Abstract
A power plate of a polyphase motor power driving controller includes a PCB substrate; the PCB substrate is provided with a power supply terminal and a plurality of power tubes; the power tubes are connected with the power supply terminal; and the power tubes are distributed uniformly around the power supply terminal with the power supply terminal as the center. The power plate of a polyphase motor power driving controller is advantageous in that the power tubes are distributed uniformly, thereby the novel power plate provided in the utility model possesses a small volume, the bearing power is large, and the consistency of the phase-to-phase electrical property parameters of the power plate is good.
Description
Technical field
The utility model relates to a kind of polyphase machine power driving controller.
Background technology
Existing polyphase machine power driving controller power amplifier board, power tube adopts in line mode to be connected on the power-line terminal, makes the unit for electrical property parameters of the power tube on the power amplifier board inconsistent, makes the phase current of motor inconsistent, and power is little, reliability is low.
The utility model content
The utility model technical problem to be solved provides a kind of polyphase machine power driving controller power amplifier board.
The technical scheme that the utility model solves the problems of the technologies described above is following: a kind of polyphase machine power driving controller power amplifier board; It comprises the PCB substrate; Said PCB substrate is provided with a plurality of power tubes and power-line terminal; Said power tube is connected with power-line terminal, power tube with the power-line terminal be the center be evenly distributed on power-line terminal around.
Further, power-line terminal is 6.
Further, 6 power-line terminals are divided into two lines and are symmetricly set on the PCB substrate.
The beneficial effect of the utility model is: the equally distributed structure of a plurality of power tubes, and make the volume of the utility model power amplifier board little, load power is big, and power amplifier board unit for electrical property parameters between phase and phase is consistent with each other.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing the principle and the characteristic of the utility model are described, institute gives an actual example and only is used to explain the utility model, is not the scope that is used to limit the utility model.
As shown in Figure 1; A kind of polyphase machine power driving controller power amplifier board; It comprises PCB substrate 3; Said PCB substrate 3 is provided with a plurality of power tubes 1 and power-line terminal 2, and said power tube 1 is connected with power-line terminal 2, said a plurality of power tubes 1 with power-line terminal 2 be the center be evenly distributed on power-line terminal 2 around.
Power-line terminal 2 is 6, is evenly distributed with a plurality of power tubes 1 on said each power-line terminal 2.
6 power-line terminals 2 are divided into two lines and are symmetricly set on the PCB substrate 3.
