The R911264394 (1MR375B-A170) is a rotor designed for the Bosch Rexroth 1MB series of frameless spindle motors, with compatibility for frame size 375 and motor length B. The rotor features a step face interference fit and a precisely processed outer diameter, contributing to accurate spindle speed and position control in direct-drive applications. It has a 170 mm inner diameter, weighs 106 kg, and has a moment of inertia of 1.39 kg·m². The stator is designed with an aluminum cooling jacket to facilitate efficient heat dissipation through the air gap. Rated IP00, this rotor is not protected against moisture and must be stored in a dry environment. Supplied with a corrosion-resistant lacquer for protection, the coating should be removed prior to installation and can be reapplied if needed. The recommended operating range is 0°C to 40°C, and installation should not exceed 1000 meters above sea level.
