracks up to 4096 revolutions for absolute positioning after a power loss. The rotatable M23 connector carries power, brake, and digital feedback signals over one shielded hybrid cable.
Mechanical mounting follows the B5 / IM3001 pattern and positions the shaft with a centering collar measuring 130 mm in diameter. The square flange measures 140 mm across and has a bolt circle of 165 mm; standard flange accuracy and 11 mm holes accommodate metric fasteners. This geometry aligns the motor with gearboxes while keeping the frame length within code C. Continuous output is available from 0 to 40 °C and from sea level to 1,000 m above mean sea level without derating. Self-cooling removes operating heat without an external fan, while a PT1000 sensor monitors motor temperature. Deep-groove bearings support the rotor, RAL 9005 varnish protects the housing, and the keyed shaft provides positive engagement with a compatible coupling.
