Single Phase Brushless Motor And Electric Apparatus
A single phase brushless motor and an electric apparatus 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 at least two teeth. The tooth includes a tooth body and a tooth tip. The tooth tip includes first and second pole shoes. The rotor is received in a space defined between the first pole shoes and the second pole shoes. Each tooth forms a positioning groove facing the rotor between the first pole shoe and the second pole shoe. The first and second pole shoes are symmetrical about a central line of the tooth body and the positioning groove deviates toward the first pole shoe, such that the rotor startup capability in one direction is greater than the rotor startup capability in an opposite direction. The single phase motor has a larger startup torque with enhanced startup capability.
