Product Description:

The MSK101D-0450-NN-M2-BG0-RNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It is used in industrial automation to drive precision axes in packaging, handling, and metal-forming equipment. In closed-loop systems, the motor works with a compatible drive to convert commanded current into controlled rotary motion for positioning and speed-regulated tasks. Its synchronous design supports accurate velocity and position control on machines that require repeatable motion during indexing, forming, and transfer operations.

The motor relies on natural convection for thermal dissipation, so no external blower or liquid circuit is necessary when the unit is installed in free air. An EnDat2.1 interface links the integral optical encoder to the drive, and the feedback element resolves motion into 2048 signal periods per mechanical turn. Because the encoder is multiturn absolute, axis position is retained through power cycles without a homing routine. Power is supplied through a B-side connector for straight cable routing, and the IP65 enclosure helps protect the housing against dust and low-pressure water jets. Increased concentricity reduces shaft runout, which helps improve coupling accuracy and limit vibration in high-speed assemblies. Optical scanning keeps feedback signals stable at low speed and during direction changes, which helps the drive maintain smooth motion.

This model is supplied without a holding brake, so any static load must be secured by external means or servo torque. A plain shaft interface supports backlash-free clamp or collet couplings in applications that do not require a keyed connection. Continuous operation is permitted from 0 to 40 °C, and insulation class 155 helps keep winding temperatures within the allowed thermal range. The D-length housing and 101 frame size give the motor the installation depth and torque capacity needed for medium-to-large servo axes. The absence of a brake also reduces added rotor inertia, which can be useful where fast acceleration and deceleration are required.
