Specific embodiment
Applicant has found that Jing after research it is directly sealed that existing motor integration controller is generally power component MOSFET
To motor casing inner bottom part or by way of being installed on motor casing bottom after one radiates aluminium block switching, on the one hand dismounting is bothered,
On the other hand its area for taking shell can be very big, while the quantity that power component can be placed is directly affected, traditional motor
Integrated controller power can only typically accomplish 250W～350W or so, otherwise be accomplished by further increasing the overall volume of motor
More powerful possibility could be realized.
It is found by the applicant that：Some motor integration controllers by the way of two pieces of PCB, i.e. the mode of aluminium base+FR4,
To realize powerful requirement.And the PCB of aluminium base material on the one hand can only one side placing element, while price is than common FR4
Expensive half of base material or so.Simultaneously because aluminium base mode must be using the power component MOSFET of SMT encapsulation form, and same type
The MOSFET of SMT encapsulation typically can be higher by 2～3 times than the cost of traditional DIP encapsulation.And realize that the controller power of 500W will
Ask, generally require 12 MOSFET and can be only achieved.Power is bigger, and power component is more, and cost is also just higher.For this purpose, applicant
Technical scheme below is proposed, to solve relevant issues.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of electric motor car is with high-power integrated electric motor controller, including motor casing,
And the MOSFET components being arranged in motor casing.
Wherein, as shown in Fig. 2 motor casing 7 includes integrally formed inner shell 75 and shell, the inner shell is formed in an arc
Wall, the shell include that the first arc kink 71 for sequentially arranging, the second arc kink 72, first are caved in portion the 76, the 3rd
Arc kink 73, second are caved in portion 77 and notch part 74.An accommodation space is formed between the inner shell and shell, the accommodating sky
The side of interior, close inner shell is provided with radiating aluminium block erecting bed 9, and the opposite side of the inner shell is provided with fixed lobe 78.Institute
State radiating aluminium block erecting bed and there is at least two segmental arcs and the straightway between segmental arc；The MOSFET components include
Multiple MOSFET 2 (being 12 in the present embodiment), the radiating aluminium block 1 for installing the MOSFET, and with the MOSFET
The controller PCB 5 of connection；The radiating aluminium block includes integrally formed first segmental arc 101, the second segmental arc 103 and is located at first
Straightway 102 between segmental arc and the second segmental arc；First segmental arc and the second segmental arc are fitted with the arc on erecting bed respectively
Match somebody with somebody.
MOSFET is fixedly connected with radiating aluminium block by the 4th screw 8 (M3*6 round end machine tooth screws).Radiation aluminium block body
And end is provided with the through hole that is fixedly connected, respectively by the first screw 3 (M3*20 round end machine tooth screws), 4 (M3*8 of the second screw
Round end machine tooth screw) it is fixed on radiating aluminium block erecting bed.Controller PCB passes through the 3rd screw 6 (M3*6 round end machine tooth screws)
It is fixedly connected with motor casing.The shape of controller PCB is adapted with the formation of the accommodation space formed between inner shell, shell.Institute
