The Bosch Rexroth MPN R911308353 (MSK071D-0450-FN-S2-UG2-RNNN) is an IndraDyn S synchronous servomotor equipped with a plain, low-backlash shaft and liquid cooling designated by Cooling FN. The unit features a singleturn optical encoder with 2048 signal periods, EnDat2.1 interface, and a rotatable connector (240°). The motor offers a continuous current of 17.6 A and torque of 20.0 Nm at standstill (100 K), with a maximum current of 69.3 A and maximum torque of 66.0 Nm. It includes a holding brake (electrically released, 30 Nm torque), increased concentricity design, and is housed in a black RAL 9005 casing to IP65 standard. Maximum axial load is 60 N, with a bearing service life of 30,000 hours, and incorporates a temperature sensor with an auto-shutoff at 150°C. Transport and storage require a horizontal position and emptying of liquid coolant. The B side employs a fixed bearing and the rotor integrates permanent magnets.

Frequently Asked Questions

How does liquid cooling benefit the motor during continuous operation?

The liquid cooling enables stable thermal management under heavy duty cycles. The feature allows higher torque output without overheating in compact machine spaces.

What role does increased concentricity design play in this motor?

The increased concentricity reduces radial runout and improves bearing life. The design enhances precision in high speed motion applications.

Why is an electrically released holding brake important in automation systems?

The holding brake ensures load retention when the drive is powered down. The brake prevents unintentional movement in vertical or safety critical axes.

How does a plain shaft simplify integration in machinery?

The plain shaft provides flexible coupling with various transmission systems. The design eases alignment and reduces installation complexity.

What installation advantage does the rotatable 240° encoder connector provide?

The connector rotation supports diverse cable routing in tight enclosures. The adjustment helps reduce mechanical strain on cabling.
