Product Description:

The MSK071D-0450-FN-M1-UP2-NNNN is a synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Within an automation cell, this motor converts controlled electrical power into rotary motion for indexing tables, gantry axes, or spindle functions. Its standard D length and 071 frame size place it in the mid-range of the series, balancing continuous torque output with a compact footprint. In closed-loop systems, it works with a servo drive to deliver tightly controlled speed, torque, and position during repeated machine cycles. This makes it suitable for coordinated axes that require fast response and stable motion under changing loads. The unit’s electrically released holding brake keeps driven loads stationary whenever power is removed from the drive.

This design uses the FN cooling configuration, so the stator jacket must be supplied with coolant, and the built-in channel supports liquid cooling to keep winding temperature within the insulation limit. Position data travel to the controller over a rotatable 240° connector that hosts the optical encoder using the Hiperface interface. That encoder generates 128 signal periods per mechanical revolution and stores multi-turn absolute information, enabling immediate commutation after startup. The rotatable connector also helps route cables in tight machine spaces and reduces strain at the motor interface. An enclosure rating of IP65 seals the housing against dust ingress and water jets, permitting mounting outside a protected cabinet. During power-off, the electrically released brake develops 30 Nm of static holding torque to secure vertical or load-bearing axes.

The motor operates in ambient temperatures from 0 to 40 °C, so it fits most factory environments without additional derating. Thermal class 155 insulation supports continuous operation at elevated winding temperatures without premature aging. Mechanical coupling uses a shaft with keyway, which provides positive torque transmission to gears, pulleys, or couplings. This arrangement supports secure coupling to transmission components in applications that require precise load transfer. The winding code 0450 indicates the motor’s electrical impedance and current profile for use with matching IndraDrive power stages. Matched electrical data help the drive regulate current smoothly during acceleration and steady-state operation.
