Brushless DC motor using magnet magnetic force and only one solenoid

The invention relates to a brushless DC motor using a magnet magnetic force and only one solenoid and application of the motor in power equipment. An attractive force and a repulsive force exist between the magnets, as well as a third force, namely a magnet magnetic force. In a rotor, a motor and a permanent magnet brushless motor only use magnets. In a stator, a permanent magnet brushless motor only uses a plurality of solenoids, and does not use magnets. The motor of invention only uses one solenoid and a plurality of magnets. The motor utilizes the magnet magnetic force generated between a static magnet and a moving magnet as a driving force, and simultaneously uses the magnet magnetic force generated between the solenoid and the moving magnet as a driving force, and the rotor starts rotating only using one solenoid. The brushless DC motor generates magnet magnetic force and reduces attraction and repulsion, greatly reducing the use of external power and improving efficiency. 利用磁石磁力的只用个电磁线圈的无刷直流电机是在动力设备中的应
