Problems solved by technology
[0004] In the traditional motor manufacturing technology, the two wire ends on each tooth of the stator core are all connected by a printed circuit board, which will lead to too many holes on the printed circuit board and too many pads connected to the wire ends (refer to figure 1 ), causing the printed wiring of each phase to be too narrow. When the motor current is large, the printed circuit board will overheat and cause a safety accident

Embodiment approach
[0048] In a more specific embodiment, the embodiment of the present invention is described with a structure diagram of a motor wound with windings, such as figure 2 As shown, it is a 4-pole 12-slot motor. In the traditional winding method, 12 winding coils 5 are wound separately, and finally there are 24 enameled wire ends (terminal 6), and there are 24 corresponding printed circuit boards. corresponding connection holes. As an embodiment of the present invention, the windings V1 and V2, the windings V7 and V8 of the V winding group can be wound with the same wire respectively, or the windings V1, V2, V7 and V8 can be wound with the same wire; The windings U3 and U4, the windings U9 and U10 of the winding group are respectively wound with the same wire, or the windings U3, U4, U9 and U10 are wound with the same wire; the windings W5 and W6 of the W winding group, the winding W11 and W12 are respectively wound with the same wire, or W5, W6, W11 and W12 are wound with the same...

The invention is suitable for the technology of motors, and provides a motor and a manufacturing method thereof. The motor comprises a stator, 3*N coils which are wound on the stator, and a circuit substrate which is connected with the coils. An integrated winding of U, V and W three-phase windings is formed by the coils. The coils of the same phase are mutually connected in series and / or connected in parallel so that two end points are formed. The two end points are connected with the circuit substrate. Therefore, the end points for connection of the windings and the circuit substrate are reduced, connecting holes for connection with the end points of the windings on the circuit substrate are reduced, printed wiring area for electric connection with the winding of the corresponding phase is increased, and thus overheating and even a safety accident do not occur on the circuit substrate even motor current is quite high.
Description
technical field [0001] The invention belongs to the field of motor manufacturing, and in particular relates to a motor and a manufacturing method thereof. Background technique [0002] In the permanent magnet motor, the stator winding generally adopts distributed winding or concentrated winding. Compared with the distributed winding stator, the concentrated winding stator requires the stator core of the motor to be divided. The torque is small, the length of the end connection is short, and the winding of the split iron core is more convenient. Concentrated windings have been widely used in permanent magnet motors. [0003] With the development of general-purpose permanent magnet servo motors, the application industry is becoming more and more extensive, and the requirements for servo motors are becoming more and more stringent. In some high-end applications, such as robots, due to the limitation of installation space, the axial direction of the motor Size has strict requir...
