Product Description:

The MSK101C-0300-NN-M2-RP0-RNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. It is intended for high-precision positioning in automated lines, where drive current is converted into accurate rotary motion for closed-loop axis control. Its increased concentricity helps reduce runout at the coupling, and the fan-free design supports installation in compact machine layouts where low maintenance and precise feedback are important.

The motor uses natural convection for cooling, so no external blower or liquid circuit is required to remove heat from the stator surface. Its IP65 housing helps block dust ingress and resists low-pressure water jets, allowing installation on machine frames without an added enclosure. Position data are transmitted through the EnDat2.1 interface, which supports bidirectional communication between the optical encoder and the drive controller. The encoder provides 2048 signal periods, giving the controller fine resolution for speed and position regulation. Mechanical power is delivered through a shaft with keyway, which helps couplings or pulleys stay secure under cyclic torque. The power connection is located on the right side, and the motor comes without a holding brake for applications that use external load-holding devices.

The encoder also supports multiturn absolute position storage, so rotational position can be retained after a power interruption. Frame code 101 identifies the motor size used for medium-power servo axes that need a balance of torque and inertia. Continuous operation is permitted in ambient temperatures from 0 to 40 °C, which suits common industrial environments. The winding insulation uses class 155, allowing the motor to tolerate internal hot-spot temperatures up to 155 °C under rated operating conditions.
