The spindle motor is also called a high-speed motor, which refers to an AC motor with a rotational speed of more than 10,000 rpm/min. Mainly used in wood, aluminum, stone, hardware, glass, PVC, and other industries. 1- Built-in: this type power transmission is by integrated motor inside the spindle there are some other names as motorized spindle, electro-spindle and integrated spindle. Advantages: Low weight. Reaching the high speed like 35.000- 50.000 rpms.
Electrical motors are most commonly used as spindle drives. Depending on the requirements on the machine tool, 3 different types of rotational electrical motors can be employed here: The DC motor, the synchronous motor and the asynchronous motor. The machine tool spindle provides the relative motion between the cutting tool and the workpiece which is necessary to perform a material removal operation. The two types of spindle fibers are the kinetochore and interpolar fibers.
The main uses of spindle motors are power sources such as drilling, cutting and grinding tools, and tools such as drills are attached to the tip. It can also be used for machining robots, and is used for machining high-precision parts by taking advantage of its high controllability. A spindle is a rod in a machine, around which another part of the machine turns. A spindle is a pointed rod which you use when you are spinning wool by hand. You twist the wool with the spindle to make it into a thread.
