1MS160F-4E-A1/S045

The Bosch Rexroth Indramat 1MS160F-4E-A1/S045 from the 1MB High-Speed Asynchronous Motors series is engineered for high-performance industrial applications. With a motor size 160 frame and a motor length F, it delivers compact power density while conforming to the Windings Code 4A, 4B, 4D specification for versatile winding arrangements. Housed in an open construction with IP00 protection class, this stator core integrates an aluminum cooling jacket that supports liquid-assisted thermal management. Each unit is factory-labeled for easy identification and traceability, ensuring compliance with stringent American and European quality standards.

At a reference temperature of 20 °C, the 1MS160F-4E-A1/S045 exhibits a torque constant of 2.25 Nm/A and a winding resistance of 0.939 Ω, enabling precise torque control in high-speed rotor assemblies. The stator requires a rated input current of 23.2 A to generate a rated output power of 12.5 kW and achieve a nominal rotational speed of 2 500 rpm. Its compact footprint, measuring 240 mm in length with a diameter of 177 mm, combines with a total mass of 15.8 kg to facilitate integration into high-speed drive modules. The robust construction is designed to withstand continuous duty cycles and maintain electrical integrity under demanding load profiles.

Liquid cooling is supplied via an integrated coolant duct with a volume of 0.90 L, supporting a maximum permissible inlet pressure of 6.0 bar to optimize heat removal during peak operation. The stator is rated for operation in ambient temperatures from 0 to 45 °C and at altitudes up to 1 000 m above sea level, ensuring reliable performance in diverse industrial environments. Each unit is backed by a one-year warranty, providing peace of mind for system integrators and end users worldwide.
