1MS160N-4B-A1/S046

1MS160N-4B-A1/S046, manufactured by Bosch Rexroth Indramat in the 1MB High-Speed Asynchronous Motors series, delivers advanced motion control in a robust industrial package. This high-performance stator features a Motor Size of 160 and a Motor Length of N, accommodating windings coded 4A, 4B, 4C. Designed for direct three-phase mains operation, it integrates seamlessly with standard drive systems. Engineered for demanding applications, it balances power density with exceptional thermal management.

Incorporating an IP00 protection class and an aluminum cooling jacket, the 1MS160N-4B-A1/S046 sustains continuous output of 18.6 kW at 2000 rpm under ambient temperatures from 0 to +40 °C. It draws a rated current of 60 A to generate continuous torque of 89 Nm, while dissipating 4 kW of heat and maintaining stator insulation at class F. The motor’s thermal time constant of 5 min and its 2 pole pairs ensure rapid temperature stabilization and precise speed control. At only 28.1 kg, the stator includes a 1.5 m cable for immediate connection and supports up to 1000 m elevation without derating.

Engineers will appreciate the 1MS160N-4B-A1/S046’s straightforward integration into CNC spindles, gearbox drives, and high-speed spindles. Its proven reliability and adherence to the 1MB user manual installation guidelines minimize downtime and extend service intervals. Backed by a one-year warranty, this motor is ideal for grinding, milling, printing, and turning machines where consistent high-speed performance is critical.
