Verfahren zur Ermittlung der Födermenge einer Sekundärlufteinblasung
摘要
The speed of the electric motor is measured by a simple voltage measurement without use of any additional measurement sensors. The effective voltage applied to the motor rotor may be controlled by chopping the supply voltage into pulses of variable width. The back EMF of the motor is measured during the OFF period of the pulses.
