摘要：
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.
摘要（中）：
提供单相无刷电动机和电气设备。 电动机包括定子和转子。 定子包括定子铁芯和绕组。 定子芯包括轭和至少两个齿。 牙齿包括牙体和牙齿尖端。 齿尖包括第一和第二极靴。 转子被容纳在第一极靴和第二极靴之间限定的空间中。 每个齿形成面向第一极靴和第二极靴之间的转子的定位槽。 第一和第二极靴关于齿体的中心线对称，并且定位槽朝向第一极靴偏离，使得一个方向上的转子启动能力大于相反方向上的转子启动能力。 单相电机具有较大的起动转矩，启动能力增强。
