Problems solved by technology

Each drive control card 130 is connected to the power supply module 110 through the power supply line 111 respectively, and the start signal of each drive control card 130 also needs to be connected in parallel with the signal line 121, and then connected to the control module 120, each drive control card control each other independently, resulting in too much wiring of the power line 111 and signal line 121, which not only takes up space, but also costs a lot

Abstract

The motor driving device is used for driving a plurality of motors and comprises a packaging shell, a power card and a plurality of driving control cards, the power card and the driving control cards are located in the packaging shell, the power card integrates a plurality of power signals and a plurality of control signals, and the driving control cards are controlled through a group of communication lines. According to the motor driving device, the plurality of driving control cards are connected in parallel on the power supply card, power supply connection and signal connection are realized through the power supply card, the power supply card converts signals of the control module into signals which can be identified by the driving control cards, and the plurality of driving control cards can be controlled by one group of communication lines.

Description

technical field [0001] The present invention relates to motor drive technology, more specifically, to a multi-channel integrated motor drive device. Background technique [0002] The balance wheel sorter is one of the necessary facilities for advanced distribution centers, and it is also an indispensable part of large logistics centers. The balance wheel sorter has high sorting efficiency and has become a key factor in improving the efficiency of logistics distribution . [0003] At present, the balance wheel sorter uses a plurality of brushless motors to drive a corresponding number of power balance wheels to achieve steering and transmission. A balance wheel sorter has about 30, 50 and 100 brushless motors, and each drive control card can drive 4 to 6 brushless motors, so the motor drive device includes multiple drive control cards. A plurality of drive control cards are respectively fixed under the motors driven by them, which takes up a lot of space. Each drive contro...
