Description
Technical field
The utility model is related to motor driven systems field, more particularly to DC brushless motor and permagnetic synchronous motor can
The improvement of the drive system of speed governing.
Background technology
At present, DC brushless motor and permagnetic synchronous motor be because efficiency high, energy consumption is low and is widely used, but due to
DC brushless motor and permagnetic synchronous motor and traditional common electric machine are very big existing for speed regulative mode and the mode of connection
Difference, specifically：First, traditional common electric machine the mode of connection as shown in figure 3, motor by selecting switch connect power supply,
So as to when connecting different windings so that motor obtains different rotating speeds；2nd, DC brushless motor and permagnetic synchronous motor connect
Line mode is as shown in figure 4, speed adjustment module is connected in the drive module of motor by it, so as to pass through pwm signal or voltage
Signal is adjusted to change the rotating speed of motor.Therefore, common multi gear is directly substituted in DC brushless motor and permagnetic synchronous motor
The application of position rotating speed motor above brings great inconvenience.
The content of the invention
The utility model is directed to problem above, it is proposed that a kind of delicate structure, easy to use and stability are good, can not change
On the premise of becoming original mode of connection, being used for for traditional common electric machine is directly replaced with DC brushless motor and permagnetic synchronous motor
The speed-adjusting driving system of DC brushless motor and permagnetic synchronous motor.
The technical solution of the utility model is：The DC brushless motor connects selecting switch by speed-adjusting driving system,
The selecting switch connects with power supply；
If the selecting switch has dry separation contact；
The speed-adjusting driving system includes microprocessor, selection speed monitoring unit and driver element, some selections
Contact is both connected on the selection speed monitoring unit, and the selection speed monitoring unit, driver element are both connected to micro- place
Manage on device, the driver element is also connected with DC brushless motor.
The microprocessor is used to receive and handle the incoming signal of selection speed monitoring unit and for controlling driving single
Member.
The driver element is used to control DC brushless motor to rotate.
During the utility model use, when disconnecting link connection is in a certain select on contact, then the corresponding of motor is corresponded to
Speed, i.e., as the speed regulative mode and the mode of connection of traditional common electric machine, final electricity is regulated and controled by selecting switch
Machine rotating speed.So that be connected with this case the DC brushless motor of speed-adjusting driving system and permagnetic synchronous motor can not change it is original
On the premise of the mode of connection, directly replaced with traditional common electric machine.
The utility model has detection function in the input of connection selecting switch, it can be determined that whether the input connects
Energization source, if so, the rotating speed motor that drive circuit can be set according to the input, so as to be connected not by selecting switch
Same input finally realizes speed-regulating function to obtain different motor speeds.Client can set increase according to being actually needed
Or reduce rotary speed gear number.In addition, when DC brushless motor, operation, circuit are not disconnected, without quiescent dissipation.
The utility model has the characteristics of cost is low, using effect is good, stability is good, has wide range of applications on the whole.
Brief description of the drawings
Fig. 1 is the structural representation of this case,
Fig. 2 is the internal structure schematic diagram of this case,
Fig. 3 is the background technology schematic diagram one of this case；
Fig. 4 is the background technology schematic diagram two of this case.
Embodiment
The utility model as Figure 1-4, by taking DC brushless motor as an example, does representative elaboration：
The DC brushless motor connects selecting switch by speed-adjusting driving system, and the selecting switch connects with power supply；
If the selecting switch has dry separation contact；
The speed-adjusting driving system includes microprocessor, selection speed monitoring unit and driver element, some selections
Contact is both connected on the selection speed monitoring unit, and the selection speed monitoring unit, driver element are both connected to micro- place
Manage on device, the microprocessor is used to receive and handle the incoming signal of selection speed monitoring unit and for controlling driving single
Member, the driver element is also connected with DC brushless motor, for controlling DC brushless motor to rotate.So, when disconnecting link connects
Lead to when on a certain selection contact, select speed monitoring unit directly will transmit into microprocessor, and by microprocessor
Processing, conversion after transmit to driver element so that driver element controlled motor rotate.So as to be connected whenever disconnecting link in a certain choosing
When selecting on contact, then the corresponding speed of motor, i.e. speed regulative mode and the mode of connection one with traditional common electric machine are corresponded to
Sample, final motor speed is regulated and controled by selecting switch.So that it is connected with the DC brushless motor of speed-adjusting driving system in this case
And permagnetic synchronous motor can directly be replaced on the premise of original mode of connection is not changed with traditional common electric machine.
