Product Description:

The MSK101D-0300-NN-M2-BP0-RNNN is a synchronous servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. This brushless AC unit converts electrical energy from a servo drive into precise rotary motion for positioning, contouring, and velocity control tasks on automated machinery. When paired with IndraDrive controllers, the motor supplies closed-loop torque and speed for pick-and-place arms, packaging lines, and woodworking axes. Its servo-controlled design supports repeatable acceleration and stable motion during changing load conditions.

With a frame size of 101, the motor provides a larger rotor diameter, while length code D extends the active stack for higher continuous torque. The internal stator uses winding code 0300, which matches the drive current rating and sets the back EMF constants. Operation relies on natural convection, so the housing dissipates heat without fans or liquid circuits. A rear-mounted power connector on the B-side keeps power wiring clear of the load end, and the housing is rated IP65 to protect the windings from dust and water jets. Feedback signals travel through the EnDat2.1 interface, providing synchronous position updates to the controller.

In applications that demand fine positioning, the optical measuring system resolves 2048 signal periods per mechanical revolution and stores absolute position data over multiple turns, eliminating homing cycles after power loss. This capability operates within an ambient range of 0–40 °C, avoiding thermal derating in standard factory environments. Stator insulation reaches class 155, supporting elevated winding temperatures during intermittent overloads. A shaft with keyway provides slip-free torque transfer to gears or pulleys. The encoder sends continuous position data to the drive so commanded moves can be tracked accurately during operation.
