(1) The speed regulation offers excellent smoothness and high efficiency. At low speeds, the characteristic static shutdown rate is higher, providing better relative stability.
(2) Wide speed range with high precision.
(3) Low starting current, with no impact on the system or power grid, and significant energy-saving effects.
(4) The variable-frequency power supply is compact, making it easy to install, adjust, and maintain.
(5) Easy to automate the process.
(6) A variable frequency power supply and voltage stabilizer is required; currently, the cost is relatively high.
(7) During constant torque speed regulation, the overload capacity of the motor in the low-speed range is significantly reduced.
