Verfahren zum Ansteuern eines Elektromotors einer Dosierpumpe

摘要

The invention relates to a method for controlling the electric motor of a metering pump, wherein the amount of fluid (Vsoll) to be delivered is determined by an external impulse generator, every impulse (t) being associated with a predetermined amount of fluid (Vsoll). The control detects the interval ( DELTA t) of the two impulses (t) received last and controls the electric motor in such a manner that the amount of fluid to be delivered is evenly distributed across the subsequent impulse interval based on the interval previously detected.
