Through the Ethernet switch can be understood as the way in single phase motor which the port is crisscrossed circuit matrix between the telephone switchboard. It detected in the input port when a packet, check the package in baotou, for the purpose of the package address, start the internal dynamic lookup table into the corresponding output port, the intersections on the input and output, the packets through the corresponding port, realize the exchange function. ANP gost motor Because do not need to be stored, delay is very small, exchange, very fast, this is its advantage. Its disadvantage is that because the packet content has not been Ethernet switch, so can't check whether the transmission of packets is wrong, Single phase motor does not provide error detection ability. Since there is no cache, will not have different rate of input/output port connected directly, and easy to lost package.
This control strategy? For microcontrollers ST72141 adopted, the motor started by positioning to correct phase operation can arrange? Done, but must cooperate with the rotating inertia of the motor? And the load, the appropriate set some???? , just can make maximum ST72141 controller function. Figure 3.1 shows the motor start to seek after the registration, and then accelerate, the stable running and stop. Figure 3.2 as accept to start the motor life? After the motor starts to mandatory synchronization mode (forced synchronous mode), synchronization is this? In mode (synchronous switched mode) of the previous step, this process has been to the motor rotation speed is fast enough, namely? / event (Z - event), the point is over, to avoid the counter electromotive force is too weak?? Detection. Synchronization? In mode during the first work is motor of departure wholesalemotor.blogspot.com to the (startup), then the first counter electromotive force detection? Pay more to accelerate the motor gradually. If small diesel generator be in starting and accelerating (ramp - up) before the end of the haven't detected? Pay the point fan cover events, the motor will automatically stop. Then the motor into the synchronization? In mode (synchronous switched mode) and then into the automatic? In mode (auto - switched mode).
