The Bosch Rexroth synchronous servo motor R911383111 (MSK101D-0450-FN-M2-AG2-RNNN) is configured for high-precision motion applications and features a liquid-cooled stator with an FN cooling requirement. The motor size is 101 with length D and utilizes an optical multiturn absolute encoder (EnDat 2.1, 2048 signal periods). The encoder accepts 3.6–14 VDC, with a maximum current draw of 250 mA. It includes an electrically-released holding brake rated at 70 Nm. The shaft is plain and sealed, designed for increased concentricity. Electrical power is supplied via the A-side connector. Key specifications include a continuous standstill current of 50.6 A, continuous standstill torque of 57.0 Nm, maximum current of 187.7 A, maximum torque of 160.0 Nm, and winding inductivity of 1,700 mH. Liquid cooling requires a minimum flow of 2 L/min through a dedicated duct. Only qualified personnel should perform installation and operation.

Frequently Asked Questions

Why is an electrically released brake used on the MSK101D-0450-FN-M2-AG2-RNNN motor?

The MSK101D-0450-FN-M2-AG2-RNNN motor brake holds the shaft when power is removed or during emergency stop conditions. It ensures zero drift under torque loads up to 70 Nm.

How does winding inductivity 1,700 mH influence current dynamics?

The higher inductivity slows the rate of current change, smoothing current spikes and reducing electrical noise. It also impacts the servo drive tuning and current control bandwidth.

Why is EnDat 2.1 chosen as encoder interface in this servomotor

The EnDat 2.1 provides highly accurate, bidirectional absolute position feedback and calibration data over a robust digital link. It supports multiturn capability and error correction.

What is a typical application of the MSK101D-0450-FN-M2-AG2-RNNN motor in industry?

The MSK101D-0450-FN-M2-AG2-RNNN motor is used in robotics or CNC systems which ensures smooth, fast interpolated motion and accurate path tracking. Its high peak torque and feedback enable tight motion loops in machine tools.

How does the servo handle ambient temperature and cooling constraints?

The design limits ambient temperature to ≤ 40 °C and recommends coolant inlet temperature ~5 °C below ambient to prevent condensation. Excessive ambient heat reduces available continuous torque.
