The MS2N04-D0BHN-CMSK1-NNNNE-NN servo unit belongs to the MS2N Synchronous Servo Motors series from Bosch Rexroth Indramat. It serves as the rotary actuator in coordinated motion systems, converting drive amplifier output into precisely controlled torque and speed. Integrated position feedback allows closed-loop regulation, so machine tools, pick-and-place gantries, or packaging stations can execute repeatable moves to the commanded angle. The unit fits the MS2N04 mechanical envelope and uses the series’ common mounting geometry, simplifying interchangeability across a multi-axis platform.
Electrical integration is streamlined by a Single cable connection M23, rotatable that carries power, feedback, and brake lines while allowing the connector to swivel toward the cable tray. Precision feedback is produced by the Advanced - 20-Bit, ACURO®Link interface working with a Multiturn - 4,096 revolutions absolute encoder, so the controller receives high-resolution position data across four thousand mechanical turns. The shaft reaches a rated speed of 2000 1/min, and the rotor’s Low inertia profile permits rapid acceleration for short indexing moves. Motor size designation MS2N04, frame length D, and standard flange exactness define the axial and radial mounting dimensions.
Thermal handling relies on Self-cooling; heat is dissipated through the housing without auxiliary blowers or coolant. A Standard varnish, RAL 9005 black coating protects the stator frame, and standard bearings support the B5 / IM3001 endshield that also houses a PT1000 temperature sensor. The load can be secured during power loss by the Size 1, electrically released brake. Torque is transmitted through a Keyway, with shaft sealing ring, which keeps lubricant out of the motor interior. An additional grounding connection lowers leakage currents, and the low-inertia rotor remains aligned by the standard flange exactness during dynamic reversals.
