Hand-held vacuum cleaners, also known as handheld or portable vacuums, typically use one of the following types of motors:
Brushed DC Motors: Brushed DC motors are the most common type of motor used in hand-held vacuum cleaners. They are simple, affordable, and offer sufficient power for most handheld vacuum applications. These motors use brushes and a commutator to transfer electrical power to the motor's armature, which creates the rotational motion needed for suction.
Brushless DC Motors (BLDC): In recent years, many high-end hand-held vacuum cleaners have started incorporating brushless DC motors. BLDC motors are more efficient and durable than brushed motors because they eliminate the need for brushes, which reduces friction and wear. They are often lighter, provide more consistent power, and have longer lifespans, making them an attractive option for premium handheld vacuums.
AC Motors: Some older or cheaper hand-held vacuum models may use basic AC (alternating current) motors. AC motors are less common in modern handheld vacuums due to their bulkier design and limited efficiency compared to DC motors.
The choice of motor depends on factors such as cost, performance requirements, and the overall design and features of the hand-held vacuum cleaner. Brushed DC motors are still prevalent in many budget-friendly handheld vacuums, while brushless DC motors are becoming more popular in high-performance and premium models. The trend is moving towards brushless technology, as it offers numerous advantages over traditional brushed motors.
