1MS480A-GA-A2

The 1MS480A-GA-A2, Bosch Rexroth Indramat, 1MB High-Speed Asynchronous Motors stator modules are engineered for ultra-high-speed operation, supporting frame size 480, frame length A, and winding code Unspecified. This stator integrates seamlessly into complete 1MB motor assemblies rated for up to 20,000 RPM and delivering continuous torque up to 875 Nm. Constructed with a precision-machined iron core and encapsulated within an aluminum cooling jacket, the module achieves optimal electromagnetic performance and thermal dissipation. A 1.5 meter power cable with a reduced diameter exit ensures reliable electrical connectivity and ease of installation.

Engineered for demanding industrial environments, the 1MS480A-GA-A2 features liquid cooling with an integrated jacket that channels coolant uniformly around the core, extracting waste heat from both stator and rotor sections. The recommended storage temperature range of –20 °C to 80 °C and strict vertical handling orientation protect the aluminum cooling jacket and maintain alignment tolerances. Mounting procedures include precision alignment of the O-ring seals, torque-controlled fastening of the stator housing, and secure termination of the internal windings via the factory-supplied cable assembly. As a maintenance-free electrical machine component, the stator is sealed against ingress, preserving its dielectric integrity and prolonging service life.

Designed for global shipping with a one-year warranty, the 1MS480A-GA-A2 stator delivers exceptional reliability and repeatable performance. Its compact, fully liquid-cooled architecture simplifies integration into high-speed synchronous drives, aerospace spindles, and precision machine tools. By minimizing thermal gradients and eliminating the need for external cooling hardware, this Bosch Rexroth Indramat module ensures uptime and consistency in critical rotational applications.
