The working principle of the static phase advancer is based on advanced control technology that enhances motor performance by optimizing the electrical characteristics in real time. When the motor is running, the static phase advancer is connected in series within the motor circuit to monitor and process the rotor current and synchronous voltage signals. These signals are analyzed by a microprocessor, which then triggers a thyristor to generate an appropriate control signal. This thyristor-based AC-AC converter takes the standard power frequency input and transforms it into a power source with the same frequency as the rotor current. This converted power is then fed back into the rotor circuit, altering the phase relationship between the rotor current and voltage. By adjusting this phase relationship, the magnetic field interaction between the stator and rotor changes, leading to a more favorable phase alignment between the stator current and voltage. This results in a reduced power factor angle, improving the overall power factor of the motor. As a consequence, the stator current decreases, which lowers the copper losses and temperature rise within the motor. This not only increases the motor's efficiency but also improves its overload capacity and overall operational stability. In simpler terms, the static phase advancer enables the motor to behave similarly to a synchronous motor—without actually operating at synchronous speed. It creates a "pseudo-synchronous" or "sub-synchronous" state, allowing the motor to achieve a higher power factor, similar to that of a true synchronous motor. Since synchronous motors typically have a power factor close to 1, this improvement leads to significant energy savings compared to traditional asynchronous motors. By reducing the reactive component of the current, the motor draws less total current, further enhancing its efficiency and performance under various load conditions.
