Universal Motor
Definition and Functionality
The universal motor is a type of electric motor commonly used in vacuum cleaners. It is called “universal” because it can operate on either AC (alternating current) or DC (direct current) power sources. This makes it versatile and suitable for various applications.
The functionality of a universal motor relies on the interaction between a magnetic field and an electric current. It consists of a stator and a rotor. The stator contains the windings that generate the magnetic field, while the rotor, connected to the motor shaft, rotates inside the stator. When an electric current flows through the windings, it creates a magnetic field that interacts with the magnetic field of the rotor. This interaction causes the rotor to rotate.
In conclusion, the universal motor is a commonly used motor in vacuum cleaners due to its versatility and compact size. However, it is important to consider its noise, lower efficiency, and potential for wear and tear when evaluating its performance in vacuum cleaner applications.
Flow Through Motor
Explanation of Flow Through Motor
The flow through motor is another type of electric motor commonly used in vacuum cleaners. It is specifically designed for the purpose of generating suction and airflow in vacuum cleaners.
In a flow through motor, the motor and fan are combined into a single unit. The motor is positioned in the airflow path, allowing the air to pass through the motor and cool it as it operates. This design helps to prevent overheating and ensures the motor can maintain its performance over extended periods of use.
The flow through motor works by creating a pressure difference that generates the suction needed for vacuuming. As the motor spins, it creates a vacuum in the dust collection chamber, causing air and dirt to be drawn in through the cleaning head and into the vacuum cleaner.
In summary, the flow through motor is a popular choice for vacuum cleaners due to its efficient suction and longevity. While it may have some limitations in terms of airflow and cooling, regular maintenance can help optimize its performance and ensure a longer lifespan.
Peripheral Bypass Motor
Understanding Peripheral Bypass Motor
The peripheral bypass motor is another type of motor commonly found in vacuum cleaners. It is known for its efficiency and reliability. Unlike the universal motor, which can operate on both AC and DC power sources, the peripheral bypass motor is specifically designed for use with AC power.
The functionality of the peripheral bypass motor revolves around a different principle compared to the universal motor. It features a bypass mechanism that allows a portion of the air to bypass the motor, preventing it from overheating. This design ensures that the motor remains cool even during extended periods of use.
The peripheral bypass motor consists of a stator, rotor, and brushes. The stator houses the windings that generate the magnetic field, while the rotor rotates inside the stator. Brushes are used to create electrical connections to the windings. When an electrical current flows through the windings, a magnetic field is created, which interacts with the rotor’s magnetic field, resulting in its rotation.
In summary, the peripheral bypass motor offers efficiency, durability, and quiet operation, making it a suitable choice for vacuum cleaner applications. However, its limited versatility, size, and lower speed should be taken into consideration when evaluating its suitability for specific vacuum cleaner models.
Tangential Bypass Motor
Tangential Bypass Motor Explained
The tangential bypass motor is another type of motor commonly used in vacuum cleaners. Unlike the peripheral bypass motor, it is designed to work with both AC and DC power sources. This makes it more versatile and suitable for a wider range of vacuum cleaner applications.
The tangential bypass motor operates on a different principle compared to the peripheral bypass motor. It features a two-stage fan system that allows for greater suction power. The first stage of the fan creates a high-speed air flow which is then directed to the second stage of the fan, where it is further accelerated before exiting the motor. This design enhances the vacuum cleaner’s overall performance, especially in terms of suction power and debris pick-up efficiency.
Similar to the peripheral bypass motor, the tangential bypass motor also consists of a stator, rotor, and brushes. The stator contains the windings that generate the magnetic field, while the rotor rotates inside the stator. Brushes are used to create electrical connections to the windings. When an electrical current passes through the windings, a magnetic field is created, which interacts with the rotor’s magnetic field, resulting in its rotation.
In conclusion, the tangential bypass motor offers versatility, high suction power, and compact design, making it a suitable choice for vacuum cleaner applications. However, its noise level, cost, and maintenance requirements should be taken into consideration when selecting a vacuum cleaner model.
