ER11 Spindle Motor Kit [12000rpm] [48V]

This is an ER11 Chuck CNC 300W Spindle Motor with 52mm Clamps and AC 110-220V Power Supply Speed Governor For CNC Machine.

A machine tool may have several spindles, such as the headstock and tailstock spindles on a bench lathe. The main spindle is usually the biggest one. References to "the spindle" without further qualification imply the main spindle. Some machine tools that specialize in high-volume mass production have a group of 4, 6, or even more main spindles. These are called multispindle machines. For example, gang drills and many screw machines are multispindle machines. Although a bench lathe has more than one spindle (counting the tailstock), it is not called a multispindle machine; it has one main spindle.

Spindle motors are high-precision, high-reliability electric motors. Spindles can be used for industrial 3 and 5 axis CNC routers. They are also used on CNC milling machines and robots. In addition, motor spindles have various cooling methods including air-cooled and liquid-cooled. Electrospindles are used in the manufacturing of plastics, wood, metal, and composites.

It also includes a 52mm motor special fixed seat (free set screws) + new 300W spindle + new 48V 360W adjustable switching power supply (digital display can be selected, shows the real-time operating voltage).

The spindle comes with forced air cooling, so it can work for a long time.
