1MR160H-B074/S001

The Bosch Rexroth Indramat 1MR160H-B074/S001 is part of the 1MB High-Speed Asynchronous Motors series, featuring a Motor Size: 160 and a Motor Length: H. With an Inside Diameter of Rotor: 74 mm, this frameless kit spindle motor is engineered for use as a direct drive main spindle motor. Designed according to UL standards and CE-certified, it provides reliable motion control in precision machining applications and maintains stability under high rotational loads.

In terms of detailed technical specifications, the 1MR160H-B074/S001 generates a continuous torque of 64 Nm at a constant current of 58 A and operates at a rated speed of 3000 rpm. It achieves a peak speed of 12000 rpm by drawing a peak current of 132.2 A. The rotor carries an IP00 protection classification and is designed with a <16-frame length "H"> and <4A winding code>. It requires installation in a stator specified by Bosch Rexroth and must be stored horizontally in a dry, dust-free environment to preserve its performance.

Additional features include an insulation class-F rating, a net weight of 9.8 kg, and compatibility with a 281 V main power source through the attached stator. The rotor operates within a permissible temperature range of 0 to +40 °C and can be installed at altitudes up to 1000 m above sea level. With a one-year warranty and strict adherence to storage and installation guidelines—such as protection against liquids and dust—the 1MR160H-B074/S001 offers exceptional durability, efficiency, and precise control for demanding industrial spindle applications.
