Product Description:

The Bosch Rexroth Indramat MSK100B-0450-NN-M1-RG0-NNNN belongs to the MSK IndraDyn S Synchronous Motors series. As a synchronous servomotor, it translates commanded current from a drive into precise torque and speed for positioning axes in automated machinery. The model is delivered in a standard housing with size 100 frame dimensions, allowing direct mounting to reducers, ball screws, or toothed belt pulleys in packaging, printing, and material-handling equipment. Its size also suits machinery that needs a balance between torque capability and installation space. This layout supports servo-controlled motion where repeatable acceleration and accurate positioning are required throughout automated cycles.

Heat is removed through natural convection, so no external fan or liquid circuit is required. The enclosure carries an IP65 rating, protecting the stator and encoder electronics from dust and low-pressure water jets. Rotor position is measured by an optical encoder that communicates through the Hiperface interface, and its code disk provides 128 signal periods per revolution. The multiturn absolute feature preserves turn count without auxiliary batteries, so the drive can retain position information across power interruptions. The motor is supplied without a holding brake, so static loads must be supported by drive torque or external locking devices. Motor length code B pairs with winding code 0450 for the electromagnetic package and rated torque characteristics.

The power connector is oriented on the right side of the frame for streamlined cable routing inside compact cabinets. A plain shaft transfers torque through clamp couplings or shrink discs without keyway stress points. Continuous duty is specified for ambient temperatures from 0 to 40 °C, and class 155 insulation permits elevated winding temperatures during demanding cycles. This shaft style is commonly used where smooth coupling surfaces are preferred, and the connector position helps keep cable bends controlled near the motor. The connector placement can also simplify routing where nearby guards, panels, or machine members limit available cable entry space.
