With PWM control the effective coil current with constant voltage supply is set via the duty cycle of
the rectangular signal. The PWM frequency is harmonized here on the one hａnd with its resonance
frequency and the damping of the spring-plunger-system, and on the other hａnd with the magnetic

circuit’s inductance. If the duty cycle t1/T (t1: power-on time, T: cycle duration, f=1/T: frequency) increases,
the effective coil current “I” also increases, because the rectangular signal has also increased.
If, however, the duty cycle falls, the effective coil current also falls.
Generally speaking: Small coils (e. g., type 2871) with low magnetic force react sensitively to higher
frequencies. With low frequencies these generate high motion amplitudes and an unnecessarily
high noise level. Big coils with a high magnetic force (e. g., type 2875), however, only result in dither
movements, and therefore sliding friction with low frequencies.
