The R911246959 (1MR160E-A055) is a rotor component for IMB asynchronous spindle motors, designed by Rexroth Indramat. The rotor features a high metallic content and is engineered for demanding industrial environments, including those involving potential exposure to explosive atmospheres. It operates in conjunction with the stator's electromagnetic field, enabling precision rotation. An integrated encoder supplies positional, speed, and acceleration data to the system controller. The rotor relies on the spindle motor's liquid cooling and grease-lubricated ball bearings for thermal management. Power loss is influenced by the harmonics of input current and pulse width modulation frequency. The rotor is specified with an inside diameter of 55 mm, compatible with a motor size of 160 and a motor length classified as E. Maximum operational speeds can reach 20,000 RPM, with a moment of inertia specified for accurate integration into industrial systems.
