From Testmybike we tell you how the efficiency of motors varies according to the power range and why it is important and necessary to unify criteria.
What is the efficiency of an electric motor?
The efficiency of an electric motor is the relationship between the electrical power it consumes and the mechanical power it delivers. That is, it is the measure of how much energy is used to move the bicycle and how much is lost in the form of heat (derating), noise, or vibrations.
La eficiencia de un motor eléctrico no es constante, sino que depende del rango de potencia en el que se trabaja. Por ejemplo, un motor puede tener una eficiencia del 90% cuando consume 100 vatios, pero solo del 60% cuando consume 600 vatios. Esto significa que a mayor potencia, mayor consumo y menor rendimiento.
Why is standardization important in electric bicycles?
Actualmente, no existe un criterio único para medir y comparar la eficiencia de los motores de las bicicletas eléctricas. Cada fabricante puede dar los datos que le convengan, sin especificar el rango de potencia en el que se han obtenido. Esto dificulta la elección de los consumidores, que no pueden saber con certeza cuánta autonomía tendrán sus bicicletas.
From Testmybike, we believe it is necessary to establish a standard that allows for the objective and transparent evaluation and comparison of the efficiency of electric bicycle motors. That's why we think that the information about the efficiency of the motors in their different power ranges should be provided, which in the case of the Fazua Ride 60 motor would be from 100 to 600 watts, offering detailed information to users.
How can you know the efficiency of your electric bicycle?
If you want to know how your electric bicycle behaves in terms of efficiency, you can continue visiting our website www.testmybike.com and check the results of our tests. Here we will publish the efficiency data of the main brands, as well as other parameters that we will explain in future articles.
