One, the basic situation of the spindle motor
The general sense of the spindle motor, also known as the high-speed motor, refers to the number of revolutions of more than 10,000 rpm AC motor. Mainly used in wood, aluminum, stone, hardware, glass, PVC and other industries, it has a fast speed, small size, lightweight, low material consumption, low noise, low vibration and other advantages, more and more by the relevant industries and applications.
In the modern society of high-speed progress of science and technology, due to the spindle motor is widely used, coupled with its meticulous workmanship, fast speed and higher processing quality of the motor, so that the spindle motor by the carving industry's favor, in the process of woodworking engraving play an increasingly important role in the processing.
And now appear on the market spindle is a machine tool spindle and spindle motor into one of the new technology, is the main functional components of CNC engraving machine tools. It adopts the mechatronics new technology, new technology, new materials, with frequency stepless speed regulation, low noise, smooth running, reliable and better load characteristics. It is used for high-speed drilling, milling and engraving machine tools.
Spindle motor specifications are 1.5KW/2.2Kw/3.0KW/4.5KW. Water-cooled 1.5KW spindle motor
Spindle motor material: 304 stainless steel jacket, water jacket for the high cast aluminum, high-temperature resistant copper coil.
Voltage: 220V and 380V (must be output through the frequency converter, can not directly use ordinary household electricity)

Features: motor torque, low noise, smooth speed, high frequency, stepless speed regulation, no-load current is small, slow heating, fast heat dissipation, easy to use, long life.
Two types of spindle motors
(a) electric spindle motor can be divided into air-cooled electric spindle and water-cooled electric spindle.
1, air-cooled spindle: the price cost is higher than the water-cooled spindle, mainly used in woodworking engraving machine, in the northeast of China is more applicable, because that winter is too cold water-cooled spindle is easy to ice, frozen pipe, air-cooled spindle will not make the engraving machine users have this kind of trouble. Good quality air-cooled spindle motor is mainly imported.
2, water-cooled spindle: this spindle in the domestic advertising engraving machine, wood engraving machine, jade engraving machine and stone engraving machine, tombstone engraving machine on the use of more common, mainly because of the cost of such a spindle is more moderate to be able to fit the majority of domestic manufacturers and strong stability, mature technology, the bad loss rate is not very high.
(B) air-cooled spindle and water-cooled spindle difference and connection
Customers in the choice of spindle motor, will be thinking: in the end is good air-cooled, water-cooled good? So it is necessary to figure out the difference between the two links.
1, air-cooled spindle and water-cooled spindle **** the same point:
In terms of the internal structure, the two are unified, are the use of electronic winding coil rotation; from the motor control, water-cooled are basically used inverter control, and air-cooled can be used inverter and non-inverter two ways.
2, air-cooled electric spindle and water-cooled electric spindle difference:
(1) water-cooled is the use of water circulation to cool the spindle to tell the heat generated by the rotation. This effect is better, because the general water circulation generated by the temperature will not exceed 40 degrees; air-cooled mainly using the fan to dissipate the heat, the effect is certainly not as good as water-cooled;
(2) on the noise, water-cooled basically no noise, while the noise of air-cooled will be more obvious.
(3) service life, water-cooled usually pay attention to maintenance, diligent water change, or the use of industrial water-cooled machine, the service life than the air-cooled a lot longer.
(4) precision, water-cooled spindle axial and radial runout are basically below 0.003 mm, much higher than the accuracy of air-cooled.
Three, the spindle motor brand and main models
1, brand: with the development of science and technology, the motor's technological innovation is also changing day by day. Now in the market motor is mainly divided into domestic brands and foreign brands
Foreign brands are: Japan's Mitsubishi, Yasukawa, Sanyo, Panasonic and Fuji, etc., Germany's Siemens, Germany SCHORCH (Germany SCHORCH) motors, the U.S. GROSCHOPP motors, Switzerland, ABB
Domestic brands are: Jiamusi motors, Xiangtan motors, Hong Kong, Tak Cheong motor, Shanghai motor, Harbin motor; Nanyang motor, Shanghai Nanyang motor, Changzhou BaoLai electrical, Changsheng water-cooled spindle motor in the engraving machine is more widely used.
In the past quite a long time, China's motor mainly rely on foreign brands. And after a lot of hard work, domestic motors have developed rapidly, and have fought for a place in the motor market.
