Description

Technical Field

[0001] The present invention relates to the technical field of motor rotor winding, and more particularly to a motor rotor winding method. Background Art

[0002] Motor rotor: This is the rotating component in a motor. A motor consists of two parts: the rotor and the stator. It is a device used to convert electrical energy into mechanical energy and vice versa. Motor rotors are classified as either motor rotors or generator rotors.

[0003] The motor rotor needs to be wound so that it generates a magnetic field when powered, which interacts with the stator to rotate. The more turns the winding has, the greater the magnetic field generated.

[0004] The traditional winding method uses a winding method with the same number of slots between the motor rotor and the slot-type commutator, which increases the amount of winding wire consumed and the winding time, resulting in high costs. Summary of the Invention

[0005] The object of the present invention is to provide a method for winding a motor rotor.

[0006] The purpose of the present invention is achieved through the following technical solutions:

The slot commutator and the motor rotor rotate together along the motor rotor axis to form multiple loops. Suppose the slots of the slot commutator and the motor rotor that start winding are Xn and An respectively, and n is the number of slots of the slot commutator and the motor rotor, and n is greater than or equal to 1 and less than or equal to 10:

[0011] 1) When n is greater than or equal to 1 and less than or equal to 5, it starts from the Xnth slot of the slot-type commutator and passes through the A2n+1, A2n+5, A2n+2, A2n+4 of the motor rotor and then returns to the n+5th slot of the slot-type commutator;

[0012] 2) When n is greater than 5 and less than or equal to 10, it starts from the Xnth slot of the slot-type commutator and passes through the A2n+1th, A2n+5th, A2n+2th, A2n+4th slots of the motor rotor and then returns to the Xn-5th slot of the motor rotor;

[0013] Step 4: Cut the winding material and complete the winding of the motor rotor and slotted commutator.

[0014] Preferably, 20 slots are provided on the motor rotor.

[0015] Preferably, the slot-type commutator is provided with 10 slots.

[0016] Preferably, the slot-type commutator in step 2 is detachably connected to the motor rotor.

[0017] Preferably, the angle between the center line of the motor rotor and the center line corresponding to the slot-type commutator is 9°.

[0018] Preferably, in step three, the angle of the slotted commutator and the motor rotor rotating together each time is 72°.

[0019] Preferably, in step three, the motor rotor winding machine uses a single flying fork winding method.

[0020] Preferably, in step three, the motor rotor winding machine uses a double flying fork winding method.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0025] Figure 1 It is a winding schematic diagram of the present invention.

[0026] Figure 2 It is a connection diagram of the motor rotor and the slot-type commutator of the present invention. DETAILED DESCRIPTION

[0027] The present invention will be further described below with reference to the accompanying drawings.

[0028] like Figures 1 to 2 As shown,

[0029] A motor rotor winding method, the method comprising the following steps:

[0030] Step 1: Set up a motor rotor winding machine, a slot-type commutator, a motor rotor, and winding materials. The motor rotor is provided with 20 slots, and the slot-type commutator is provided with 10 slots. By making the number of slots of the slot-type commutator smaller than the number of slots of the motor rotor and using a new winding method to reduce the number of windings, the process cost can be reduced.

[0031] Step 2: Install the winding material, motor rotor and slot-type commutator on the motor rotor winding machine. The slot-type commutator in step 2 is detachably connected to the motor rotor. When the slot-type commutator is set on the motor rotor, the angle between the center line of the motor rotor and the center line of the corresponding slot-type commutator is kept at 9°, which can ensure that after the winding is completed, the commutator provides greater force for the motor rotor during commutation when the motor is running.

[0032] Step 3: The motor rotor winding machine starts to wind the winding material around the slot commutator and the motor rotor. The slot commutator and the motor rotor rotate together along the motor rotor axis to form multiple loops. Suppose the slots of the slot commutator and the motor rotor that start winding are Xn and An respectively, and n is the number of slots of the slot commutator and the motor rotor, and n is greater than or equal to 1 and less than or equal to 10:

[0033] 1) When n is greater than or equal to 1 and less than or equal to 5, it starts from the Xnth slot of the slot-type commutator and passes through the A2n+1, A2n+5, A2n+2, A2n+4 of the motor rotor and then returns to the n+5th slot of the slot-type commutator;

[0034] 1. Start from the 1st slot of the slot commutator and pass through the 3rd, 7th, 4th and 8th slots of the motor rotor and then return to the 6th slot of the slot commutator;

[0035] 2. Start from the 2nd slot of the slot commutator and pass through the 5th, 9th, 6th and 10th slots of the motor rotor and then return to the 7th slot;

[0036] 3. Start from the 3rd slot of the slot commutator and pass through the 7th, 11th, 8th and 12th slots of the motor rotor and then return to the 8th slot;

[0037] 4. Start from the 4th slot of the slot commutator and pass through the 9th, 13th, 10th and 14th slots of the motor rotor and then return to the 9th slot;

[0038] 5. Start from the 5th slot of the slot commutator and pass through the 11th, 15th, 12th and 16th slots of the motor rotor and then return to the 10th slot;

[0039] 2) When n is greater than 5 and less than or equal to 10, it starts from the Xnth slot of the slot-type commutator and passes through the A2n+1, A2n+5, A2n+2, and A2n+4 slots of the motor rotor in sequence before returning to the Xn-5th slot of the motor rotor; 1. It starts from the 6th slot of the slot-type commutator and passes through the 13th, 17th, 14th, and 18th slots of the motor rotor in sequence before returning to the 1st slot;

[0040] 2. Start from the 7th slot of the slot commutator and pass through the 15th, 19th, 16th and 20th slots of the motor rotor and then return to the 2nd slot;

[0041] 3. Start from the 8th slot of the slot commutator and pass through the 17th, 1st, 18th and 2nd slots of the motor rotor and then return to the 3 slots;

[0042] 4. Start from the 9th slot of the slot commutator and pass through the 19th, 3rd, 20th and 4th slots of the motor rotor and then return to the 4th slot;

[0043] 5. Start from the 10th slot of the slot commutator and pass through the 1st, 5th, 2nd and 6th slots of the motor rotor and then return to the 5th slot;

[0044] After completing either of the two winding steps, the winding process is continued by rotating the slotted commutator and the motor rotor together by 72° each time, thereby completing the winding pattern of the winding loop formed above.

[0045] There are two types of winding methods for motor rotor winding machines.

[0046] Option 1:

[0047] When the motor rotor winding machine uses a single flying fork method, the winding speed is 2500r / min, which is practical under conditions of large processing volume. It can speed up the winding efficiency while ensuring the winding quality. The disadvantage is that it uses a large power.

[0048] Option 2:

[0049] When the double flying fork method is used in the motor rotor winding machine, the winding speed is 2000r / min, which is practical under the condition of small processing volume. It can save energy while ensuring the winding quality. The disadvantage is that the processing speed is slower than the single flying fork winding.

[0050] Step 4: Cut the winding material and use the motor rotor winding machine to complete the stacking of the motor rotor and the slot-type commutator, thus completing the winding of the motor rotor and the slot-type commutator.

[0051] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope of the appended claims.

[0052] Although more terms are used herein, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the present invention. It is contrary to the spirit of the present invention to interpret them as any additional limitation.
