[0026] The utility model makes further explanation from the following combined with the drawing and embodiment.

[0027] First embodiment

[0028] Referring to Figs. 1-3 The utility model discloses a motor electric control two unification assembly, including motor 1 and electric control 5, motor 1 includes casing 101, and the opening of casing 101 is equipped with end cover 103, and the inside of casing 101 is equipped with stator module 102 and rotor module, and stator module 102 and rotor module are connected through bearing and axle center, and rotor module can rotate freely inside stator module, and electric control 5 is equipped with heat dissipation bottom shell 501 on it;

[0029] Stator module 102 is equipped with a plurality of terminal, and end cover 103 is equipped with wire holder 3 of electric connection of terminal on stator module 102;

[0030] The outside of motor 1 output shaft is equipped with rotary variable part 2, and rotary variable part 2 is connected with electric control 5 through cable, and rotary variable part 2 works synchronously with rotor module, and obtains rotor angle information;

[0031] The outer wall of electric control 5 is equipped with positive and negative busbar terminal block 502 for power supply, and one side of electric control 5 towards motor 1 is equipped with copper bar assembly 4, and copper bar assembly 4 is electrically connected with wire holder 3;

[0032] Copper bar assembly 4 and wire holder 3 electrically plug, can receive the transmission rotating speed, steering and other measurement data information of rotary variable device 2, and electric control 5 according to the measurement data information received, utilizes the electric connection of copper bar assembly 4 and wire holder 3 to transmit the signal handled to the stator module 102 of motor 1, to control the operation of motor 1.

[0033] In the device, the motor and electric control are separately arranged, so that the heat generated by the motor does not affect the electric control, and the cooling structure can be separately arranged according to different heating positions.

[0034] The electrical connection between the electric control and the motor is achieved by the electrical connection of the copper bar assembly and the wire holder, which greatly reduces the connection complexity between the motor and the electric control, reduces the installation difficulty and time cost, and improves the production efficiency.

[0035] The second embodiment differs from the first embodiment in that:

[0036] The wire holder 3 includes a fixed seat 302 connected to the end cover 103. The fixed seat 3 is a frame structure with a certain thickness, and a boss for auxiliary fixing is arranged on the outer wall. The fixed seat 302 can be fixedly connected with the end cover of the motor by means of bolts, buckles or welding. A plurality of through grooves corresponding to the electrical connection socket 301 are arranged on the frame structure. The inner end of the electrical connection socket 301 is electrically connected with the terminal on the stator module 102. A concave ring is arranged on the inner wall of the through groove. The inner side of the concave ring is fixed with the electrical connection socket 301 by means of an O-ring.

[0037] The fixed seat 302 can be made of stainless steel or plastic such as reinforced nylon. When high mechanical strength, corrosion resistance and good thermal conductivity are required, metal materials such as stainless steel are usually used to meet the requirements of durability and stability. For some light equipment or environments with high requirements for corrosion resistance, plastic materials with high corrosion resistance such as reinforced nylon can be selected.

[0038] The material of the electrical connection socket 301 is copper alloy or silver-plated copper. Copper has very good electrical conductivity and low resistance, so it can ensure low resistance and low loss during electrical conduction. The selection of copper alloy or silver-plated copper as the material of the electrical connection socket 301 can ensure low contact resistance.

[0039] The material of the O-ring is rubber, fluororubber, silicone, etc. The O-ring requires good elasticity and sealing performance. Rubber and fluororubber usually have good elasticity and chemical corrosion resistance, so they can ensure the buffering effect when the motor 1 works and ensure the stability of the electrical connection between the wire holder 3 and the copper bar assembly 4.

[0040] The material of the snap spring is stainless steel or spring steel. The good rigidity and durability of stainless steel and spring steel can ensure the recovery ability and the fixing effect.

[0041] In addition, the copper bar assembly 4 includes an electrical plug rod 401 and a base 402. The outer end of the electrical plug rod 401 corresponds to the electrical connection socket 301 one by one and matches each other. The inner end of the electrical plug rod 401 is electrically connected with the electric control 5. After the outer end of the electrical plug rod 401 is inserted into the electrical connection socket 301, the electrical connection between the electric control 5 and the motor 1 is realized. The base 402 is used to assist the electrical plug rod 401 to be fixed and installed on the outer side of the electric control 5.

[0042] The electric plug 401 is a cylindrical or conical structure, which is matched with the electric connection socket 301 in structure and electric connection. The surface of the electric plug 401 is knurled, which increases the contact area. The knurling can form rough patterns on the outer surface of the electric plug 401, increase the friction of the surface, enhance the contact stability and wear resistance with the electric connection socket 301, and improve the contact performance between the electric plug 401 and the electric connection socket 301. In the case of electric connection, good contact performance can reduce the resistance and improve the conductivity, thereby improving the electrical performance.

[0043] In the preferred embodiment, the electric connection socket 301 has a plurality of conductive contacts or contact springs inside. The outer wall of the electric plug 401 is in electric contact with the conductive contacts or contact springs of the electric connection socket 301, which ensures the transmission of electrical signals or current. This structure can ensure that the connector has reliable conductivity and is suitable for applications that require stable current and signal transmission. Moreover, the plurality of conductive contacts or contact springs inside the electric connection socket 301 provides multiple contact points, which increases the contact area, reduces the contact resistance, improves the reliability of the electrical connection, and effectively reduces the loosening or unstable contact that may occur during plugging.
