Angle bisecting hall position, according to the 120 ° of position relationships to change magnetic pole logarithm and Hall in current potential angle.And motor in the present invention
Winding be the dual connection of line star triangle of three-phase six, it is necessary to draw six roots of sensation phase line, method for winding is also three to alternate positive and negative coiling；Suddenly
That line is by original five line（Red-black yellowish green indigo plant）It is changed to eight lines（Red-black yellowish green indigo plant（It is yellowish-white）（It is green white）（Lan Bai））；This is using logical
With being realized with Hall direction selecting controller, in Hall angle this part, due to Hall used in triangle and wye connection
Angle is differed, so the number of built-in Hall sensors is 6.No Hall direction selecting controller can also be used in addition real
Existing, this implementation method need to only connect five lines.3 Halls are only needed with without Hall direction selecting controller.
Realize that steady switch motor operational mode must find a triangle and star-like equalization point, this equalization point
Exactly switch when the rotating speed of triangle is consistent with star-like rotating speed, to realize that this function needs to set in the inside of control module 2
A Hall Rotating speed measring feedback signal is put, when both of which rotating speed reaches consistent, switching state.This pattern is that basis turns
The trend of speed judges, that is to say, that when motor speed declines from high speed, is exactly that triangle switching is star-like, works as motor speed
It is exactly star-like switching triangle when being lifted from low speed.All in all：Non-brush permanent-magnet DC motor M begins to use star-like from startup
Connection, when rotating speed reaches speed-changing, non-brush permanent-magnet DC motor M is switched to triangle pattern, when climbing, motor speed
When dropping to speed-changing, non-brush permanent-magnet DC motor M switches to Star Schema.This set of overall implementation is just sharp well
With wye connection high pulling torque low speed characteristics and the high rpm low torque characteristic of delta connection, and in the mistake run at high speed
Cheng Zhong, the power ratio wye connection of delta connection consumption is low by 40%, and during low speed is climbed, the moment of torsion of wye connection is again
50% can be improved.So, the set motor running mode will greatly promote the course continuation mileage and load-carrying climbing capacity of motor, with
It is lower that each stage is described in detail respectively：
Startup stage
After circuit is connected, motor handle is turned, control module 2 obtains an enabled instruction, control non-brush permanent-magnet DC motor M
Run according to six step ripple modes, at this moment pattern switching relay KC terminal voltages are 0V, the first relay KM1 obtains electric work, second
Relay KM2 must not electricity be stopped, finally according to the situation of three relays conducting, obtain non-brush permanent-magnet DC motor three-phase
Line A1B1C1 is directly output to the ABC ends of control module 2, the A2B2C2 connections of non-brush permanent-magnet DC motor triple line, motor Hall
Signal is output to the red-black yellowish green blue end of control module 2 by red-black yellowish green blue line, yellowish-white, green white, blue white hanging, DC without
Brush motor M is run according to Star Schema, needs to overcome the deadweight of electric car in itself under the state, so generally torque demand is high,
Speed demand is low.
The high-speed transitions stage：
Non-brush permanent-magnet DC motor M is converted to high speed stage from low speed, and handle is still in the state turned, and control module 2 is just
Often work, when control module 2 receives a tach signal（48V800w motors speed-changing is 1200-1800rpm）, pattern
It is 12V, KC work, due to KC work, then the first relay KM1 is powered off, the second relay KM2 to switch relay KC terminal voltages
It is powered, situation about being turned on according to three relays obtains motor triple line A1-C2, B1-A2, C1-B2 and is output as ABC ends, motor
Hall signal by the red-black yellowish-white green white blue white red-black yellowish green blue end for being output to control module 2, it is yellowish green it is blue vacantly, DC without
Brush motor M is run according to triangle pattern.In the stage after motor starting, due to the effect of inertia, what electric car needed
Moment of torsion is less and less, and speed is more and more faster.When the efficiency and power output of motor reach cutting for wye connection and delta connection
When changing, control module switch motor running status allows motor speed to be lifted, and moment of torsion declines.
Climb the conversion stage：
Non-brush permanent-magnet DC motor M is in the stage of climbing, and because load is increased, motor speed declines, when permanent-magnet DC brushless electricity
When machine M rotating speeds drop to pattern switching rotating speed（48V800W motors speed-changing is 1200-1800rpm）, at this moment pattern switching after
Electrical equipment KC terminal voltages are 0V, and the first relay KM1 obtains electric work, the second relay KM2 must not electricity be stopped, finally according to three
The situation of individual relay conducting, obtains the ABC ends that motor triple line A1B1C1 is directly output to control module 2, motor triple line
A2B2C2 connections, motor hall signal is output to the red-black yellowish green blue end of control module 2 by red-black yellowish green indigo plant, yellowish-white, green white, blue
White hanging, non-brush permanent-magnet DC motor M is run according to Star Schema.During climbing, due to the gradient, make permanent magnetism
DC brushless motor M will not only overcome the power that moves forward to also have a radial component.The reaction of control module 2 is reduction rotating speed,
Increase moment of torsion.At this moment non-brush permanent-magnet DC motor M is in delta connection, and the characteristic possessed is high speed low torque state,
So when rotating speed reaches certain amount, switching working mode changes into wye connection from delta connection, big to reach
The environment of torque output.
Stop phase：
When non-brush permanent-magnet DC motor M needs to shut down, handle resets, and control module 2 obtains a halt instruction, pattern
It is 0V to switch relay KC terminal voltages, and the first relay KM1 obtains electric, and the second relay KM2 must not electricity, non-brush permanent-magnet DC motor
M motor status return to star-like connection status.
The present invention is on the basis of first embodiment, it is further provided the of a kind of non-brush permanent-magnet DC motor control method
Two embodiments, it comprises the following steps：
S1：When non-brush permanent-magnet DC motor rotating speed is less than 1800rpm, perform star-like mode of operation, now triple line then with forever
The formation Y-connection of magnetic DC brushless motor；Or
S2：When the non-brush permanent-magnet DC motor rotating speed is greater than or equal to 1800rpm, triangular form mode of operation is performed, now
Triple line is then connected with non-brush permanent-magnet DC motor formation triangle.
Wherein the switching of mode of operation is realized by least three relays, and its repeat circuit includes pattern switching relay
Device, the first relay being connected with pattern switching relay and be connected with pattern switching relay and with the first relay
The second relay that device is connected in parallel, wherein the normally opened contact of the first relay or the second relay is disposed therein one group of three-phase
On line, and the normally opened or normally-closed contact of pattern switching relay is arranged on the Hall line being connected with Hall sensor.
Because the present invention uses above-mentioned technical proposal, with advantages below：
50% torque output can be lifted on the motor of same power without influenceing high speed characteristics, be refer to shown in Fig. 5-6, and not
Increase cost.That is；28-30N.m torque output can be made on 48V800W motor, eventually through gear-box
280N.m or so can be exported after deceleration, 100N.m is improved than common electric machine fully.
