Description

Technical Field

[0001] The invention relates to a motor, and in particular to a novel motor winding method for winding a motor and a motor assembly thereof. Background Art

[0002] Usually, motors are produced and used in many fields. One of the main production process links in the production process of motors is the winding process of the motors. The winding method of the motor winding process will also bring about changes in factors such as motor performance or cost. However, the existing motor winding has quality problems such as the large space occupied by the brush rack assembly wiring, which is prone to cause the risk of wire breakage. Figure 4 As shown, the enameled wire is wound in a regular sequence from the 1st slot to the 3rd slot and then directly connected to the 2nd hook of the commutator. Summary of the invention

[0003] The present invention aims to solve the existing problems that the wiring of the brush holder assembly occupies a large space and is prone to quality problems such as wire breakage in the existing motor winding, and provides a new winding method for a four-pole motor and a motor assembly which can save wiring space on the brush holder assembly, reduce the risk of wire breakage, and improve the quality of motor winding.

[0004] The specific technical solution adopted by the present invention to solve the above technical problems is: a novel winding method for a four-pole motor, characterized by comprising the following winding execution steps:

[0005] A1. Perform the winding between the first hook and the first slot of the commutator, and the enameled wire is wound from the first hook of the commutator to the first slot;

[0006] A2. Wind the enameled wire from the 1st slot to the 3rd slot, with n turns;

[0007] A3. After executing the above step A2, the enameled wire is directly wound from the 3rd slot to the 6th slot;

[0008] A4. After executing the above step A3, the enameled wire is wound from the 6th slot to the 8th slot, and the number of turns is n;

[0009] A5. After completing the above step A4, the enameled wire is directly connected to the sixth hook of the commutator;

[0010] A6. After executing the above step A5, the enameled wire is connected from the 6th hook to the 1st hook;

[0011] A7. Following the winding rules of steps A1 to A6 above, the second hook starts to perform the winding between the remaining number of hooks and slots according to the above rules until all windings are completed;

[0012] The letter n in the above steps is a natural number.

[0013] The function of four brushes is realized by the rotor winding method of short-circuiting the diagonal winding, which saves the number of parts used in the motor assembly, reduces the product manufacturing cost, saves space on the brush holder assembly, makes the wiring safer, more reliable and effective, and improves the motor winding quality.

[0014] Preferably, each hook body on the commutator has only two enameled wires hooked on it. In the conventional winding method of the motor in the prior art, at least three enameled wires are hooked on each single hook body of the commutator, while the present invention can achieve that only two enameled wires are hooked on each single hook body of the commutator through the winding method, which not only reduces the winding space required for the number of enameled wires on a single hook body, but also reduces the risk of enameled wire breakage caused by this, thereby improving product manufacturing and service life.

[0015] Another invention purpose of the present invention application is to provide a new winding motor assembly, including a brush holder assembly and a motor rotor equipped with multiple winding grooves and corresponding winding hooks, characterized in that: the motor rotor adopts the new winding method described in one of the above technical solutions, the number of brushes on the brush holder assembly is 2, and the two brushes are arranged at an angle of 90 degrees to each other on the brush holder assembly. The function of four brushes is achieved by the rotor winding method of short-circuiting the diagonal winding, which saves the number of parts used for the brushes in the motor assembly, reduces the product manufacturing cost, saves space on the brush holder assembly, and is more convenient for safe, reliable and effective wiring.

[0016] The beneficial effects of the present invention are: the function of four brushes is realized by the rotor winding method of short-circuiting the diagonal winding, the number of parts used for the motor assembly using the brush is saved, the product manufacturing cost is reduced, the space on the brush holder assembly is saved, the wiring is more convenient for safety, reliability and effectiveness, and the motor winding quality is improved. The risk of enameled wire breakage caused by this is reduced, and the product manufacturing and service life are improved. BRIEF DESCRIPTION OF THE DRAWINGS
