Square wave drives are primarily valued for their simple control algorithm, low cost, and high torque output, especially at low speeds and startup. Consequently, they are widely used in applications that are cost-sensitive and where ultra-smooth operation and low noise are not critical.
Key application areas include:
Home Appliances and Consumer Products
Fans / Circulators: Many household pedestal fans, indoor AC unit fans, and PC cooling fans use square wave drives for their cost-effectiveness.
Washing Machines: Used to drive the drum, especially direct-drive motors that require high starting torque.
