1MR160D-A061

The Bosch Rexroth Indramat 1MR160D-A061 from the 1MB High-Speed Asynchronous Motors series is a high-performance frameless rotor designed for precision spindle applications. This motor size 160 unit features a motor length D profile and supports dual windings codes 4A, 4B for flexible speed control. Engineered for liquid-cooled operation, the rotor delivers seamless integration with the matching stator assembly and meets industrial demands for high-speed rotation. Its robust design ensures stable performance in demanding manufacturing environments.

Under the 4A stator winding, the 1MR160D-A061 achieves a rated speed of 3000 rpm while drawing a rated current of 48 A, and under the 4B winding it maintains a constant 2000 rpm with the same current draw. The rotor produces a rated torque of 32 Nm at a rated voltage of 171 – 370 V and generates power in the range of 6.7 – 10 kW. Stator inductivity spans 1.57 – 7.23 mH, contributing to smooth torque delivery. With an IP00 protection class and a liquid-cooling design, the rotor tolerates humid conditions without condensation and is shipped for operation in temperatures from –20 °C to +80 °C.

The rotor’s inside diameter of 60.3 mm ensures precise fit in the spindle, and its finished step interference fit design simplifies assembly. Each unit arrives packed in Styrofoam half-shells and must be stored or transported horizontally to preserve balance integrity. Optimized for ambient operation between 0 °C and +40 °C, the 1MR160D-A061 includes a one-year manufacturer warranty for added assurance of quality and reliability.
