Motor applications for car air purifiers

Car air purifiers use micro-motors to drive fan impellers at speeds of 800–3000 RPM, generating airflow that circulates the interior air 5–8 times per hour.

Why is there such a significant price gap in the car air purifier category? The key lies in the type of motor selected.

Models powered by brushed motors offer the advantage of low cost, typically ranging from $0.40 to $1.40 (3–10 RMB). However, they suffer from a short lifespan of around 500 hours and high noise levels between 60–75 dB. Consequently, air purifiers using brushed motors are generally priced under $11 (80 RMB), with most falling in the $4–7 (30–50 RMB) range.

Recommended models include the 310, 330, and 36ZY DC brushed motors.

Models powered by brushless motors offer significant advantages, including a lifespan exceeding 10,000 hours, noise levels below 45 dB, and over 30% greater energy efficiency compared to brushed motors. The downside is a higher component cost, typically ranging from $4 to $7 (30–50 RMB). As a result, air purifiers built with brushless motors generally retail for over $21 (150 RMB).

Recommended models include the 3025 and 3523 external rotor brushless motors, both of which are ideal for compact air purifier designs.
