Motor rated power is an important parameter when a motor type test, which means that when the motor is operating in the power point, the motor can be run continuously and reliably indicate the motor design thermal balance foldable electric bikes. Rated power point general three wheel electric tricycle car motors can be 150W, 80W or 200W or more, the higher the rating point represents better the thermal performance of the motor, the higher the cost.
As the electric vehicle in the idling state is not possible electric tandem bike under a normal weight rider generally up to 30 kg or more, and then drag and other factors normally considered the minimum working point of the motor vehicle (output power) is approximately 80W,three wheel electric tricycle the maximum output power depends on the motor design. Currently the maximum output power is preferably a commercially available electric car can reach more than 200W general, individual poor insufficient motor 200W, the greater the output power range, the better the performance riding.
EV efficiency and efficiency range: EV efficiency electric hub efficiency, control system efficiency and mechanical rotation loss comprehensive embodiment, but mainly depends on the electric hub (motor) efficiency, which can be reflected in the same cell, the same ride under load conditions riding mileage line length, then riding high efficiency long mileage, efficiency is low and vice versa, for the user, to buy more efficient electric car is undoubtedly correct. However, the efficiency of the electric cars need to have an interval, because the motor torque at different efficiencies are different, which means to form a saddle-shaped curve, when the electric motor car and some low-power high efficiency, increase once the output torque, efficiency value of the sharp decline in the performance of this car is often fast flat road, once uphill speed is a sharp decline in consumption levels will increase dramatically.
