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

Description:
In machine tools, a spindle is a rotating axis of the machine, which often has a shaft at its heart. The shaft itself is called a spindle, but also, in shop-floor practice, the word often is used metonymically to refer to the entire rotary unit, including not only the shaft itself but its bearings and anything attached to it.
A spindle motor is a small, high-precision, high-reliability electric motor that is used to rotate the shaft, or spindle, on which the platters are mounted in a hard disk drive.
In some cases, the spindle motor can be made to accurately position by means of feedback to the controller for functions such as orientation for tool changing and can even be done with induction motor technology, usually 3 phase-type.
The CNC spindle is the heart of any mill. It consists of a rotating assembly with a taper where tool holders may be installed. A CNC spindle motor with the optional transmission of some kind rotates the CNC spindle. The transmission matches the highest power rpm range of the CNC spindle motor to the spindle RPMs that are ideal for the particular speeds and feeds of the material being cut.
CNC spindle motor contains different types of spindle. This kit comes standard with a 3.175mm chuck. This motor is widely used by DIY users, with a good response, high speed and low noise, suitable for engraving PCB, acrylic, drilling, etc.
