Product Description:
The MSK101E-0300-NN-S2-AG0-RNNN synchronous servomotor is manufactured by Bosch Rexroth Indramat and belongs to the MSK IndraDyn S Synchronous Motors series. It is intended for industrial automation axes where controlled rotation, repeatable positioning, and rapid speed changes are required. The integrated optical encoder delivers real-time shaft data to the drive, letting the motor close precise feedback loops that keep conveyors, gantries, or tool spindles aligned with the programmed motion profile. In closed-loop operation, the drive can use this feedback to correct small speed and position deviations as the load changes during acceleration, deceleration, and steady running.
This model uses natural convection for thermal management, so its housing releases heat to ambient air without fans. Position feedback travels over an EnDat2.1 interface, and the sensor inside the motor counts 2048 signal periods per revolution to provide fine commutation data. The feedback remains phase-aligned with the drive through a single cable, and power exits through the A-side connector. An IP65 enclosure blocks dust and water jets, while continuous duty is allowed in 0–40 °C ambient conditions. A plain shaft mates directly to belts, couplings, or gears without a keyway that might create imbalance.
The rotor and stator have increased concentricity, which lowers radial runout and helps the optical sensing system maintain accuracy. The encoder is a single-turn type, so position is reported within one revolution. The electromagnetic circuit follows winding code 0300, which matches drive tables for torque-current scaling, while Thermal Class 155 insulation supports sustained copper temperatures during repetitive duty. Mechanical proportions correspond to motor size 101 with the E length variant, which provides added active iron without changing the mounting pilot. The assembly is delivered without a holding brake, and the A-side power connector simplifies routing in cabinets that place cable glands toward the machine base.
Frequently Asked Questions about MSK101E-0300-NN-S2-AG0-RNNN:
Q: What type of encoder and resolution does the MSK101E-0300-NN-S2-AG0-RNNN motor use?
A: The MSK101E-0300-NN-S2-AG0-RNNN uses an optical EnDat2.1 encoder with 2048 signal periods for precise position feedback.
Q: How is the MSK101E-0300-NN-S2-AG0-RNNN motor cooled?
A: This motor dissipates heat using natural convection cooling, operating efficiently without forced air or liquid cooling systems.
Q: What is the protection rating of the MSK101E-0300-NN-S2-AG0-RNNN, and what does it mean?
A: The protection rating of this motor is IP65, making it resistant to dust and low-pressure water jets.
Q: Does the MSK101E-0300-NN-S2-AG0-RNNN motor have a holding brake?
A: This model does not include a holding brake, so it will not provide brake-based position holding when power is off.
Q: What shaft type is featured on the MSK101E-0300-NN-S2-AG0-RNNN motor?
A: The shaft type of this motor is plain, which provides smooth torque transmission without a keyway or other mechanical features.
