Product Description:

The MSK100A-0300-NN-M2-LG0-RNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It is intended for closed-loop motion axes where high positional accuracy is required. The motor combines size 100 stator laminations, an A-length active stack, and winding code 0300 to support a torque-speed range suited to mid-range conveyors, indexers, and forming equipment. Its synchronous design allows the drive to regulate shaft speed and position with tight response during repeated start-stop cycles. This frame is often used on packaging, transfer, and indexing equipment that needs repeatable motion without a large motor body.

Heat generated in the stator is removed by natural convection, so the motor can be mounted without forced-air hardware when load cycles stay within the rated range. Rotor position is captured by an optical measuring system with EnDat2.1 serial feedback at 2048 signal periods per revolution, giving the drive precise incremental and absolute data. The optical principle helps reduce the effect of electrical noise during fine positioning and low-speed control. An IP65 housing helps protect internal parts from dust and low-pressure water jets, while the plain shaft supports direct coupling to gearboxes or belt pulleys. The increased-concentricity design reduces radial runout for smoother rotation.

For restart tracking, the encoder stores revolutions with a multiturn absolute reference, allowing the control system to retain position information after power loss. The motor is delivered without a holding brake, so vertical or suspended loads must be secured by external hardware or continuous drive torque. Permissible ambient operating temperature is 0 to 40 °C, which suits standard industrial machine environments. Power and protective earth enter through a connector on the left side, which can simplify cable routing where installation space is limited. The winding uses class 155 insulation, allowing elevated internal temperatures without early insulation breakdown.
