Embodiment Construction
[0005] Embodiments of the present invention mainly contain the following contents:
[0006] 1. Coil ( figure 1 The dotted circle marked 1 in the middle) is fixed on the outer stator ( figure 1 On the solid line circle marked as 4 in the middle), it is convenient for heat dissipation, and at the same time, it is convenient for power supply to solve the unstable contact of the brush.
[0007] 2. By bar magnet ( figure 1 The strip fan blade marked as 3) is fixed on the rotating shaft ( figure 1 The area marked 2 in the middle) constitutes the rotor, the rotating shaft is connected with the magnetic poles of the same sex of the magnet, and the magnetic poles of the outer ends of each fan blade of the rotor should be the same.
[0008] 3. Will figure 1 The area marked 6 in the middle section is enlarged to illustrate the starting and working principle of the motor. The two terminals 17 and 18 of the motor are connected to the two stages of the DC power supply. According to Len...

The invention discloses a rotating magnetic pole type brushless direct current motor, and belongs to general machines or engines in the technical field of mechanical devices and transportation. The classification number of the rotating magnetic pole type brushless direct current motor is F01M. At present, a direct-current motor is wide in application and gradually becomes a main power output source of people, but the development of the motor is limited due to the reasons of motor heat dissipation, unstable electric brush work and the like. Based on the problems, the rotating magnetic pole type brushless motor well solves the two problems. According to the invention, the purposes of heat dissipation of the motor and no use of an electric brush are achieved by fixing a coil and rotating a magnetic pole. The rotating magnetic pole type brushless motor works based on the basic principle that an electrified wire is stressed in a magnetic field. Mainly by utilizing the Newton's third law, a coil is fixed on a stator, a magnetic pole is fixed on a rotor, and the magnetic pole is pushed to rotate due to the counter-acting force of stress of a wire in a magnetic field.
Description
Technical field: [0001] The rotating magnetic pole brushless DC motor belongs to the general machine or engine under the field of mechanical equipment and transportation technology, and the classification number is F01M. Background technique: [0002] At present, DC motors are widely used and have gradually become the main source of power output for people. However, the development of motors is limited by reasons such as motor heat dissipation and unstable operation of brushes. Based on the above problems, the rotating magnetic pole brushless motor solves these two problems well. Invention content: [0003] The invention achieves the purpose of solving the heat dissipation of the motor by fixing the coil and rotating the magnetic pole without using electric brushes. The rotating magnetic pole brushless motor works on the basis of the force of the current-carrying wire in the magnetic field. Mainly by using Newton's third law, the coil is fixed on the stator, and the magn...
