Product Description
One of the components of the Rexroth IndraDrive drive system is the MSK servo motor. The motors in this series are compact units with a high torque density. They are available in various sizes and have a wide power spectrum. The MSK motors are used as rotary main and servo drive motors in applications such as machine tools, robotics, metal-forming machines, packaging and food-processing machines, and printing and paper-processing machines.
The MSK070E-0450-NN-M2-UP0-RNNN is an MSK servo motor model designed and manufactured by Bosch Rexroth. It is a self-cooling servo motor that utilizes natural convection for heat dissipation. The motor encoder in this model is a multiturn absolute encoder with the EnDat 2.1 interface. This encoder provides the necessary signals to the drive controller to control the motor’s speed and detect its position. Thanks to its optical measuring principle, it can perform this function with a high level of precision and has a system accuracy of ±80 angular seconds. This MSK motor can also be equipped with fan units for continuous operations with high repetition rates.
Using a plain shaft with a shaft sealing ring, a non-positive shaft-hub connection with zero-backlash can be achieved on the MSK070E-0450-NN-M2-UP0-RNNN. It also ensures that the motor can be operated with minimal noise. Its maximum speed is 6,000 revolutions per minute, and the maximum current for its operation is 57.9A. There are six pole pairs in this MSK synchronous motor, and its rotor has a moment of inertia of 0.00458 kgm2. Its Ingress Protection rating is IP 65 according to EN 60529, indicating that it is touch-proof, dust-proof, and impervious to water jets from all directions.
