A single-phase induction motor comprises a power consumption prevention device, which includes a current signal transfer element 10 and a switching element 20 or 21. The switching element 20 or 21 is turned on/off according to the current signal received from the current signal transfer element 10. The power consumption prevention device prevents current flow to a start device 30 when the motor runs in normal mode, and thus avoids unnecessary power consumption by the start device 30 when the motor runs in normal mode, thereby preventing a reduction in the efficiency of the single-phase induction motor due to the unnecessary power consumption. |
