Product Description:
The MSK101D-0300-NN-M1-RP2-NNNN is a synchronous motor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. In automated machinery, it provides precise rotary positioning and speed regulation so servo drives can follow programmed motion profiles with minimal lag. The motor uses the 101 frame size with D length, and winding code 0300 is intended for compatible IndraDrive amplifiers. Its synchronous design supports accurate response during steady-speed operation and rapid position changes. This arrangement suits handling, indexing, and other servo axes that need repeatable motion over frequent start-stop cycles.
This model uses natural convection cooling, so heat leaves through the housing surface without forced airflow. Feedback is handled through a Hiperface interface that exchanges absolute position data and motor information with the drive over a bidirectional serial channel. The optical encoder provides 128 signal periods per revolution, and its multiturn absolute design retains revolution counts after power is removed. Absolute feedback lets the drive read rotor position immediately after startup. An electrically released holding brake supplies 70 Nm of static torque to keep the load stationary when the drive is disabled. The housing is rated IP65, which helps protect internal components from dust and low-pressure water jets during normal operation. Power enters through a right-side connector, which supports clean cable routing on machines with limited mounting space.
The motor uses a shaft with keyway for torque transfer to couplings and pulleys commonly used on handling axes. A keyed shaft also helps maintain positive mechanical engagement where slip cannot be tolerated. Insulation class 155 allows high winding temperatures during continuous operation, supporting demanding acceleration and deceleration cycles when the drive is set correctly. Reliable operation is intended within an ambient temperature range of 0 to 40 °C, so the installation area must stay within that span. Ambient air outside that range can increase thermal stress during long duty cycles.
