Product Description:

The MS2E03-D0BYN-CMSK1-NNNNN-NN is a three-phase permanent-magnet servo motor produced by Bosch Rexroth Indramat for the MS2E Synchronous Servomotors series. Intended for closed-loop positioning and velocity control in pick-and-place stations, feeders, and handling modules, the motor translates commanded current from a servo amplifier into tightly regulated mechanical rotation. By combining permanent-magnet excitation with a compact frame, it fits automated equipment where cycle time and positioning accuracy affect overall throughput.

At the electrical interface, the motor attains a nominal speed of 9,000 rpm under rated load. A single-cable M23 connector carries power and ACUROlink feedback, minimizing wiring and allowing the plug to rotate for strain relief. The multi-turn encoder delivers a 20-bit single-turn resolution and an absolute range of 4,096 revolutions, so the drive retains position information after a power loss. The IP65 enclosure blocks dust and resists water jets, while a PT1000 temperature sensor reports winding temperature to the controller. Operation is permitted from 0 °C to 40 °C without derating and at altitudes up to 1,000 m. Heat is removed through self-cooling across the RAL 9005 varnished surfaces, eliminating the need for forced-air or liquid cooling. Deep-groove ball bearings support the low-inertia rotor, and frame length D corresponds to the 03 size code.

Mechanical installation uses a B5 / IM3001 flange. Its face measures 58 mm, with a 63 mm hole circle and 4.5 mm mounting bores for direct attachment to gearboxes or machine plates. A 40 mm centering collar helps limit axial runout and supports accurate alignment at the mounting interface. The motor has a keyway shaft with a shaft sealing ring, providing positive torque transfer while helping prevent contaminants from reaching the bearings. A size 1 brake supplies 1.80 Nm of holding torque when power is removed, helping secure stationary loads. The RAL 9005 coating protects the housing from ambient contamination encountered in industrial machinery. Its ATEX compliance permits installation in approved zones where explosive dust or gas may be present. Standard flange accuracy helps maintain mechanical alignment between the motor, coupling, and connected equipment during operation.
