Abstract

The invention provides a motor drive board busbar which comprises a printed circuit board (PCB) substrate. The PCB substrate is provided with at least two power source binding posts. Each power source binding post is connected with a plurality of power tubes. The motor drive board busbar is small in size and large in load bearing power. Due to the fact that the plurality of power tubes are connected with the same power source binding post, electrical property parameters of a phase of a power board is in accordance with electrical property parameters of another phase of the power board.

Description

technical field [0001] The invention relates to a motor drive board bus bar. Background technique [0002] In the existing multi-phase motor drive board bus bar, each power tube is connected to a power terminal, which leads to inconsistent electrical performance parameters of multiple power tubes on the motor drive board bus bar, inconsistent phase current of the motor, low power and reliability Sex is low. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a motor drive board bus bar. [0004] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: a bus bar of a motor drive board, which includes a PCB substrate, on which at least two power terminals are arranged, and each power terminal is connected to a plurality of power tubes. [0005] Further, there are 4 power terminals arranged on the PCB substrate. [0006] Further, 3 power tubes are connected to eac...
