The 1MR313F-A112 is a rotor designed for Bosch Rexroth 1MB motors. Rexroth 1MB motors are asynchronous spindle motors. The frame size of the motor for which the rotor can be used is 313. The frame length of the motor for which the 1MR313F-A112 can be used is F. The rotor is designed with step interference fit and is readily usable. The inside diameter of the rotor is 112 millimeters. Motor feedback measures the rotor position sand reports it to the control device responsible for regulating the speed and position of the spindle. The major portion of the rotor power loss is absorbed by liquid coolant. This power loss is transferred to a superordinate coolant in the refrigeration unit. During transport, it should be ensured that the fitting on the inside of the 1MR313F-A112 rotor is not damaged.
If the inside lining gets damaged, then it may become impossible to remove the rotor from the spindle. The rotor should only be lifted and transported with sling hoisting belts made of plastic or which a special hook that is sheathed in plastic. A type plate on the 1MR313F-A112 lists important specifications. The plate is attached so that it is easily visible. Additionally, the following information is struck into the thick end of the stator inside the cooling jacket: type code, serial number and month and year of manufacture. The steps involved in rotor mounting include preparation for mounting, shrinkfitting of the rotor to the stator, rotor dressing to final dimensions, rotor balancing and rotor attachment to spindle for further mounting. Installation and mounting of the 1MR313F-A112 rotor should only be performed by trained and qualified technical personnel. This unit can be shipped globally with a one-year warranty period from Wake Industrial.
