GoHz 5hp single phase VFD wiring instruction for single phase induction motor
Single phase induction motor has specific wiring requirements in connecting with GoHz 5 hp single phase variable frequency drive to enable your single phase motor running properly, please follow below instructions step by step:
GoHz VFD wiring for single phase induction motor

Single phase motor has one or two capacitors, disassembly them. The VFD output can't have capacitor.
VFD Common Terminal: Running GoHz 5hp VFD at 50Hz without connecting loads, measuring the output voltages of U-V, U-W, and V-W, two of three voltage values are the same, their common port is VFD's common terminal. Usually the default common terminal is V phase. (The output voltage is a bit higher for the non-common terminal)
Single phase motor has 3 windings and 6 taps. Base on the measuring results of the resistance by a multimeter, the biggest resistance is the secondary winding (Z1, Z2), the smaller resistance is the main winding (U1, U2), the smallest resistance (conducting) is centrifugal switch (V1, V2).
The Coupling End of the single phase motor secondary winding (Z2) and main winding (U2) is connected to GoHz 5 hp VFD's output common terminal (V phase).
The Coupling End of the single phase motor main winding (U1) and centrifugal switch (V1) is connected to GoHz 5 hp VFD's U phase. The Coupling End of the secondary winding (Z1) and capacitor is connected to the VFD's W phase. In case of the induction motor running in reverse, please exchange the VFD's U phase and W phase.
