GoHz 3 hp single phase VFD wiring instruction for single phase induction motor
Single phase induction motor has specific wiring requirements in connecting with GoHz 3 hp single phase variable frequency drive to enable your single phase motor running properly, please follow below instructions step by step:
- Single phase motor has one or two capacitors, disassembly them. The VFD output can't have capacitor.
- VFD Common Terminal: Running GoHz 3 hp 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 3hp 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 3hp 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.
