Product Description:

The MSK101D-0450-FN-S3-AG0-NNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. This motor delivers rotary motion for closed-loop positioning, speed, and torque control in automated machinery and production cells. Its electromechanical design integrates with IndraDrive controllers to convert commanded current into precise shaft movement for conveyor indexing, packaging axes, or metal-cutting spindles. The motor is intended for applications that require repeatable acceleration, stable low-speed control, and accurate response to changing load conditions. This makes it suitable for synchronized servo axes where the drive must hold position precisely during indexing, contouring, or rapid speed changes.

The unit uses liquid cooling, allowing continuous torque output without exceeding thermal limits when installed in tight machine frames. A protection rating of IP65 seals the housing against dust ingress and low-pressure water jets during normal machine cleaning. The rotor uses a plain shaft, which supports low-backlash clamping hubs or couplings rather than keyed connections. Position feedback is transmitted over the Hiperface serial interface, and operation is permitted in ambient temperatures from 0–40 °C. Because heat is transferred through a coolant circuit instead of external airflow, the motor can be used where surrounding ventilation is limited.

The encoder provides 16 signal periods per revolution from a capacitive sensing element, and the feedback is limited to a single-turn cycle, so absolute position repeats after one full revolution. This feedback format is commonly used on axes that complete a reference move after startup before entering normal production. Class 155 insulation supports winding temperatures suited to long duty cycles, while winding code 0450 matches the electrical characteristics expected by compatible IndraDrive controllers. Motor size 101 with length code D balances stall torque and installation space, and the power connector is oriented on the A-side to keep cabling aligned with common machine layouts. The motor is supplied without a holding brake, so vertical or suspended loads need an external holding method when power is removed.
