Common enamel-covered wire kelvin effect under the big electric current of high frequency is obvious, and in the case of high-power, copper loss and heating are the most prominent.According to
This, it is thus proposed that use superconductor to reduce the scheme of copper olse, but, the high-critical temperature of present superconductor is
150K, i.e.-123 DEG C, the superconductor worked under ultralow temperature is obviously not suitable for popularization and application.
On the other hand, the used material of stator core is mainly traditional stalloy, due to the change of magnetic flux in stator core
Change frequency to be directly proportional to the rotating speed of motor, and specific loss consumption is proportional to the 1.3 of frequency～1.5 powers, so stalloy group
Rising along with frequency is dramatically increased by the loss becoming stator core.According to measuring and calculating, frequency be 50Hz, magnetic flux density be
Under 1.0 T, the loss of silicon steel stator core is less, only 1.4W/kg, and along with the rising of frequency, the loss of stator core is the biggest
Amplitude raises.When frequency be increased to 1 kHz, magnetic flux density be 1.0 T time, the loss of silicon steel stator core increase to 102W/
kg.Such as, a rotating speed is the motor of 60000r/min, when stator core changes of magnetic field frequency is 3000 r/min, motor
Unit iron loss will increase by 50～80 times, for reducing high-frequency loss unshakable in one's determination, can use the magnetic flux density or employing reduced in iron core
The method of low-loss core material.
From a structural point, existing permanent-magnet brushless DC electric machine at least should carry out significant improvement in terms of four: one
It is to change motor body in frame for movement to separate the present situation of use with controller, it is achieved permanent-magnet brushless DC electric machine and controller

Exhibition trend；Two is single-chip microcomputer rather than the DSP using efficient double-core on circuit topological structure, both can ensure in speed that motor is high
Speed is operating the most effectively to be controlled, and can be substantially reduced again device cost simultaneously；Three is to change to use in heat radiation topological structure to pass
The traditional design of system FR4 printed substrate, by using the printed substrate of high duty metal base, improves external conduction of heat
Rate, it is not necessary to fan, directly reduces the heat sink temperature of high-power V metal-oxide-semiconductor；Four is to change hall position sensor to pass through manual setting
Assembling is embedded in the custom of winding unshakable in one's determination, is directly welded on the printed substrate of Metal Substrate, and this is to simplify brushless, permanently
Direct current generator production technology, improves Hall orientation sensing accuracy and the preferable measure of production efficiency.
Obviously, after motor body and controller unite two into one, the most derivative problem made new advances: is how to allow motor originally
The effective combination on space structure is realized between body and controller；Two is how to dispose both integrated rear serious heat radiations to ask
Topic；Three be by what method realize energy-saving and cost-reducing to reach system and save most, the effect of total optimization.

Here it is noted that the method for traditional electric machine controller power device heat radiation has two kinds, one is directly to use
Copper Foil printed wiring board dispels the heat, the most common FR4 printed substrate, but for electric machine controller, big electric current
FR4 printed substrate is made to be difficult to bear high heat with powerful drive circuit, because the thermal conductance of FR4 printed substrate
Rate is only 0.36W/ (m.K), and thermal coefficient of expansion is 13～17ppm/K；Two is directly power VMOS tube to be directly installed on height
On heat conducting and heat radiating fin, externally dispelled the heat by the fin on fin or rib, it is clear that increase newly again in a motor body structure
The scheme being carried out the heat radiation of auxiliary power device by multiple fin is difficult to implement, this most existing brshless DC motor
Body and controller separate independent main cause.
It is in place of the novel creation of the present invention: devising the heat radiation topological structure of a kind of uniqueness, one is real easily

Heat conductivity.Power VMOS tube 7 is mounted on aluminum metal-matrix printed substrate 6, is the excellent of heat owing to supporting aluminum metal cylinder
Good conduction material, and support the cylindrical back side of aluminum metal and have the Archimedian screw shape vent rib 30 of protrusion, therefore, electricity
During the work of road, the heat that power VMOS tube 7 produces will not present concentration of local, and its hot-fluid will radially flow, and aluminum metal
Base printed substrate 6 screws in the inner thread 23 in motor bottom end cover 2 by its external screw thread 24 supported on aluminum metal cylinder,
And connect into an entirety, so that the high heat that power VMOS tube 7 produces can be emitted into outside quickly through motor bottom end cover 2,
On the other hand, owing to upper end cover 1 and bottom end cover 2 are to be connected to form an entirety by fixed screw, therefore there is high heat conduction system
