Motor stator assembly structure

The invention provides a stator assembly structure of an electric motor, in particular, the installation direction of the two carrier disks of each group is oppositely arranged, and the plurality of magnetic core groups are installed by using an automatic plug-in method, so that the overall weight can be reduced by the carrier plate, and With the magnetic core group installed to greatly reduce the amount of material used to save costs, thereby achieving higher efficiency and lower cost.

According to the current industry, the development of the industry is extremely fast. Many industrial automation equipments are increasing day by day. In the automation of the production line, the metropolis uses many motors for control, and the stability of the motor control determines the quality of the products, so the motor Widely used in a variety of industrial occasions, and even in the general home life, to bring business opportunities, comfort and convenience to users, due to the increasing use of motors, the power consumption is very considerable, so how to improve the efficiency of the motor, reduce power consumption In order to save costs, etc., it has been the focus of research that is urgently needed.

Furthermore, with the advancement and low cost of magnetic materials and electronic power technology in recent years, permanent magnet synchronous brushless motors with high efficiency and high power have gradually replaced traditional DC brush motors, induction motors, etc. Become a driving force for various technological products, such as aviation, vehicles, home appliances, renewable energy, precision industries and robots, while traditional electric motors are used in electric bicycles, light electric vehicles, and other related controllers used in vehicles. The combined efficiency will drop sharply as the torque output or speed increases, and cause power loss. The endurance is reduced, and only limited power output can be provided to maintain a certain efficiency. If a conventional electric motor capable of generating sufficient torque is used, it may be too large or difficult to install in a limited space, such as electric The space available in the wheel hub of the bicycle can only be installed with an electric motor that is not powered or overweight and cannot meet the actual application requirements.

The type of permanent magnet synchronous brushless motor can be divided into radial magnetic flux, axial magnetic flux and transverse magnetic flux according to the magnetic flux direction, wherein the transverse magnetic flux permanent magnet synchronous motor is mainly a transverse flux motor (Transverse Flux). Machine, TFM), and can be divided into TFM prototype, single-sided flat TFM, magnetic magnetic TFM (such as active rotor or passive rotor type magnetic TFM) and permanent magnet reluctance TFM, etc. The advantages of small length, low speed characteristics, high torque density, etc., are very suitable for products requiring high volume and low speed operation with high torque output. The transverse flux motor includes a rotor and a stator. a coil, and a plurality of staggered magnets and a flux concentrator are arranged on the rotor, and a coil is mounted on the stator, so that a current can be input into the coil, and a transverse magnetic force generated between the magnet and the stator core drives the rotor to rotate. The rotational speed is proportional to the frequency of the current in the coil, and the torque is proportional to the amplitude of the current in the coil, or the rotor is driven by an external force to exchange flux with respect to the stator, so that a current output is generated in the coil. Arrangement, the transverse flux motor can also be fixed by the rotor and the stator to become mobile commutated flux machine (Commutator Flux Machine, CFM).

Because the characteristics and size specifications of the stator magnetic permeability material of the transverse flux motor and the commutating flux motor are one of the main factors affecting the output torque, and reduce the torque, magnetic flux leakage and loss, etc., it helps to improve The operating efficiency of the motor, so the stator structure design is the key to determine whether the maximum output torque of the motor can be improved. Please refer to the thirteenth figure, where the stator set A is a stator part A1 having two opposite sides, and a plurality of stator teeth A2 are arranged in an annular arrangement at the periphery of the stator part A1, and a coil is arranged in a space formed at the inner side of the two stator parts A1 (not shown) Out, except that the stator portion A1 is formed by a single material (such as niobium steel, powdered metal, soft magnetic composite material, amorphous metal, iron cobalt alloy, etc.) to form a ring piece by processing, or it may be more The annular segments are formed by stacking by pressing, stamping, etc., which not only will not make the weight of the whole stator assembly A lighter, and will also generate excessive waste in the process of manufacturing the stator portion A1, so that the cost is difficult to reduce. It does not meet the production efficiency considerations. In addition, when the coil of the stator combination A inputs current, the plurality of stator teeth A2 of the stator portion A1 will induce a varying magnetic flux, and the stator portion A1 will form a surrounding motor shaft in the annular structure. The continuous closed electric circuit causes the voltage induced in the stator part A1 to decrease and the unnecessary eddy current and heat loss, etc., which will reduce the efficiency of the motor, and may even Resulting in failure or damage to the motor.

In order to improve the loss of internal induced voltage caused by the formation of the above-mentioned stator assembly A to form a continuous electrical circuit around the motor shaft, the manufacturer has changed the structural design of the stator portion A1 to interrupt the continuous electrical circuit therein, please refer to FIG. The stator assembly B is provided with two opposite stator portions B1 formed by a plurality of stacked stacks B11, and stator teeth B2 are disposed in the plurality of trenches B12 formed at the periphery of the laminated stack B11, and each of the two adjacent portions The laminated stack B11 is interlocked by the notch B13, and the coil B3 is disposed between the two stator parts B1, so that the plurality of notches B13 (such as gaps, spaces, sections) can be completely penetrated through the stator part B1. Etc.) to interrupt the continuous electrical circuit within it to reduce the loss associated with the induced voltage in the stacked stack B11. The stator portion B1 is formed by splicing a plurality of stacked stacks B11, and the single sheet of the stacked stack B11 is No need to form An annular piece to reduce excessive material waste at the center of the annular piece, but the multiple laminated stack B11 has a ring structure after completing the stator part B1, and still cannot effectively reduce the weight of the whole stator assembly B, and the stator part B1 can only be assembled by hand. It is not only time-consuming and labor-intensive, but the overall production efficiency is poor. It can't be produced in large quantities in response to the automation of the production line and the process requirements. The cost required for the manufacture of the stator assembly B is relatively high. This industry is eager to study the key to improvement.
