When it comes to electric motors in our day-to-day appliances, a noticeable difference exists in the noise levels of electric vehicles (EVs) and fruit blenders. The question arises: why does this discrepancy exist?

Upon closer examination, it becomes apparent that the answer lies in the tale of two distinct technologies.

Fruit blender manufacturers often opt for the cheapest, least efficient electric motors available, which tend to be intentionally loud to create the illusion of greater power.

On the other hand, EVs cannot compromise on motor quality, utilizing meticulously designed, reliable, efficient, and quiet motors.

This discrepancy stems from the differences in construction, efficiency, and the importance of design and control.

Construction and Efficiency

Fruit blenders typically employ brushed open motors that are not only less expensive to manufacture, but also susceptible to water damage and energy wastage through sparks and noise.

In contrast, EVs utilize encapsulated motors featuring permanent magnets or induction, increasing efficiency and durability while reducing noise levels.

EV motors are carefully controlled with electronics, further contributing to a quieter operation compared to cheaper motor options.

The Importance of Design and Control

The design disparities between fruit blenders and EVs highlight the critical role of electronics in managing motor operation.

While fruit blender manufacturers prioritize cost savings over noise reduction, EV manufacturers implement advanced electronic control systems to regulate motor function, resulting in a quieter driving experience.

Looking Forward: What Lies Ahead

The contrast between the motor sounds of fruit blenders and EV cars serves as a vivid reminder of the impact of engineering choices on our daily experiences.

As technology continues to evolve, perhaps we will witness a convergence of quiet operation in all electric appliances, from blenders to vehicles, making noise a relic of the past.
