EC Motor/fan overview
EC Motor/Fan When you selected the EJ Air Purifier you chose the latest and
best German engineered motor available. EC (Electrically Commutated) motors
use electronics to convert the AC voltage to DC to run the motor.
EC Advantages
Why does the motor/fan start and stop more slowly than an AC motor? EC
motors have a soft start programmed into the motor to limit the start-up
current the motor draws.The ramp down after power is removed is only a
function of the inertia of the fan and the friction of the bearing system. A high
quality bearing system will take longer to slow down and stop since the friction
is minimized (alignment is better, lubricant is better, etc.).
