Abstract

The invention discloses a direct current brushless motor, comprising a motor shell; a left end cover and a right end cover are fixedly connected to two ends of the motor shell; four peripheral magnets are evenly and fixedly connected to the inner surface of the motor shell; a first rail, a second rail, a third rail and a fourth rail are fixedly connected to the inner surface of the peripheral magnets; the peripheral face of a roll sphere is in rolling connection between the first rail and the second rail and is also in rolling connection between the third rail and the fourth rail; a central roller is in rolling connection with the inner circumference face of the roll sphere; a central magnet is sleeved in the central roller; one end of the central magnet is fixedly connected with the left end cover; the magnetic pole of the central magnet is opposite to those of the peripheral magnets; the first rail and the fourth rail are connected with the positive pole of a power supply; the second rail and the third rail are connected with the negative pole of the power supply. The motor has no brush; the mechanical friction loss is little; the efficiency is high; the noise is low; and no spark is generated.

Description

technical field [0001] The invention belongs to the field of motors, in particular to a DC brushless motor. Background technique [0002] Because traditional DC motors use brushes to commutate mechanically, there is relative mechanical friction, which brings about weaknesses such as noise, cremation, radio interference, and short life, plus high manufacturing costs and difficult maintenance. disadvantages, which greatly limit its scope of application. Contents of the invention [0003] The object of the present invention is to provide a DC brushless motor aiming at the deficiencies of the above-mentioned prior art. [0004] Technical scheme of the present invention is realized in the following manner: [0005] The DC brushless motor includes a casing, the two ends of the casing are fixed with a left end cover and a right end cover, and the inner surface of the casing is evenly consolidated with four outer peripheral magnets, and the inner surface of the outer peripheral ...
