6.2
Insufficient magnetic signal of the speed sensor
When the speed sensor signal is stronger, it can resist the external pulses, the speed sensor can measure
the outputted signal which is more than 3 Volts. When the voltage is less than 3 Volts, You shall reduce
the gap between the magnetic speed sensor and the ring gear teeth, which can improve the amplitude of
the signal. The gap shall less than 0.45mm. If the voltage is still less than 3 Volts, You shall check the
whether the magnetism of the speed actuator is too weak.
6.3
Electromagnetic interference (EMI)
The electronic governor system can be adversely affected by large interfering signals that are introduced
through the cabling or through direct radiation into the control circuits. To avoid the medium interference,
the speed governor includes the filter unit and shielding designs that can protect the sensitive circuits from
the external interference.
It is difficult to predict the value of the interference. You shall consider all the possible range of the
interference such as the radio communications of the space field, wireless walkie-talkie, and wireless radio
transmitter and also including the use of magneto, solid-state ignition systems, and voltage adjuster or
battery chargers.
When You think that space field or other systems will affect the speed governor system operation by
conduction or direct radiation during the using period, we suggest that You shall use the double shielded
cables as the external cables of the governor. Also ensure that one terminal of the shielded cable which
includes the 360 degree of the speed actuator shall connect to the shell of the governor.
And mount the speed Governor on a grounded metal back plate or place it in a sealed metal box to avoid
the electronic interference. There will be a good effect when using the metal cover or the metal container.
The most common anti-interference measure is to use the shielding wire. If using the generator with brush,
You
can’t ignore the electronic spark interference, so You shall use the special shielding measure to the
huge interference environment. If You
can’t solve this kind of problems, please contact with our engineers.
They will give You some more suggestions.
