R911315325 (MSK100B-0300-NN-M2-AG0-RNNN)

Description

The MSK series of synchronous servo motors created by Bosch Rexroth, specifically the R911315325 (MSK100B-0300-NN-M2-AG0-RNNN) model, is versatile, compact and highly durable. Its wide power spectrum, compact design and high torque density make it suitable for a variety of applications. The motor shields itself from thermal overload with an inbuilt KTY84 thermal sensor and relies on natural convection for heat dissipation. The output shaft, which requires clamping sets or elements for coupling, operates with minimal noise and backlash, adhering to DIN 42955 standards for reduced shaft run-out and axial run-out. At 20oC, the winding resistance is 0.43 Ohms, and the voltage constant is estimated at 108.5 V/min-1. With a maximum speed of 4,500 RPM, its bearing lifespan is about 30,000 operating hours when respective radial and axial loads are maintained. The motor is also resistant to intrusion by foreign objects or water sprays with its IP 65 rating. The motor uses an optical EnDat 2.1 encoder that allows for multiturn readings.
