1.Integrated design of metal support, motor drive/ deceleration
Gear counters use all-metal support to achieve high strength structure, no easy to deform. The character wheels are placed in the middle of support, which effectively cuts external magnetic field interference with the help of shielding ability of metal plate. More diamagnetic ability, Better performance. 
2.Stepper motor drive mechanism
Use the integrated design of the reducer and the motor to integrate motor and gear connection without the intermediate procedure of screws installation, which guarantees the synchronous operation of each drive and deceleration mechanism and achieves the direct connection between motor drive gear and reducer gear. Less motor power loss, developed drive capacity, no shut-down.

Electronic Watt-hour Meter Stepping Counter is mainly used as the power display instrument in static watt-hour meter, which adopts low power consumption stepper motor driving drum to realize the counting function. This design greatly reduces the manufacture cost of watt-hour meter without the requirement of memory chips. The products can be used in countries and regions where the temperature is over 20 degrees Celsius below freezing. It has the ability to measure without the influence of cold which is the disadvantage of LCD.
