1MS160F-4U-A1

1MS160F-4U-A1, Bosch Rexroth Indramat, 1MB High-Speed Asynchronous Motors The 1MS160F-4U-A1 stator model from Bosch Rexroth Indramat’s 1MB High-Speed Asynchronous Motors series delivers a purpose-built frameless spindle interface for high-performance CNC and automated processing machines. Engineered for a frame size of 160 and a motor length of F, this stator accommodates multiple winding configurations—4A, 4B, and 4D—to match diverse torque and speed profiles. Its design emphasizes compactness and modular integration, fitting seamlessly into modern spindle housings without sacrificing rigidity or thermal stability. Rugged construction and precise manufacturing tolerances ensure consistent electromagnetic performance under demanding rotational loads.

Featuring a liquid cooling mechanism with an aluminum stator cooling jacket, the 1MS160F-4U-A1 achieves exceptional thermal equilibrium even at peak speeds. An air gap between rotor and stator further enhances convective heat dissipation, maintaining optimal winding temperatures. The stator ships with a 1.5 m cable loom length that includes three power wires enclosed in a high-temperature protective hose for enhanced dielectric strength. Rated for an Ingress Protection of IP00, this unit can be fitted with optional seals for harsher environments, and is backed by a global one-year warranty from Wake Industrial.

Integration into the Rexroth IndraDrive ecosystem is straightforward: the stator mates directly with frameless spindle rotors and couples with Rexroth frequency converters and servo modules for precise speed and torque regulation. Its liquid-cooled design and robust housing deliver high power density with minimal thermal drift, boosting machine uptime and reducing maintenance intervals. Ideal for direct-drive spindles in advanced CNC machines, processing lines, and transfer systems, the 1MS160F-4U-A1 balances dynamic response and reliability for the most exacting industrial applications.
