Product Description:
Bosch Rexroth Indramat supplies the MRS142F-1N-0058-M243 rotor as a component in the MRS Synchronous IndraDyn H Motors series. The unit is classified as a rotor for synchronous spindle drives and serves as the rotating mass that transfers magnetic torque from the stator to the machine shaft. Within industrial automation cells, this element supports rapid tool changes, high-quality surface finishing, and precise positioning when integrated with the corresponding motor housing and feedback devices.
The rotor has a frame size of 142 and a frame length code of F, providing a fixed outer diameter and stack depth for installation in the motor housing. A smooth internal bore measuring 58 mm centers the rotating assembly on the spindle shaft, while the rotor has a total length of 261 mm to accommodate the magnetic stack used for torque production. The rotor uses smooth rotor drilling to support balanced mass distribution during rotation. Its mounting interface has plain drilling, allowing direct attachment without keyed features. These dimensions support proper alignment within a compatible IndraDyn H motor frame and help maintain low runout during high-speed operation.
The rotor is suitable for operation at ambient temperatures from 0 to 40 °C. This operating range is appropriate for typical enclosed machine installations and helps limit thermal expansion that could affect concentricity. The surrounding motor uses class F winding insulation to withstand elevated internal temperatures during operation. The open construction has an IP00 protection rating, so protection against contact, foreign objects, and moisture must be provided by the surrounding motor casing. Correct shaft alignment and bearing support are necessary to preserve the rotor’s balance and maintain clearance between the rotating and stationary motor components.
