The Bosch Rexroth R911321430 (MSK100B-0300-NN-S1-AG1-NNNN) is an efficient synchronous servo motor belonging to the MSK series, primarily utilized as a rotary and servo main motor in factory automation setups. Known for its compact build and high torque density, it is featured with a precise optical encoder with system accuracy of ±80 angular seconds. This encoder facilitates faster start-up and safe adjustment to the drive controller by detecting and relaying absolute, indirect motor position within a mechanical motor rotation. The R911321430 (MSK100B-0300-NN-S1-AG1-NNNN) model can reach a nominal speed of 3000 RPM and generate an optimal torque of 102.0 Nm. Its b shaft with zero backlash enables a non-positive shaft-hub connection and is sealed to DIN 3760 – design A standards. The motor also consists of four pole pairs and a rotor with a moment of inertia of 0.01920 kgm2. Through natural convection, the motor ensures heat dissipation into the ambient environment. Additionally, it incorporates two temperature monitoring systems (a KTY84 thermal sensor and a temperature model) to prevent thermal overload damage. This motor model is also equipped with an electrically released holding brake.
