Product Description

The 1MR rotors are rotors of the Bosch Rexroth 1MB frameless spindle motors. These liquid-cooled asynchronous motors are used as direct drives in motor spindles. They have a high rigidity, high power density and unique running smoothness. Their parts include rotors and stators, and they are components of the Rexroth IndraDrive drive system. Their common operations include milling, grinding, and turning in equipment like in machine tools, transfer lines, processing centers and special-purpose machines.

The 1MR310D-A108/S027 is a Bosch Rexroth rotor model in the 1MR series. It is a component of the 1MB frameless spindle motor with a frame size of 310 and frame length indicated as D. Its design is one with a step interference fit, and there are balancing rings in front of it. These balancing rings have tapped holes in front of them and are used to balance the motor to the desired vibration severity grade based on the DIN VDE 0530 requirement. It is frictionally engaged with the motor spindle by a multiple die press group, and this aids the alignment of both parts when the rotor is mounted.

The laminated core of the 1MR310D-A108/S027 has a protective lacquer coating to prevent its corrosion during transport and storage. The inside diameter of the rotor is 108mm, and its moment of inertia is 0.492 kgm². Its Ingress Protection Rating Is IP 00; hence it is not protected against water jets or damage due to the entry of solid objects. To ensure its prolonged optimal use, the use of protective seals should be adopted, especially in damp or foggy atmospheres. It can be cooled through cooling rings connected to the endplate. This unit can be shipped globally with a one-year warranty period from Wake Industrial.
