The motor accepts 7–13 V DC and accepts a PWM signal between 10 and 60 kHz, with 5 V defined as high and 0.4 V as low. That makes it compatible with most appliance main boards without extra level shifting.
Locked-rotor and reverse-polarity protection prevent field failures caused by a stalled impeller or a miswired connector. A sealed cover option raises durability in dusty or humid installations. The 165 × 66 mm impeller format is a typical match.
