Product Description:
The Bosch Rexroth Indramat MSK070D-0450-NN-M2-UP1-RSNN is an IndraDyn S synchronous servomotor in the MSK IndraDyn S Synchronous Motors series. Built in size 070 with an elongated D housing and winding code 0450, the unit serves as a high-precision rotary actuator in CNC stations, pick-and-place modules, and other automated axes that require rapid positioning and smooth speed control. It integrates with IndraDrive power stages and closed-loop feedback systems so torque, speed, and position can be regulated with high accuracy during demanding motion profiles. This layout suits machines that need repeatable motion, short response times, and stable operation during frequent start-stop cycles.
Its thermal management relies on natural convection, so no auxiliary fan is required and installation remains simpler in compact machine layouts. An IP65 enclosure helps keep out dust and water jets, while insulation class 155 allows the windings to operate at elevated temperatures before thermal derating begins. The optical multiturn absolute encoder communicates through EnDat2.1, and the connector can be rotated through 240° to ease cable routing in confined spaces. The encoder supplies 2048 signal periods per revolution, giving the drive fine feedback for precise positioning over multiple shaft turns.
An electrically released holding brake provides 23 Nm of static torque to keep vertical or indexing axes in place when power is removed. This helps prevent unintended movement during pauses or shutdowns. Motion is transmitted through a shaft with a keyway, which supports positive torque transfer to pulleys, couplings, or gears used in automated drive trains. The motor operates in ambient temperatures from 0 to 40 °C, making it suitable for enclosed industrial equipment that depends on passive cooling and stable feedback performance during starts, stops, and dwell periods.
