Product Description:

The MSK100A-0300-NN-M2-AG0-RNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat and assigned to the MSK IndraDyn S Synchronous Motors series. It converts drive controller current into precise rotary motion for positioning and speed control tasks in automated machinery. A design with increased concentricity keeps the rotor centered, which reduces radial runout and supports repeatable motion quality. This makes the motor suitable for axes that need stable rotation during repeated indexing and continuous-speed operation.

Heat produced by the stator is removed through natural convection, so the motor can be mounted without external fans when surrounding airflow is adequate. Position feedback is supplied by an encoder with an EnDat2.1 serial interface and optical scanning; the internal disk provides 2048 signal periods, and its multiturn absolute capability tracks shaft revolutions even when power is off. The motor uses a plain shaft without a keyway, which simplifies coupling in applications that rely on friction or shrink-fit joints. Winding code 0300 is paired with a size 100 stator core and compact length A to balance torque density against installation space. Power conductors enter on the A-side of the housing, allowing cables to follow the machine frame and keeping the connection path aligned with the motor body.

The housing has a protection rating of IP65, which seals it against dust ingress and low-pressure water jets during washdown. Continuous operation is allowed from 0 to 40 °C, and the winding insulation system meets class 155, so conductor temperatures may reach 155 °C without degrading varnish integrity. This temperature range supports normal service in enclosed machinery that uses passive cooling. The motor does not include a holding brake, so the axis must rely on drive torque or external clamping to remain fixed when power is removed.
