Product Description:

The MSK101E-0450-NN-M2-AG0-RNNN is an IndraDyn S synchronous servomotor from Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. Designed for closed-loop motion axes, the unit converts drive current into precisely controlled torque and speed, enabling position, velocity, and force regulation in automated packaging, printing, and material-handling lines. It connects directly to IndraDrive controllers and suits machine-mounted assemblies where sealed construction and compact dimensions are required.

Cooling by natural convection lets the stator shed heat without fans or liquid lines, so installation clearance becomes the main thermal factor. The rotor and stator geometry is arranged for increased concentricity, which helps reduce radial runout and supports smooth torque in the 101 frame. Feedback comes through an EnDat2.1 optical encoder that issues 2048 signal periods per revolution, and interpolated counts support fine velocity loops. The motor has an IP65 enclosure, and the plain shaft is made of stainless steel for use in wash-down areas. Power exits on the A-side, which can help shorten cable routing, and winding code 0450 matches the electrical values used by IndraDrive amplifiers for medium-torque axes.

The encoder is classified as Multiturn Absolute, so the drive can retain position information after power cycles. Because the unit is supplied without a holding brake, the load must be held by external locking or by drive-generated torque when the axis is stopped. Thermal behavior follows insulation class 155, which permits winding temperatures up to 155 °C when the motor is matched correctly to its duty cycle. Continuous operation is limited to an ambient range of 0–40 °C, so the surrounding air must stay within that window. The E length variant helps fit installations that have limited mounting depth.
