Product Description:

The MSK101E-0450-FN-M1-AG2-NNNN is a servo motor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. In automated machinery, it provides closed-loop torque and position control for feed axes, tooling spindles, and transfer stations where high dynamic response is required. That makes it suitable for axes that must accelerate quickly, reverse direction often, and maintain accurate positioning under changing loads. The motor uses size 101 with length E, and winding code 0450 matches the electrical characteristics expected by compatible IndraDrive power sections.

This unit uses liquid cooling because the FN cooling arrangement routes coolant through internal channels to remove heat during continuous torque operation. Feedback is handled through a Hiperface interface that carries position data and drive-side supply for the optical system, and it provides 128 signal periods per mechanical revolution. The housing has an IP65 rating to resist dust ingress and low-pressure water jets during washdown. The sealed housing helps the motor operate in production areas where airborne debris and routine cleaning are common. Continuous operation is permitted from 0 to 40 °C. The design is standard, the power connector is on the A-side for cable routing parallel to the motor axis, and the motor has a plain shaft for direct coupling.

An electrically released holding brake provides 70 Nm of torque to hold stationary loads after power is removed. Position information remains available after power cycles because the motor uses a Multiturn absolute encoder, so the drive can retain revolution data without batteries. This arrangement is useful on vertical or indexing axes that must stop without drift between motion cycles. Insulation class 155 identifies the winding system thermal class and supports elevated internal temperatures before insulation aging accelerates.
