The R911274570 (1MS242N-4B-A1/S045) stator is designed for integration in Bosch Rexroth 1MB asynchronous frameless spindle motors. It features a class-F insulation category and operates within a temperature range of 0 to 40 °C, with storage limits between -20 and +80 °C. The stator, with two pole pairs and a winding resistance of 0.084 Ohms, includes a built-in overtemperature sensor and utilizes an aluminum cooling jacket capable of dissipating 3 kW at 3 bars pressure. Rated for a maximum installation altitude of 1000 meters, it provides 185 Nm torque, 33 kW power, and supports a continuous current of 98 A to reach up to 6800 rpm. The unit, weighing 81 kg, is intended for use with a matching rotor and operates at a nominal voltage of 282 V. IP00 protection restricts use to dry environments only. Professional installation and maintenance are required.
