In industrial applications, why are single-phase motors often preferred?

Single-phase motors are often preferred in industrial applications primarily due to their simplicity and cost-effectiveness. These types of motors are generally easier to install and maintain compared to more complex motor types, such as three-phase motors. Their straightforward design allows for lower production costs and, consequently, reduced prices for end-users, making them an attractive option for a variety of applications.

Moreover, single-phase motors are suitable for smaller loads and are commonly used in scenarios where the power requirements do not necessitate the additional capabilities of three-phase motors. Since many small industrial machines and appliances operate on single-phase power, they can be efficiently powered by these motors without the need for extensive electrical infrastructure modifications. This combination of simplicity and affordability makes single-phase motors a practical choice for various industrial uses where budget constraints and ease of installation are important factors.
