Product Description:

The MSK101C-0450-NN-M1-AP2-NNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. It is installed in automation axes that demand precise position and velocity control and pairs with IndraDrive amplifiers through its integrated multi-turn optical encoder to provide closed-loop feedback for coordinated motion. This arrangement lets the drive track rotor movement continuously, which supports accurate positioning, steady speed regulation, and repeatable response during changing load conditions.

Cooling is handled by natural convection, so installation must leave enough free surface area for heat to dissipate from the housing. The enclosure meets the IP65 rating, guarding internal windings against dust and low-pressure water jets during routine cleaning. Position data is exported over a Hiperface interface, and the optical encoder provides 128 signal periods so the connected drive can interpolate finer increments for smooth motion. An electrically released brake supplies 70 Nm of static torque, holding the shaft when the power stage is disabled. The motor also has a standard mechanical design, a size 101 frame, a length C body, and an A-side power connector.

The motor’s windings use insulation class 155, permitting continuous duty within an ambient range of 0–40 °C under the stated operating conditions. The motor uses winding code 0450, which matches the voltage and current characteristics intended for this frame size. Torque is transmitted through a shaft with keyway, providing positive engagement with pulleys or couplings and helping prevent slip under load. The feedback system retains absolute position across 4096 revolutions, so the axis can return to operation without a homing cycle after a power interruption. A standard flange pattern supports mounting on compatible machine interfaces.
