1MR310F-A112

1MR310F-A112, Bosch Rexroth Indramat, 1MB High-Speed Asynchronous Motors. The 1MR310F-A112 rotor is engineered to deliver precision and power within encapsulated spindle systems. It features a Motor Length of F, a Motor Size of 310, and a Rotor Design of With Step Interference Fit, enabling robust fit and minimal radial play. Paired with a matching stator, this unit transforms into a frameless asynchronous motor optimized for high-speed performance.

Designed for demanding industrial applications, the 1MR310F-A112 achieves a Rated Torque of 480 Nm at Rated Speed of 1600 RPM. Its stator winding exhibits a Winding Resistivity of 0.38 Ω at 6 A, while the rotor sustains a Rated Power of 20–35 kW. With an Insulation Class F system and an Internal Diameter of 112 mm, the assembly resists thermal stress and maintains dielectric integrity. A measured Power Loss of 5.5 kW underscores the design’s efficiency, and the rotor performs reliably across an Operating Temperature range of 0 … 40 °C, with safe shipping from –20 … +80 °C.

Integration into machine spindles benefits from the step-interference fit, which ensures vibration-free operation and consistent torque delivery. The frameless design allows direct coupling to custom housings, reducing footprint and enhancing system modularity. Bosch Rexroth Indramat’s stringent quality control and the 1MB series’ proven track record guarantee long-term reliability and seamless incorporation into high-speed automation environments.
