1MS240B-4A-A1

The Bosch Rexroth Indramat 1MS240B-4A-A1 from the 1MB High-Speed Asynchronous Motors series is a frameless stator designed for high-speed spindle applications, featuring a Motor Size 240, Motor Length B and Windings Code 4A. Its liquid cooling mechanism incorporates an aluminum stator cooling jacket through which coolant flows to maintain thermal equilibrium, while the integrated air gap enhances heat dissipation from the rotor. Electrical connections are provided via a 1.5 m loom with three power wires, housed in a protective hose with high-temperature insulation and terminating at a larger-diameter stator end. With a protection class of IP 00, this stator requires appropriate sealing in damp environments and is engineered for precise, reliable performance in demanding industrial systems.
