Embodiment
[0018] Embodiment: This application provides a multi-axis motor driver power supply circuit, such as figure 1 As shown, the multi-axis motor driver power supply may include: one main switching power supply module and at least two secondary switching power supply modules; the output of the main switching power supply module is used as the input of each secondary switching power supply module; The number is equal to the number of axes of the multi-axis motor.
[0019] The main switching power supply module is used to supply power to the general function part of the multi-axis motor driver, and each secondary switching power supply module is used to supply power to a corresponding inverter IGBT drive module in the multi-axis motor driver.
[0020] Optionally, the general function part includes at least one of a fan module, an external IO module, and various drive control modules.
[0021] In the multi-axis motor driver, usually the multi-axis common multi-axis drive control modu...
