A no-power-consumption starter used for commercial refrigeration compressor motor, comprising: a current instrument transformer (L1), a bidirectional thyristor (T), an inductor (L2), a positive temperature coefficient (PTC) element, and a starting capacitor (C1). One end of a primary winding coil (1) and one end of a secondary winding coil (3) of the current instrument transformer (L1) and a T1 pole of the bidirectional thyristor (T) are connected to one end of an alternating current, the other end of the primary winding coil (2) of the current instrument transformer (L1) is connected to a motor main winding lead-out terminal (M), the other end of the secondary winding coil (4) is connected to a G pole of the bidirectional thyristor (T), the inductor (L2), the PTC element, and the capacitor (C1) are sequentially connected in series between a T2 pole of the bidirectional thyristor (T) and a secondary winding lead-out terminal (S), and a motor main and secondary winding combination lead-out terminal (L) is connected to the other end of the alternating current. The starter increases motor operation efficiency. |
