Product Description:
The MRS142B-1N-0058-NNNN is an open-frame synchronous motor supplied as a kit for integration into machinery. It belongs to the MRS Synchronous IndraDyn H Motors series and is engineered by Bosch Rexroth Indramat. As a kit motor, the component mounts directly onto a customer's mechanical structure to generate rotary motion without a conventional housing, allowing compact positioning stages, indexing tables, or distributed drive axes to be built with minimal radial play. This arrangement lets the motor become part of the machine structure, which can reduce overall envelope size and remove the need for a separate external frame.
The motor uses an open kit motor design, meaning the stator and rotor are delivered without an enclosure so heat can be removed by the host machine. In place of a sealed body, the installation relies on external guards, which is why the factory degree of protection is IP00. The permitted ambient temperature range is 0 °C to 40 °C, and the installation altitude is limited to 1000 m. Operation outside those limits can shorten insulation life or affect magnetic alignment. Because the active parts remain exposed until installation is complete, the surrounding machine structure must provide the necessary guarding and a stable thermal path.
When energized, permanent-magnet attraction creates an axial pull of 265 N and a radial pull of 635 N, so machine bearings and thrust washers must be sized for those continuous forces. Those magnetic forces are present during operation and must be considered when supporting rotor and stator alignment. Acoustic emission reaches up to 75 dB(A), so sound attenuation may be needed in occupied areas. Because the motor is supplied without a fan or housing, any added guarding must leave the laminations accessible for cooling and must not interfere with the stated force or noise values.
