Abstract
Official abstract text for this publication.
A multi-shaft motor drive device comprises at least one amplifier module, a control substrate, and a power substrate. The at least one amplifier module is configured to supply power to at least one motor. The control substrate connected with the amplifier module. The power substrate is connected with the amplifier module. The amplifier module comprises a switching element. The control substrate is provided with a signal line disposed for controlling the switching element according to a motor control instruction from a master controller. The power substrate is provided with a power line disposed for supplying power to the amplifier module. The control substrate and the power substrate are arranged separately each other.
