¥Note¥ *1) After shrink-fitting the rotor to the spindle, apply finish machining to outer surface of the rotor and each part bearings to be placed at the same process. Final finishing diameter is 114.2 +0.01/-0.01. *2)Before shrink-fitting, apply finish machining to rotor bore within the dimension of Ef +0.01/-0.01. "Ef" could be from 74.4 to 77 , so please choose the value. When machining, please refer to the reference figure below. *3) To assemble the shaft and rotor, apply shrink-fitting at maximum 200 degrees centigrade. Ideally, within 180 degrees centigrade.
