A rotor includes a yoke, an end cap, and a rotary shaft. The yoke is fixed relative to the end cap. The rotary shaft extends into the yoke. One end of the rotary shaft is connected to the end cap. The end cap is formed on the yoke and the rotary shaft by injection molding. The present invention further provides a motor and an electric tool including the rotor. In the rotor of this invention, the end cap is formed by injection molding, and the yoke and the rotary shaft are connected into a whole at the same time of forming the end cap. The traditional aluminium end cap is replaced with the molded end cap, which makes the rotor easier to fabricate and have a lighter weight and lower cost.
A brushless direct current motor, a stator part and its winding method are provided. The stator part includes a stator core and stator windings wound around stator poles. The stator poles and the stator windings are arranged in a one-to-one correspondence with each other. The stator windings are formed by winding a single conductive wire uninterruptedly on the stator poles. Two ends of the conductive wire are connected.
A motor driving circuit, the motor itself, and a motor driving method are disclosed. The circuit includes a controllable bidirectional alternating current (AC) switch and a processing unit, a voltage polarity of the AC power source and zero voltage crossing point of an AC power source being detected, together with a magnetic pole position of a permanent-magnet rotor, to govern the operation of the AC switch. When the controllable bidirectional AC switch is to be switched on, a trigger pulse is output after a delay time after the zero voltage crossing point, such that a phase difference between a back electromotive force and current flowing through the stator winding is decreased.
