Product Description:

The MSK100A-0450-NN-M2-BG0-RNNN is a synchronous servo motor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It converts drive-controller commands into precise rotary motion for positioning, packaging, and material-handling axes in automated systems. In closed-loop operation, the motor supports controlled acceleration, stable speed regulation, and repeatable positioning during frequent start-stop cycles. This makes it suitable for axes that must synchronize motion with conveyors, feeders, or indexing devices. The motor belongs to the 100 mm frame class, which gives it a compact housing for medium-duty axis applications where installation space is limited.

Its thermal management relies on natural convection, so heat is dissipated through the housing without forced air or liquid circuits. This cooling method keeps the motor layout simple and avoids the extra hoses or fan assemblies used on more heavily cooled designs. Rotor position is reported through an EnDat2.1 feedback system that sends absolute position data over a bidirectional serial link. The encoder provides 2048 signal periods per revolution and uses an optical scanning principle for stable feedback quality at low speed. The feedback channel also supports accurate commutation and immediate position availability at startup. Because it is a multiturn absolute system, the controller can retain position information across multiple shaft revolutions after power-up without a homing move.

The motor uses an increased concentricity design to minimize runout, which helps reduce stress on couplings and connected gear stages. It has a frame size of 100 and winding code 0450, which correspond to the electrical and mechanical format used with compatible IndraDrive amplifiers. A plain shaft exits the A-side without a key, which supports clamp-style couplings and smooth torque transmission. Power is connected through a B-side connector, which can simplify cable routing in compact machine layouts. The motor is supplied without a holding brake, so vertical or suspended loads need external holding force when power is removed.
