RATTMMOTOR 2.2KW Spindle Motor 110V Square Air Cooled Spindle Motor ER20, 24000RPM High Speed Spindle Motor 4 Bearings 3-Phase 5A 400Hz for CNC Router Engraver Milling Cutting Machine 24000RPM/ER20 Collet and Nut/Four Bearings
Unlike other square spindle motors of the same model that can only reach 18,000 rpm, the maximum speed of this spindle motor can reach 24,000 rpm. Equipped with 4 high-quality 7 series P4 grade bearings and precision-made ER20 collets and nuts, and incorporating dynamic balancing technology, the power is strong, which can not only reduce the noise and wear during the spindle operation, but also reduce the knife breakage.

ER20 Collet and Nut
Precision crafted ER20 collet and nut, high precision and reduced the rate of knife breakage.
Four Bearings
Using optimized 7 series P4 grade 7002 and 7005 bearings, this series of bearings has strong hardness and rust resistance, as well as dynamic balancing technology, the actual runout off of the spindle is close to 0.01 mm, the precision tapered bore is less than 0.005mm, high precision and durable.
Air Cooling Methods
Using a scientific fan design that can use air circulation to cool the heat generated by the spindle at high speed, the heat dissipation effect is better, and the smooth and stable operation of the spindle can be well improved. At the same time, there is no need for water pumps and water pipes, and the spindle is air-cooled and dissipated, making it more convenient to use.
Aluminum Casing
The body shell of the spindle is made of aluminum alloy. Compared with stainless steel, the aluminum material has better heat dissipation performance, and the surface is smooth and does not rust.
Pure Copper Coil
The conductivity of the pure copper coil is very good, which can effectively exert electric energy, reduce consumption, and dissipate heat very well.
No Punching Required
There are installation holes on both sides of the machine, no need to punch holes, users can install the machine according to their own needs according to different hole distances, which is more convenient to use
Wire Box
The upgraded version of the top junction box makes the spindle wiring simpler and safer. The wiring method of the spindle motor and the inverter is as follows:
- VFD's U= Spindle's U1
- VFD's V= Spindle's V1
- VFD's W= Spindle's W1
- Connect any 2pin terminal "R", "S" or "T" of the inverter to "220VAC".
Dust Proof Design & Low Noise
- The stainless steel seal design at the front end of the spindle can prevent dust or impurities from entering the interior of the spindle, which can better extend the service life of the bearing.
- Humanized noise reduction design, low noise when the spindle is running, can create a more comfortable working environment.
Applicable Engraving Materials
- The Spindle motor is mainly suitable for NON-metallic engraving.For example: wood, plastic, acrylic, pvc, pcb, carbon fiber, density board and soft metal like copper, aluminum and the similar materials.
