Electric Tricycle Bike Motor Ratings and Efficiency
Feb 06, 2019

Under the rated voltage and rated torque working conditions, the speed and output power of the electric tricycle bicycle motor shall be within the deviation range specified in the technical documents. Under the rated voltage and rated torque conditions, the motor efficiency should be no less than 75%. Under rated voltage, 50% and 160% rated torque, the efficiency of the motor should be no less than 70%.

 

For a qualified electric tricycle bicycle, the motor must not be mechanically deformed or make an abnormal sound within 2 minutes of no-load over-speed operation at 1.2 times rated voltage. The motor should withstand 2.5 times the rated torque at the rated voltage for a duration of 1 min and should still operate normally after restarting.

 

Moreover, the controller of the electric tricycle bicycle should be in normal operation, and the efficiency of the controller under the rated voltage and rated input current conditions should be greater than 95%. The controller shall be capable of withstanding 2.5 times the rated input current for a short time overload of 1 min. The controller of the open loop control shall have a voltage regulation function; the controller whose outer loop is the speed closed loop control shall have a speed adjustment function; the controller whose outer loop is the torque closed loop control shall have a torque adjustment function.
