Vacuum Motor Specs & Selection

BLDC series

BLDC high-speed fan motors

Three voltage taps on one platform with identical envelope, so a model change does not need a new housing. No brushes means no wear and no sparking.

Model	Voltage (V)	Power (W)	Suction (W)	Vacuum (kPa)	Noise	Insulation
BLDC-65G	14.4 / 18 / 21.6	120 / 160 / 240	50 / 65 / 85	17 / 20 / 25	< 100 dB(A)	Class E
BLDC-85G	14.4 / 18 / 21.6	120 / 160 / 240	50 / 65 / 85	15 / 19 / 25	< 100 dB(A)	Class E

Values correspond to the 14.4 V / 18 V / 21.6 V taps respectively.

Three power taps, one envelope — no housing change when switching models.
High suction-to-weight ratio: 85 W suction at 240 W input.
Balanced rotor and preloaded bearing for low vibration and long life.
Shaft, flange, impeller diameter, lead wire and connector built to your drawing.

AC series

One platform covers 100–120 V and 220–240 V markets. PT for maximum vacuum, PA for maximum airflow (wet & dry, industrial), PE for household value.

Model	Voltage	Frequency	Power (W)	Vacuum (kPa)	Airflow (L/s)	Insulation
V1J-PT	100–240 V	50/60 Hz	600–1400	17–28	35–40	Class E / F
V1J-PA	100–240 V	50/60 Hz	600–1400	17–25	36–50	Class E / F
V1J-PE	100–240 V	50/60 Hz	600–1400	17–25	32–41	Class E / F
V3J-P	100–240 V	50/60 Hz	550–900	14–22	29–36	Class E / F

Wide-voltage design: one platform for 100–120 V and 220–240 V.
Class E/F insulation, double-impregnated stator for humid and dusty duty.
Brush life matched to 500–1000 h; brush holder is serviceable.
Optional thermal protector, EMI suppression (choke / X2 capacitor) and earth tab.

Selection

Start from your machine type, then map to a model — three steps to an answer.

Your product	Recommended	Why
Cordless stick / handheld	BLDC-65G（18V / 21.6V）	Highest suction per gram; 85 W at 240 W input
Entry cordless / lightweight	BLDC-85G（14.4V）	Lower cost, 15–25 kPa for short cleaning
Robot vacuum / mite remover	BLDC-65G（14.4V）	Compact, low voltage, long life
Corded canister / upright	V1J-PT	Maximum vacuum (up to 28 kPa) for deep carpet
Wet & dry / industrial	V1J-PA	Maximum airflow (up to 50 L/s)
Household canister / cost-driven	V1J-PE	Balanced vacuum and airflow at lower cost
Floor washer / scrubber	V3J-P	550–900 W, compact, stable water pick-up

Target vacuum (kPa), airflow (L/s), input power and battery voltage — that is all we need.
