A Frequency generator for generating a working frequency for a transmission signal of a rail contact of an axle counter, the frequency generator comprising:• a series resonant circuit comprising a transmitter coil unit (800) of the rail contact and a capacitor (600),is characterized in that the frequency generator further comprises• an inverter (400), the output of which is connected to the capacitor (600), wherein the inverter is configured to generate an oscillating voltage and to feed the generated oscillating voltage to the transmitter coil unit (800) of the rail contact via the capacitor,• a current transformer (300) for synchronizing the output voltage of the inverter to the current in the series resonant circuit (600, 800),• a start-up circuit (200) electrically connected to the inverter and configured to trigger the inverter (400) and configured to be electrically connected to an input power supply.The inventive frequency generator comprises a robust and effective circuit for generation of magnetic fields.Manufacturing effort and expensive components can be reduced.
