Product Description

Bosch Rexroth is a global manufacturer and supplier of different classes of innovative engineering products with applications in the drive and motion control industry. The frameless spindle motors of the 1MB series are designed by the company. They have several applications, as seen in processing centers, machine tools, transfer lines, and some special-purpose machines. They are liquid-cooled asynchronous motors used as direct drives in motor spindles. The rotors for this class of frameless spindle motors make up the 1MR series.

The 1MR310D-A118/S026 is a rotor model in the Bosch Rexroth 1MR series of rotors designed for the 1MB frameless spindle motors. It is made up of a sleeve with a laminated core and balancing rings for achieving equilibrium. The motor for this rotor model has a frame size of 310 and a frame length D. With a design that features a step interference fit; the rotor is easy to mount and dismount. This design also ensures the smooth running of the spindle and increases its rigidity.

The inner diameter of the 1MR310D-A118/S026 is 118mm. It weighs 80kg and its moment of inertia is 0.492 kgm². Thanks to an air gap, heat generated by it is transferred to the stator of the motor, where it is dissipated by a liquid cooling system. It belongs to the IP 00 protection class according to IEC 60529 and can be affected by long-term use in damp environments or humid atmospheres. Hence, it requires the use of suitable protective covers for its optimal operation in such environments. The proper ambient temperature at the site of operation of the device falls between 0^o C and 40^o C. This unit can be shipped globally with a one-year warranty period from Wake Industrial.
