What is water-cooled spindle CNC motor?
It means that the cooling water circulation is designed inside the spindle motors, and the corresponding cooling machine is equipped outside so that the cooling liquid circulates inside the spindle to take away the internal heat. The advantages of this cooling method are simple and reliable in design, and the cooling effect is more obvious.
Water cooled spindle motor vs. air cooled spindle motor
Heat dissipation method: The water-cooled spindle motor uses water circulation to cool the heat generated by the high-speed rotation of the spindle. This method works well because the temperature after circulation will not exceed 40 degrees. The air-cooled spindle motor uses a fan to dissipate heat, and its effect is definitely not as good as water cooling.
Noise: The water-cooled spindle motor is basically silent, but the air-cooled spindle motor is very loud.
Service life: Because the water-cooled spindle motor needs to pay attention to maintenance, change the water frequently or use an industrial water cooler, its service life is much longer than that of the air-cooled spindle motor.
Accuracy: The axial and radial runout of the water-cooled spindle motor is basically below 0.003 mm, which is far less than the air-cooled spindle motor.
User experience: Since the water-cooled spindle needs to be connected to a water pump, a bucket is needed to hold water, and a water pipe needs to be connected, especially in the cold winter in the north, it is more likely to freeze. Some customers will find it more troublesome, but the air-cooled spindle will not have such use problems.
Why use VFD for spindle motor?
A VFD can make the motor soft start, and the impact on mechanical equipment is small.The starting current of the VFD is smaller than that of the contactor, and the more frequent the working condition, the more energy-saving. It can be infinitely variable, and it is easy to meet the work requirements of elevators and others requiring smooth speed.
It is convenient for automatic control. The VFD has external control and local control and can be selected at multiple speeds. With an encoder, the spindle motor can be accurately positioned, and the control is very portable. The internal protection is perfect, and variable frequency drives are equipped with various fault protection functions. When the spindle motor or power supply fails, it will actively report the fault, and at the same time output the on-off signal through the relay contact, which is convenient to cut off the external control contactor and output the warning signal.
