Product Description:
Bosch Rexroth Indramat manufactures the MSK075E-0450-NN-M2-UG0-RNNN in the MSK IndraDyn S Synchronous Motors series. This IndraDyn S synchronous servomotor uses frame size 075 with length code E, which suits medium-power axes where installation space is limited. When paired with a compatible drive, it converts commanded current into controlled torque and speed for repeatable axis motion. Its plain shaft couples directly to pulleys or clamping hubs, and the motor is built with increased concentricity to reduce runout during rotary motion in positioning tables, conveyors, and robotic joints.
The motor dissipates heat through natural convection, so it can operate without external fans when air can circulate around the housing. A rotatable encoder connector at 240° helps route cabling away from moving machine parts and reduces cable strain in tight installations. Position feedback is transmitted through the EnDat2.1 serial interface, and the optical measuring system uses 2048 signal periods for high-resolution evaluation in the drive controller. The feedback system is a multi-turn absolute device, so the axis can report position across multiple revolutions immediately after power-up. The 0450 winding code sets the electrical resistance and inductance values expected by compatible IndraDrive amplifiers, and the motor is supplied without a holding brake.
The housing is rated IP65, which helps block dust and water jets commonly encountered on factory floors. Continuous duty is supported in ambient temperatures from 0 to 40 °C when airflow around the housing remains unobstructed. The stator insulation meets class 155, which matches the thermal class used for the winding system. This combination supports use in enclosed machine sections that need a sealed motor body and stable heat handling during continuous operation.
Frequently Asked Questions about MSK075E-0450-NN-M2-UG0-RNNN:
Q: How is the MSK075E-0450-NN-M2-UG0-RNNN motor cooled?
A: The MSK075E-0450-NN-M2-UG0-RNNN motor uses natural convection for cooling without the need for external air supply.
