It is understood that law enforcement officers have investigated and dealt with uncertified production and production licenses that have expired and have not been renewed, as well as companies that violate regulations and exceed the scope of production. For dealers to cater to the demand of some consumers for speed, they deliberately remove the speed-limiting devices and urge them to make timely corrections.
According to law enforcement officials, the national standard “General Technical Conditions for Electric Bicycles†requires that the maximum speed of electric bicycles should not exceed 20Km and the rated output power should not exceed 240W. The weight of the vehicle should not exceed 40Kg, and the braking performance should not exceed 4 meters. It must be good. The pedaling function, etc., is a national mandatory standard. If the electric vehicle exceeds the limit, it will bring greater safety risks to pedestrian safety.
Low iron loss, which is the most important indicator of the quality of silicon steel sheets. In a strong magnetic field, the magnetic induction intensity (magnetic induction) is high, which reduces the volume and weight of the iron core of the motor and the transformer, and saves silicon steel sheets, copper wires and insulating materials. Moreover, the surface is smooth, flat and uniform in thickness, which can improve the filling factor of the iron core. Good punchability is more important for the manufacture of micro and small motors.
The surface insulating film has good adhesion and weldability, and can prevent corrosion and improve punchability.
Recently, the law enforcement officers of the Inspection Bureau of the Bureau of Quality Supervision of Zaozhuang City conducted a major inspection of the electric vehicle enterprises in Zaozhuang City.
