In the world of electric vehicles, the power of an electric tricycle is the key. Generally speaking, the motor power is between 500W and 2000W, of which 500W and 800W are suitable for daily use, while 1000W and above provide more powerful power support. To run fast, the power of the motor is the determining factor. Following the formula P=I*U, the increase in voltage means the exponential increase in power, that is, the voltage doubles and the power can be increased to about 7 times the original.
However, the calculation of actual mileage is not a simple multiplication. Taking a 1000W motor as an example, with a 60V and 50AH battery pack, the theoretical discharge time is the battery capacity divided by the current. Assuming a speed of 47 km/h, the theoretical driving distance can be calculated to be about 141 km. However, considering the healthy maintenance of the battery, it is usually necessary to retain 20% of the power, so the actual mileage is about 60% of 140 kilometers, or about 56 kilometers. The specific value needs to be flexibly adjusted according to the actual situation.
When choosing an electric tricycle motor, you need to consider the following important factors:
Starting performance: The motor should have good starting torque to ensure that frequent start-stop and acceleration requirements are met.
Constant power range: A wide constant power range is the key to meeting the high-speed driving of electric vehicles.
Speed regulation capability: The motor needs to be able to provide high torque at low speeds and maintain high power at high speeds to meet the different needs of drivers.
Efficiency: The motor should have high efficiency to ensure that it can provide at least 85% efficiency under typical driving conditions to extend the mileage.
Size and weight: The motor should be compact and lightweight to improve the overall performance of the vehicle.
Reliability and durability: The motor needs to have excellent working stability and durability, be able to operate normally in various environments, and have low noise and easy maintenance.
Energy recovery: Combined with the controller, the braking energy can be effectively recovered to achieve energy reuse.
