1MR310D-A108/S027

The Bosch Rexroth Indramat 1MR310D-A108/S027 rotor from the 1MB High-Speed Asynchronous Motors series is engineered for demanding spindle applications with a motor size of 310 and a motor length of D. Featuring a precision step interference fit rotor design, this unit delivers exceptional concentricity and dynamic balance. Its hardened laminated core is protected by a lacquer coating that prevents corrosion during transport and storage. The rotor’s inside diameter of 108 mm and a moment of inertia of 0.492 kgm2 ensure optimized responsiveness and torque density.

Assembly and service are simplified by front-positioned balancing rings with threaded tapped holes, enabling trimming to the required vibration severity grade per DIN VDE 0530. Frictional engagement via a multiple die press group guarantees accurate alignment when mounting to the motor spindle. The unit carries an IP00 ingress protection rating, making it essential to employ protective seals in humid or dusty environments to preserve internal components.

Integration into liquid-cooled systems is supported by externally mounted cooling rings on the endplate, facilitating continuous heat dissipation in high-speed operation. Shipped with a global one-year warranty, the 1MR310D-A108/S027 rotor offers reliability and repeatable performance for milling, grinding, turning, and other precision machining processes.
