7-3 Selection of the power supply unit

(b) Spindle rated output

The spindle rated output is calculated from the following expression.

Spindle rated output

=Spindle motor rated output x motor output coefficient

β of the combined spindle drive unit

For the spindle motor rated output of the above expression, use the value calculated in (a).

For the motor output coefficient of the combined spindle drive unit, use the value corresponding to the

used spindle drive unit in the table 2.

1. When the spindle motor applies to the wide range constant output specification or the high-torque

specification, the spindle rated output may become large.

2. The spindle rated output is calculated from the motor output coefficient of the spindle drive unit

used in combination with the spindle motor.
