Electrical and mechanical specifications include: power of 2.2 KW, current of 8 A and voltage of 220 V, speed of 10-24000 rpm, and weight of 1 kilo. The frequency is 400 hertz. Runout off: 0.01 mm, 0.01 mm, 0.01 m. ER20, ER21, ER22, ER2. Cooling options include water cooling and air cooling. Milling, for example, is an application. The primary applications are in the wood, glass, and PVC industries. The spindle motor is responsible for turning the spindle. Designed primarily for non-metallic engraving applications. Engraving machines are examples of their application.
Superior durability and anti-rust performance are two of the main advantages of upgraded bearings, which are also known as “powerful bearings. The efficiency of the high-speed core has been greatly improved over the past few years.
Anti-rust Material- The use of acid-resistant materials increases the durability and sturdiness of the CNC router spindle motor. The metal casing significantly increases cooling efficiency while also dissipating heat more quickly.
Advanced Balance Technology- Dynamic balance technology has the ability to significantly reduce noise during the course of operation. Increases in the efficiency and service life of the CNC router spindle can be achieved by using special tools. The nut is made of manganese steel and is hardened to a high degree of precision, making it difficult to break the knife.
A wide range of applications is served by the CNC Spindle Motor Kit, with the majority of applications being for engraving machines or in conjunction with a frequency converter. When the spindle is spinning at a high speed, it uses water circulation to cool the heat generated, and it has a good heat dissipation effect.

Application.
In addition to wood carving/engraving machines, advertisement engraving machines and CNC machines, small-scale processing centers and high-speed centrifuges can be found in the market.
Precautions.
1. Characteristics of the structur.
1) The high-speed electric main bearings are all C-class high-speed angular contact ball bearings, with axis sets of loading that improve spindle stiffness and precision grinding when operating at high speeds.
2) Before driving, turn the shaft by hand to ensure proper alignment.
The use of a cooling liquid circulating system to eliminate the high speed rotation of the spindle caused by temperature rise is recommended.
instructions for use (second paragraph.
In order to use the machine, you must first connect the cooling water pipe, then connect the spindle to the cooling water, and then turn it on.
It has extremely low runout, with a measurement of 0.005mm.
The only significant flaw (which is disclosed in the description) is that the claim is not supported by evidence. It is possible to get a good “tickle” from the spindle and the ground when it is running at low speeds because of the 105 volt differential between the spindle and the ground.
Adding a ground wire from the electrical connector to the housing is a simple solution to the problem.
