In a modern society with rapid technological progress, spindle motors have become very popular throughout the country and the world, thanks to their meticulous processing, speed, and high processing quality, which is not possible with other ordinary motors.
The spindle motor is also called a high-speed motor, which refers to an AC motor with a speed of more than 10,000 rpm. Mainly used in wood, aluminum, stone, hardware, glass, PVC, and other industries. Spindle motors have the advantages of high speed, small size, lightweight, less consumables, low noise, and low vibration, and are increasingly valued and applied by related industries.
The windings of a high-speed electric spindle motor are 120° out of phase. When energized, the three-phase windings each form a sinusoidal alternating magnetic field. The magnetic field rotates at a constant speed in a certain direction and the speed of the magnetic field is the synchronous speed of the motor spindle. The synchronous speed of an asynchronous motor is determined by the frequency of the current input to the motor stator winding and the number of pole pairs in the motor stator. The electric spindle obtains its various speeds by varying the frequency of the current input to the motor stator winding and the excitation voltage. As the direction of the rotating magnetic field of the motor depends on the phase sequence of the three-phase alternating current input to the stator, changing the phase sequence of the input current to the electric spindle can change the direction of rotation of the spindle.
Spindle motors are classified in various ways, and different classification methods will divide them into different types. Two classification methods are mainly introduced here, cooling method and tool changing method. Spindle motors can be divided into two types: cooling spindle motors and water-cooling spindle motors according to different cooling methods. According to the different ways of tool change, it can be divided into manual tool change spindle motor and automatic tool change spindle motor.
The above is the introduction of some knowledge about the spindle motor. I hope that after reading this article, it can help you have a simple understanding of the spindle motor. Other knowledge about the spindle motor will be added in later articles, such as how to choose a suitable spindle motor, the principle and technology of spindle motor design, etc. If you are interested in spindle motors, welcome to follow us, we will continue to provide you with information on spindle motors.
