Single-phase electric hoist by twist wiring method
The motor of single phase electric hoist is not divided by the main side windings. Our company has eight or nine PA500 electric gourds that do not have a blessing winding. We've added a little road to the electric gourd and we've changed it ourselves. If you want to know if your motor is a partial primary, you can use a multimeter side resistance. One of the three lines coming out of the machine is the common thread, and the other two are the lines of two winding. If all the deputy Two windings into line and public end line resistance is big, if points main winding The main winding and the public side resistance than vice winding and the resistance on public. Also can see coming out of the motor line judge root number, if required by the main winding and were positive &negative coming out of the motor line to the root of the number of at least four. If it's 3, then you have to look at the number of roots that come out of the motor
The single-phase electric hoist method is as follows: There are three terminals and four terminals, and the capacitance of the three terminals can be connected to the starting winding of the motor and running the winding terminal. The four terminals are two terminals with the capacitance and the starting winding in series, which counts as two terminals.
Electric hoist is a kind of special lifting equipment, installed on the crane, gantry crane, electric hoist has small volume, light weight, simple operation, convenient use, etc, used in industrial and mining enterprises, storage terminals and other places. The weight is usually 0.1 ~ 80 tons, lifting height is 3 ~ 30 meters. It is composed of electric motors, actuator and drum or sprocket, which are divided into two kinds: wire rope electric gourd and chain electric gourd.
