Product Description:
The MS2E05-B0BTN-CMSK0-NNNNN-NN is a three-phase permanent-magnet synchronous servo motor manufactured by Bosch Rexroth Indramat for the MS2E Synchronous Servomotors series. Designed for precise motion in industrial automation, it delivers controlled torque and speed to packaging stations, pick-and-place axes, and similar equipment. A rotatable M23 single-cable connection carries power and feedback signals between the motor and drive, reducing the amount of machine wiring and allowing the cable outlet to be adjusted for the installation. The motor has a low-inertia rotor that supports responsive acceleration and deceleration during dynamic operating cycles.
The motor operates at a nominal speed of 6,000 rpm, which is also its maximum permitted speed. Its peak current is 16.8 A, providing the electrical capacity required for brief periods of rapid acceleration. The rotor produces a maximum torque of 11.5 Nm at 20 °C to overcome process inertia during short load peaks. The winding inductance is 14.09 mH, which affects current rise time and control-loop response. An Advanced Performance ACUROlink encoder provides a 20-bit single-turn resolution, while its multi-turn section retains absolute position information across multiple shaft rotations. The motor uses self-cooling and includes a PT1000 temperature sensor for winding temperature monitoring. It is suitable for operation from 0 °C to 40 °C and at elevations up to 1,000 m without derating, and its ATEX compliance supports use in designated hazardous areas.
The motor continuously supplies a standstill torque of 3.75 Nm at a winding temperature rise of 60 K, allowing it to hold a stationary load while energized despite having no integrated brake. Its mass is 4.0 kg, and the housing uses a 95 mm centering collar for alignment during mounting. The enclosure has an IP65 protection rating, while the shaft sealing ring helps retain lubricant and prevent dirt or low-pressure water jets from reaching the bearings. The encoder tracks up to 4,096 absolute revolutions, allowing the drive to recover the shaft position after a power interruption. The motor also has a 98 mm B5/IM3001 flange, a 115 mm bolt circle, and holes for 9 mm mounting bolts. Its frame has size code 05 and length code B, and the output uses a keyway shaft with a sealing ring. Deep-groove ball bearings support the shaft, while black RAL 9005 varnish protects the housing exterior. The mounting interface is manufactured with standard flange accuracy.
