Electric tricycle motor and controller to match the power of the principle of power

Conventionally, electrical system load power is generally defined as 75% of the power control part , that when the motor controller to choose optional 350W 500W, this configuration ensures that the vehicle is very low failure rate . Most manufacturers 350W motor controller is also used 350WW, even 500W motor controller also use 350W; Some controller manufacturers 350W controller marked as 500W, to create the illusion of manufacturers . As the electric tricycle pull people up the goods , the load Adult tricycle is much larger than the electric bike and overload phenomenon occurs frequently, because the proportion of damage caused by the irrational support will be greatly increased . 6 , the electric tricycle battery capacity and the parameters of the controller ? Electric tricycle battery capacity is mainly concerned with the current limit controller , battery 25A maximum current limit controller with the capacity of 20 Ah to 18 ~ 20A for the best. Battery 35A maximum current Electric Bikes limit controller with 36 Ah to 22 ~ 27A for the best. Battery 45A maximum current limit controller with 45 Ah to 30 ~ 35A for the best. On the battery 60 with the maximum time -limit controller 60A to 40 ~ 45A is preferred. Battery 120A maximum current limit controller with 120 Ah to 80 ~ 100A for the best. Because SACS governor did not limit, the maximum current up to 100A or more, so can not be selected when the battery capacity is small , otherwise an undervoltage use will not go . Permanent magnet brush motor is best not to use the series excitation governor , motor burn easily , but also volatile magnetic .
