Embodiment 1

[0019] The electric motor of the parallel structure of present embodiment, see figure 1 , figure 2 ; Including rotor 1, permanent magnet 2, coil 3, carbon brush 4, shell 5. Three coils 3 are evenly distributed around the rotor 1 in a triangular shape. The coil 3 is fixedly connected with the rotor 1 and rotates together with the rotor 1 . The three coils 3 are connected in parallel to the battery through carbon brushes 4 . Two sets of permanent magnets 2 are installed at both ends of the coil 3 , the upper end is N, the lower end is S, and the magnetic field lines pass through the coil 3 . Two groups of permanent magnets 2 are fixedly connected with the shell 5 .

Embodiment 2

[0021] The electric motor of the parallel structure of present embodiment, see image 3 In the axial direction of the rotor 1, two sets of three coils 3 and two sets of two pairs of permanent magnets 2 can be stacked together. When the installation space is narrow and long, such a structure can obtain a relatively large torque.

Abstract

The invention relates to a motor with a parallel platform, which solves the problem that the original structure of the motor has a bigger magnetic gap. The motor comprises a rotor, coils, excitation systems and an outer shell, wherein the coils are fixedly connected with the rotor; central axes of the coils are parallel with a central axis of the rotor; the amount of the coils is 1-N; the excitation systems are arranged at two ends of the coils and are fixedly connected with the outer shell; and the amount of the excitation systems is 1-N pairs. The motor with the parallel platform effectively reduces the magnetic gap of the motor so as to improve the electrical efficiency of the motor, and improve the torque and the rotating speed of the motor in a limited space.

Description

technical field [0001] The present invention relates to an electric motor, and more particularly, the present invention relates to an electric motor having a parallel configuration. Background technique [0002] At present, in known electric motors, the center line of the coil is perpendicular to the axis of the rotor of the motor, and the permanent magnets are arranged on both sides of the axis of the rotor. The advantage is that the structure is simple and the manufacture is convenient. The disadvantage is that due to the existence of a large magnetic gap, the electrical efficiency is low, and the electrical efficiency is generally below 80%. In the case of limited motor space or battery power supply, how to improve the electrical efficiency of the motor is of great significance to improve product competitiveness. [0003] The Chinese Patent Office published a document CN1222002A on July 7, 1999, named as a permanent magnet motor. The invention provides a permanent magnet...
