1MS160N-4A-A1

1MS160N-4A-A1, Bosch Rexroth Indramat, 1MB High-Speed Asynchronous Motors opens as a high-performance stator element engineered for frameless main spindle applications. This stator features a Motor Size of 160 with a precision-matched Motor Length designated as N. Its winding identification comprises codes 4A, 4B, and 4C to support versatile configuration and power delivery. The unit serves as the stationary core of a complete asynchronous motor when combined with the appropriate rotor assembly.

Designed to deliver robust and continuous operation, the stator provides Rated Power of 10.5 kW at a nominal speed of 3000 rpm. The Insulation Class is specified as F, enabling safe operation in moderately damp environments. Its Windings Code cluster of three distinct configurations optimizes thermal distribution, while the Resistance of 0.147 Ω ensures minimal copper losses. Weighing 28.1 kg and producing a rated torque of 89 Nm in the matched rotor, the assembly maintains a Power Loss rating of 4.8 kW under full-load conditions. Operational across an Operating Temperature range from 0 … +40 °C, it is suited for standard industrial climates.

Integration into existing automation systems benefits from the frameless construction, allowing the stator to be flangelessly mounted to custom housings and coupled directly to precision bearings. The absence of an external housing reduces inertia and enhances dynamic response, while compatibility with high-resolution encoders delivers accurate feedback for closed-loop control. Built to Bosch Rexroth Indramat’s stringent quality standards, the stator ensures reliable performance, simplified maintenance, and long service intervals in high-speed spindle, milling, and drilling applications.
