The R911323951 (MSK101E-0300-NN-M1-BP3-NNNN) is a high-performance servo motor from the IndraDyn S MSK series, typically utilized within drive systems such as the Rexroth IndraDrive and suitable for a variety of applications including robotics, metal-forming, machine tools, and food processing machines. This self-cooling motor leverages natural convection for efficient heat dissipation. It includes a multiturn Hiperface optical encoder that tracks and records the rotor's absolute position across 4,096 mechanical rotations, retaining this information even after a power-down. It also has an onboard memory for parameter storage. The motor features an electrically-released holding brake (24V rated voltage, 120Nm holding torque) for secure positioning after deactivation. Equipped with a shaft sealing ring and keyway as per DIN 6885-1, the output shaft is resistant to oils and chemicals. The motor operates at a maximum speed of 4,600 RPM and torque of 231.0Nm. Embodying four pole pairs, it meets the IP 65 protection category as per EN 60529.
