Product Description

Bosch Rexroth’s MSK synchronous motors belong to the Indradyn S family and have numerous uses. These motors are characterized by compact construction, high dynamics, a high torque density, and an extremely high degree of precision due to new optical encoder systems. They are used as rotary main and servo drive motors in machine tools, printing and paper processing machines, food and packaging machines, metal forming machines, and robotics.

The high-precision encoder of the MSK101D-0300-FN-M2-BG0-RNNN is the multi-turn absolute encoder with the EnDat 2.1 interface. This encoder uses the optical measurement method and allows the recording of the motor's absolute, indirect position within 4,096 mechanical rotations. It has four pole pairs and a maximum speed of 4,600 revolutions per minute. The motor is equipped with a plain shaft which provides a non-positive, zero-backlash shaft-hub connection with a high degree of quiet running. It also has a unique design with reduced shaft run-out and axial run-out, according to DIN 42955.

Due to its liquid-cooling mechanism, the MSK101D-0300-FN-M2-BG0-RNNN is well-suited for extreme loads such as start-stop operations with high repetition rates. Its heat dissipation occurs over a coolant, released via a downstream heat exchanger to the downstream air. This MDD motor belongs to insulation class F; hence it has a high degree of thermal stability. Its protection rating is IP 65 according to DIN EN 60529, indicating that it has complete shock protection and is protected against the penetration of dust and damage from water jets. For optimal function, it should be operated at a maximum ambient temperature of 40°C and maximum relative humidity of 95%. Its maximum installation height is 1000m above sea level.
