A single phase brushless motor and a power tool and a car window lifer employing the motor are provided. The motor includes a stator and a rotor. The stator includes a stator core and windings. The stator core includes a yoke and teeth extending inward from the yoke. The tooth includes a tooth tip. The tooth tip includes a first pole shoe and a second pole shoe. The tooth tip forms a positioning groove facing the rotor between the first and second pole shoes. The rotor is received in a space defined between the first and second pole shoes. The rotor comprises multiple permanent magnetic poles arranged in a circumferential direction of the rotor. The first and second pole shoes are symmetrical about a central line of the tooth body, such that the rotor startup capability in one direction is greater than the rotor startup capability in an opposite direction.
