Common Types of Motors Used in Electric Vacuum Cleaners

Electric vacuum cleaners typically use the following types of motors:

1. Brushed Dc Motor:

    Characteristics: Brushed DC motors are traditional motors widely used due to their low cost and simple control.

    Advantages: Easy to control, low cost.

    Disadvantages: Noisy, relatively low efficiency, requires regular maintenance (brush replacement).

    Use Case: Mainly used in midtolowend vacuum cleaners or products where cost is a critical factor.

2. Brushless DC Motor (BLDC):

    Characteristics: Brushless DC motors have become increasingly popular in electric vacuum cleaners in recent years due to their high efficiency, long lifespan, and low noise.

    Advantages: High efficiency, low noise, long lifespan, maintenancefree.

    Disadvantages: Higher cost, complex control, requires a specialized electronic controller.

    Use Case: Widely used in highend vacuum cleaners, especially handheld and cordless models.

3. Universal Motor:

    Characteristics: These motors can operate on both AC and DC power sources and have high speed and power.

    Advantages: Moderate cost, powerful, easy to control.

    Disadvantages: Noisy, lower efficiency.

    Use Case: Commonly used in traditional corded vacuum cleaners.

Examples of Specific Motor Models:

  Shunli Planetary Gear Brushless DC Motor (Model:GMP36): A brushless DC motor commonly used in highend handheld vacuum cleaners, characterized by high speed (up to 100,000 RPM), high efficiency, and low noise.

  Shunli RS550 Brushed Motor: A brushed DC motor widely used in midtolowend vacuum cleaners, providing moderate power and cost efficiency.

Choosing the right type and model of motor requires weighing factors such as the vacuum cleaner’s design requirements, target market, and cost control. Brushless DC motors are typically the preferred choice for modern highend vacuum cleaners, while brushed motors and universal motors continue to play roles in more traditional and costsensitive designs.
