1MS240F-4A-A1

The Bosch Rexroth Indramat 1MS240F-4A-A1 stator is part of the renowned 1MB High-Speed Asynchronous Motors series, designed to deliver reliable performance in demanding industrial environments. With a Motor Size of 240, a frame length of F, and a Windings Code of 4A, this stator serves as the core electromagnetic component for high-speed asynchronous motors. Engineered as a liquid-cooled stator, it features an integrated aluminum cooling jacket that efficiently removes heat generated within the stator windings and a significant portion of the rotor, ensuring continuous operation under heavy load.

This stator is equipped with a sturdy aluminum cooling jacket through which coolant is circulated at a flow rate of 4.2 liters per minute. The rated power loss is 2.9 kilowatts, indicating its capacity to handle high thermal loads. Coolant inlet temperatures may range from 10 to 40 °C, optimizing heat exchange without risk of thermal shock. Electrical connection is facilitated by a 1.5-meter cable terminated with an enlarged output diameter for secure attachment. The protection category is IP00, reflecting its open design suited for integration within enclosed motor housings.

Weighing approximately 48 kilograms, the stator is designed for an ambient operating temperature of 0 to 40 °C and may be stored at temperatures from –20 to 80 °C. The insulation system is rated to class F, providing high thermal endurance. Bosch Rexroth Indramat recommends vertical storage and transportation to preserve the integrity of the cooling jacket interface, with lifting via parallel chains or ropes. The unit can be supplied standalone or preassembled within a complete 1MB motor; standalone installation must be performed by trained personnel following detailed product documentation. Backed by a one-year warranty, the 1MS240F-4A-A1 offers efficient thermal management, robust insulation, and seamless integration for critical industrial motor applications.
