Product Description:

The MS2E04-C0BTN-CSSG0-NNNBN-NN is a three-phase permanent-magnet servomotor from Bosch Rexroth Indramat that belongs to the MS2E Synchronous Servomotors series. Under digital drive control, it produces synchronous torque for controlled motion in industrial machinery. Designed for closed-loop position and velocity tasks, the motor integrates into drive axes where quick acceleration and accurate feedback are required for packaging, assembly, or pick-and-place stations.

During operation, the motor reaches a nominal speed of 6000 rpm, supporting high cycle rates in fast-moving axes. Position feedback is delivered by the Advanced Performance ACUROlink single-turn encoder, which has a functional resolution of 20 bits and measures absolute position within one revolution. A single rotatable M23 cable connection carries power and data, reducing the amount of wiring required between the motor and drive. For installation, the housing uses a B5 / IM3001 mounting pattern with an 82 mm flange, a 50 mm centering collar, a 95 mm bolt circle, and 6.6 mm mounting holes. The IP65 enclosure protects internal components against dust and water jets when the motor is installed correctly.

The motor operates in ambient temperatures from 0 to 40 °C without derating, while its self-cooling design transfers heat through the varnished RAL 9005 housing. A smooth shaft with a shaft sealing ring transfers torque to a compatible coupling and helps prevent contaminants from reaching the internal bearings. Deep-groove ball bearings support the rotor, while a PT1000 sensor monitors winding temperature during operation. The motor is supplied without a holding brake, so an external mechanism or drive-generated torque must secure static loads. Fast response is supported by the low-inertia rotor, which reduces the effort required for acceleration and deceleration. The size 04 frame and length code C provide a compact housing while maintaining suitable power density for automated motion axes. Standard flange accuracy supports precise alignment, and the motor can be installed at altitudes up to 1,000 m under its stated operating conditions.
