stepper counter
Stepper motor counter is mainly used for static electronic watt-hour meter as a power display instrument. It uses low power stepper motor to drive the drum wheel, so as to realize the function of counting. This design greatly reduces the design cost of electronic electricity meters, no need to store the memory of the chip, in the low temperature more than -20℃ above the country and region use, has not affected by the cold metering, which is LCD cannot achieve the advantage.
