Product Description

Bosch Rexroth is a leading manufacturer of drive and motion control products used for diverse operations in the global drive market. It is the designer and manufacturer of the 1MB maintenance-free frameless spindle motors. These motors display a high power density and top-notch running smoothness. They are used as direct drives in main spindles and perform milling, grinding, and turning operations. The 1MR family of rotors is part of these motors, and they are components of the Rexroth IndraDrive drive system.

The 1MR375D-S125 is a model of the rotors in the 1MR series by Bosch Rexroth. The rotor is designed for the 1MB frameless spindle motor whose frame size is 375 and frame length is D. By detecting its position, the motor feedback system of its motor can relay the information to its control device, which regulates the speed and position of the spindle. To aid the cooling of the motor, a coolant fluid absorbs a significant portion of its power loss. Some of the heat generated by it is also transferred through cooling rings directly to the endplate. The rotor weighs 132kg and has a moment of inertia of 1.73 kgm2.

To align the 1MR375D-S125 to the spindle when it is mounted, it is frictionally engaged by a multiple die press group with the motor spindle. There are two fitting surfaces with graduated diameters on this spindle arranged close to each other. The fitting diameters ensure that the rotor can be unmounted safely. There are also balancing rings with tapped holes in front of it used to balance it to the desired vibration severity grade according to the DIN VDE 0530 standard. This unit can be shipped globally with a one-year warranty period from Wake Industrial.
