What is a Spong ball?

A spindle motor is a motor in which the motor part of the power source and the rotating part are integrated. Since there is only one rotary axis, the device configuration is simple. A spindle is the axis of rotation of a rotating machine. It is also called a spindle unit, and is a term used for machine tools such as lathes. Therefore, a spindle motor refers to a motor integrated with a spindle. A typical rotation control device consisting of a motor, gear, and belt tends to be complicated to control due to the large number of parts. Furthermore, equipment tends to be large, but using a spindle motor saves space and makes it easy to add multiple rotating axes in parallel.
