Abstract
The utility model provides a bus-bar of a motor driver board, which comprises a printed circuit board (PCB) substrate. At least two power supply binding posts are arranged on the PCB substrate, and each power supply binding post is connected with a plurality of power tubes. The bus-bar of the motor driver board is small in volume and large in power carrying capacity. Due to the fact that the plurality of power tubes are connected to the same power supply binding post, electrical property parameters among phases of a power board are consistent mutually.
Description
Technical field
The utility model relates to a kind of motor-driven plate bus row.
Background technology
Existing polyphase machine drive plate bus row, each power tube connects a power-line terminal, thereby causes the unit for electrical property parameters of a plurality of power tubes on the motor-driven plate bus row inconsistent, and the phase current of motor is inconsistent, and power is little, reliability is low.
The utility model content
The utility model technical problem to be solved provides a kind of motor-driven plate bus row.
The technical scheme that the utility model solves the problems of the technologies described above is following: a kind of motor-driven plate bus row, and it comprises the PCB substrate, and said PCB substrate is provided with at least two power-line terminals, and each power-line terminal is connected with a plurality of power tubes.
Further, power-line terminal is 4 on the said PCB of the being arranged on substrate.
Further, be connected with 3 power tubes on said each power-line terminal.
The beneficial effect of the utility model is: the utility model motor-driven plate bus row's volume is little, and load power is big, because a plurality of power tubes are connected on the same power-line terminal, unit for electrical property parameters is consistent with each other between phase and phase thereby make power amplifier board.
Description of drawings
Fig. 1 is the utility model motor-driven plate bus row's a 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 motor-driven plate bus row, it comprises PCB substrate 1, and PCB substrate 1 is provided with 4 power-line terminals 2, and each power-line terminal 2 is connected with 3 power tubes.
The utility model motor-driven plate bus row, volume is little, load power is big, the power amplifier board phase and phase unit for electrical property parameters consistent with each other.
The above is merely the preferred embodiment of the utility model, and is in order to restriction the utility model, not all within the spirit and principle of the utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection range of the utility model.
Claims (3)
