400 Volts 3 phase to 240 Volts Single phase Motor Answered
Hello we bought a cutter from Europe. It came with 400V 0.75W 3 phase motor. The motor has leads
W2, U2, V2
To convert to the 240 V single phase we jumped (W2,U1), (U2, V1), (V2,W1). We also put 50uf capacitor between (W2,U1), and (V2,W1) .See attached pictures.
However the motor starts and spins for about 5mins then it trips the breaker. The motor heats up .
Between (W2,U1) and (U2, V1) =240v
Between (W2,U1) and (V2,W1) = 370v
Between (U2, V1) and (V2,W1) =240v
We thought (W2,U1) and (V2,W1) = 370v was little high.
Also the resistance between winding W1W2 is 36 ohms, U1U2 20 ohms, V1V2 20ohms
Can someone help? I will really appreciate you help
