The technical performance of motor refers to the characteristic parameters and working characteristics of electrical and mechanical(6354 brushless motor). Safety certification organization is a third-party organization independent of both the supplier and the demander, which confirms that the product conforms to safety standards or specifications and gives approval procedures (including safety signs)(sliding gloves for skateboarding).

The international electronic Committee stipulates that the security certification bodies of Member States shall implement the security certification system(electric skateboard esc). The safety certification system is implemented by the relevant standards authorities of member countries or their authorized agencies, such as CCEE, UL, CSA, jet or JMI, VDE Committee of Germany, etc(esc for skateboard). Its purpose is to guide users to select safety products by means of safety certification mark.
Therefore, it is widely used in precision servo control system and high-performance drive system which require good dynamic performance(6374 sensored motor). The allowable impulse current is 3-5 times of the rated current. The rated operating state value of motor is called rated value(electric skateboard vesc). The portable or movable storage battery and dry battery are used as the power supply for light and convenient operation.
Compared with the asynchronous motor, the DC motor with the same power and speed has the advantages of small size and high efficiency, but the disadvantages are more consumables and complex technology(6374 170kv). However, the speed range of DC motor is adjustable from hundreds to tens of thousands of revolutions per minute, while the speed of asynchronous motor is limited by frequency (50Hz), and its speed is not more than 3000r / min(5065 200kv).
It has good starting performance and overload performance, and can withstand frequent impact, braking and reversal(dual 6374 190kv). The combination of DC motor and gear reducer has developed into a new category of "gear motor". PWM PWM governor or SCR governor is used for stepless speed regulation, which can achieve the purpose of low speed and large torque(5065 brushless motor). The products have a large number of demands in various industries.
With the breakthrough of DC motor design theory(6384 brushless motor), calculation method and manufacturing technology, the development of power electronic control technology and the growing maturity of components, DC motor and its matching controller can be developed to the direction of high power (high torque, high speed), high efficiency and light weight(dual 6354 motor), with high performance price ratio and torque quality ratio.
The rated data and common terms of DC motor mainly include the following items: when the rated voltage motor is in rated operation state(6384 170kv), the voltage value that DC motor should apply, its unit is v. When the rated power motor is in the rated operation state, the mechanical power output on the shaft, its unit is w(6354 motor 170kv). When the rated current motor is in the rated operation state, the unit of armature current is a when the applied load reaches the rated power.
