Title:
SERVO MOTOR, CONTROL METHOD FOR SAME, AND SERVO DRIVER
Document Type and Number:
WIPO Patent Application WO/2024/065783
Kind Code:
A1
Abstract:
A control method for a servo motor includes: in a process of pre-charging the bus capacitor, in a case that a voltage of the bus capacitor is less than a predetermined first voltage value, releasing the short circuit between the two terminals of the pre-charge resistor, and establishing a short circuit between at least two phases of the AC power output terminal of the inverter unit; and in the process of pre-charging the bus capacitor, in a case that the voltage of the bus capacitor is greater than the predetermined first voltage value, short-circuiting the two terminals of the pre-charge resistor, and releasing a short circuit between any two phases of the AC power output terminal of the inverter unit. The control method is conducive to lowering costs in additionally configuring a braking function. A servo driver and a servo motor are also disclosed.
