Product Description:

The MSK100C-0300-NN-M2-AG2-RNNN is an IndraDyn S synchronous servomotor built by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It supplies precisely regulated torque and velocity for axis control in industrial automation where coordinated motion and repeatable positioning are required. The motor supports closed-loop motion on transfer systems, handling units, and other automated axes that demand smooth speed changes. Its synchronous design allows the paired drive to maintain accurate response during acceleration, deceleration, and holding.

This motor is cooled by natural convection, so enclosure airflow must be sufficient to dissipate losses without auxiliary fans. Rotor and stator machining follow an increased concentricity design that minimizes radial runout during rotation. Position feedback is provided through an optical encoder that communicates over the EnDat2.1 interface and delivers 2048 signal periods per revolution. Its multiturn absolute capability retains shaft position information across power cycles. The electrically released brake holds the shaft with 70 Nm when de-energized, helping prevent drift on vertical axes. Winding code 0300 identifies the electrical winding set, and the A-side power connector supports straightforward cable routing. Operation is permitted at ambient temperatures from 0 °C to 40 °C.

An external seal system is unnecessary because the housing achieves IP65 protection against dust ingress and water jets. The mechanical geometry follows motor size 100, and the active body uses motor length C to provide the magnetic stack required for the installed winding. Power is transmitted through a plain shaft, which eases coupling to gearboxes or belt pulleys in machines that use simple hub connections. The insulation system is rated to class 155, allowing continuous winding temperatures up to 155 °C without thermal degradation. The housing depth must match the C-length body when space is allocated inside the machine.
