VEVOR ER20 CNC Square Air Cooled Spindle Motor

Instructions for use

1) In use, must first connect the cooling water pipe, make spindle connect cooling water and then start.

2) Before driving, turned by hand spindle. If sensory block is not flexible, you should troubleshoot, and then check the direction of rotation of the spindle from the spindle end to see if the match should rotate counterclockwise power wiring should be changed to make it consistent.

3) Before driving, cooling water for grinding workpiece can’t be in the front end of the spindle cover, to prevent the front bearing cover slot inlet burning motor and bearing. the motor must not enter the water, after turned on of the motor, when you live in grinding the workpiece to open the grinding of workpieces coolant. First off the workpiece coolant shutdown, and then close the spindle motor.

Maintenance and Service

1) Motorized spindle by medium frequency power supply rated voltage, frequency should be consistent with electric spindle technology parameters, motorized spindle rotational speed can change the frequency to adjust, also directly proportional voltage change.

2) When the spindle is temporarily not in use, should use compressed air to blow the coolant water,to avoid rusting, plug the hole. Spindle surface should be coated with anti rust oil. The shaft end protecting device, placed in dry place.

3) If replacement the spindle of bearings, best professional and technical personnel from the replacement. Use special tools, stator coil does not to be removed.

Dynamic Balance Technology

Unlike other milling spindle motors, we use innovative and advanced dynamic balancing technology. The ER20 standard collet’s advantages are excellent rigidity, full strength, unique drainage design, and high precision.

Four High-quality Bearings

The upgraded bearing has two significant advantages: superior durability and anti-rust performance. High speed (24000R/min) and strong power bring higher efficiency than before.

Noise Reduction and Air Cooling

Our CNC router spindle motor works with low noise and avoids auditory fatigue. It uses air circulation to cool the heat generated by the spindle at high speed and has a good heat dissipation effect.

Premium Material

The aluminum body ensures greater power and longer life; Unlike ordinary aluminum-clad wire, the oxygen-free copper coils can ensure high-quality processing and engraving performance.

Refined Internal Details

The CNC router spindle is a built-in wire box directly connected to the wire or VFD, effectively improving the stable and smooth operation. The upgraded wrench is provided for easy handling.

Wide Application

Air-cooled motors commonly applied materials such as wood, stone, mold & metal, etc. Suitable for machinery manufacturing, sheet metal processing, guardrails, factories, shipyards, home improvement, construction, and other fields.

• Technical Parameters: Spec: φ2.4 x 10.3 in (Diameter: 6.2 cm x Length: 26.1 cm); Power: 2.2KW; Voltage: 220V; Current: 7.8A; Collet Size: ER20; Bearings: 4 bearings; Frequency: 400 Hz; Speed: 24000 R/min; Runout off: less than 0.002 mm. Mainly used for engraving machine or used with frequency converter.
• ER20 Standard Collet: The collet of the CNC router spindle is quenched with manganese steel, and the runout is less than 0.002 mm, which has high precision and is not easy to break the knife, increasing the stability of the working process. Dynamic balance technology can effectively reduce noise during use.
• Powerful Bearing: The air spindle motor adopts imported bearings with high accuracy, precision, and durability. Significantly improve the hardness and anti-rust performance.
• Low Noise & Heat Dissipation: The dynamic balance technology can effectively reduce the noise during use. The scientifically designed air cooling system has a better heat dissipation effect to ensure smooth operation.
• Wide Application: The CNC spindle motor kit is mainly used for engraving machines or frequency converters. It uses air circulation to cool the heat and has a good heat dissipation effect.
