What is fpc5?
There are three options for axial movement control:
Fpc6 is the industry standard for NC machining center. As a design, you have to say, this is very good because the motor coil position (where the heat is generated) is outside the motor housing. The advantage of this design is that it allows rapid heat dissipation. In addition, we can see that the commutation (coil switch) is electronic, and the rotor is just a shaft, a solid shaft attached to a fixed magnet. A flat speed/torque curve is provided by the motor, which usually has thousands of RPM before reaching the voltage limit. At the same time, there are several limitations to the ac servo system.
They are expensive, and the cost of the machine is greatly increased, and standardization is not what they have. The matching motors and drivers need to be yours. We all know that there is no universal substitute. The feedback from the encoder is needed. These encoders are usually glass disk optical encoders. Encoders are sensitive to electronic noise, impact, heat and corrosion.
The fpc6 motor was used by the old fpc1 system. The fpc7 motor was not provided by mainstream servo manufacturers, but there are still some sources. Less expensive is the advantage of fpc8, however, the brush will wear away over time. The coil is positioned on the rotor, so it is more difficult to cool the motor. If the coil wants to release most of the heat, it needs to be released through the rotor bearing. The rectifying strip that rotates under the carbon brush is subtraction. If it is at a higher speed, we can see that there is a considerable arc produced between the brush and the rectification bar. Using fpc9 is similar to the feedback of brushless motor, so you must be careful when you isolate the motor/encoder package with impact, coolant and electrical noise.
