Product Description

The 1MS160N-4B-A1/S045 is a stator for the asynchronous spindle motor from Bosch Rexroth. It is specifically designed for use with motor-driven spindles. For this application, this unit facilitates the conversion of the rotating magnetic field generated by the spindle to electric current. The 1MS160N-4B-A1/S045 is often deployed with the 1MB kit spindle motor, which is typically used for grinding, milling and turning in special machinery, transfer lines, and machining centres. Its operating speed is rated 2000 RPM; maximum speed is 8000 RPM, and its rated power is 18.6 kW. The 1MS160N-4B-A1/S045 operates at a current rating of 60 Amperes, and its maximum attainable current is 135.5 Amperes.

The 1MS160N-4B-A1/S045 is a 1MS stator, and its protection rating is IP 00, leaving it unfit for exposure to solids or liquids. The rated torque of this model is 89 Nm, and its maximum attainable torque has a value of 223 Nm. Its direct current Bus Voltage rating is 540 V. Furthermore, the supply temperature of the 1MS160N-4B-A1/S045 is 30 degrees C. This model’s motor-winding temperature is 130 degrees C. During use, the permissible ambient temperature of this 1MS160 stator is between 0 – 40 degrees C.

The 1MS160N-4B-A1/S045 stator weighs 28.1 kg and comes with two pole pairs, making it suitable for use with a 4-pole motor. Its thermal time constant has a value of 5 minutes, and its windings have an inductance of 2.02 mH. The frame size of this stator is 160, and its length is designated “N.” It features an aluminum cooling jacket used side by side with a standard liquid (water) cooling mechanism. The power cable cross-section of the 1MS160N-4B-A1/S045 is 16 mm². This unit can be shipped globally with a one-year warranty period from Wake Industrial.
