Title: SERVO MOTOR, SERVO MOTOR SYSTEM, AND POWER SUPPLY METHOD
Abstract:
A servo motor according to the present invention comprises a first body and a second body that are configured to be rotatable relative to each other. The second body comprises two first electrodes in which communication information is modulated according to a pulse period and two voltages opposite in phases to each other are applied as a PWM power supply, and the first body comprises a motor, a first control circuit that generates a direct current voltage from the two voltages respectively supplied through the two first electrodes of the second body and that extracts the communication information, and two second electrodes that are individually conductively connected to the two first electrodes of the second body.
