1.2.3 Shaft Characteristics

There is a limit to the load that can be applied on the motor shaft. Make sure that the load applied on the radial direction,
when mounted on the machine, is below the tolerable values given below. These loads may affect the motor output
torque, so consider them when designing the machine.

CAUTION
Consider on the machine side so that the thrust loads are not applied to the spindle motor.

1.2.4 Machine Accuracy

Machine accuracy of the spindle motor's output shaft and around the installation part is as below.
(Excluding special products)
Accuracy
Run-out of the flange surface to the output shaft
Run-out of the flange surface's fitting outer diameter
Run-out of the output shaft end
(Note) Refer to Specifications Manual for the frame number of each spindle motor.
