9.6 Field Applications of E-CAM
9.6.1 E-CAM Application on Winding Machine
In this application example we apply DVP-PM for controlling the auto bobbinless winding machine, which can be
used on winding air-cored coils of different specifications such as drive coils, speaker coils, antenna coils and
other common bobbinless coils. The winding system with DVP-PM has better reliability and is highly automated
with high working speed and efficiency as well. Therefore, it can achieve high quality results of batch production
of coils. Here are some of the coils:
Normal winding machines applly small PLCs with built-in pulse function. Though high speed input pioints, the
PLC receives pulses from the encoder of winding shaft, and roughly synchronizes the speed between the winding
