The spindle motor is a high speed AC motor with speeds ranging from thousands to tens of thousands, often used in conjunction with a frequency converter to control the motor speed. It is widely used for carving, polishing, and milling. It involves processing industries such as wood, aluminum, stone, hardware, glass, PVC,etc.It is characterized by fast speed, small volume, lightweight, low material consumption, low noise, and low vibration. There are two type of spindle motors including water cooled spindle motor and air cooled spindle motor. In the following paragraph, i will introduct for you seperately.
Water cooled spindle motor:
Under the same conditions, motors that have been water-cooled for a long time have a longer lifespan, more stability, higher accuracy, and lower noise compared to air-cooled motors. Because the heat inside the motor is quickly carried away by water, the heat exchange efficiency is high. But water cooling requires a water source, water pump, inlet pipe, and drainage pipe, which is not as convenient to use as air cooling. If it is used in a factory, it is better to choose water cooling.
Air cooled spindle motor:
Using a fan to cool the motor results in higher noise and lower accuracy compared to water cooling, making it easy to install, maintain, and use. The price of a single motor is slightly higher than that of a water-cooled one, but with the addition of water pumps and pipes, it is cheaper than water-cooled ones.
A CNC spindle motor is a type of motor used in computer numerical control (CNC) machines to drive the spindle, which holds the cutting tool or workpiece. The spindle motor provides the rotational power required for various machining operations such as cutting, drilling, milling, and routing. It is widely used in many field such as:
- CNC stepper motor: CNC lathe is the most commonly used in equipment field for spindle motors. Due to its large processing capacity and long working time, it is more important to pay attention to the wear resistance of the spindle when selecting it. When selecting the spindle motor, it is necessary to achieve precise control through a servo device, and the spindle motor specifications can also be customized according to the size and usage needs of the CNC lathe.
- Various types of carving machines: It is used for carving various molds, metal accessories, or stone materials. The spindle motor used on the carving machine is generally a high speed motor with a high rated power to meet the requirements of rapid carving use.
- Machining centers: Each machining center cannot be separated from the power supply of the spindle motor, and when selecting, it should be able to adapt to low-speed strong cutting and meet the requirements of high-speed precision machining. In addition, the spindle motor should be suitable for the use of quasi stop or emergency stop functions.
- Grinding machine equipment: The grinding machine is mainly used for grinding and milling various hardware workpieces, which require multiple steps such as wire cutting or electric discharge machining. Therefore, when selecting the spindle motor, it is important to pay attention to selecting the size that is suitable for the production needs of the grinding machine.
