As the power source of an electric wheelchair, the motor is an important criterion for judging a good or bad electric wheelchair. Today, we will take you through how to choose a motor for an electric wheelchair.

Electric wheelchair motors are divided into brushed and brushless motors, so is it better to have brushed or brushless motors?

Many people know that there are two types of motors in wheelchairs, brushed and brushless. Simply put, brushed is cheaper and brushless is more expensive, so what is the difference between these two types of motors?

Firstly, from a technical point of view, brushed motors are more mature than brushless and therefore cost much less.

Brush motors are simple in structure and easy to produce, and have been in widespread use since their invention, and the technology has been iterated for over a hundred years now. Brushless motors, on the other hand, were invented in the nineteenth century, but the level of technology in the past was not sufficient to overcome the shortcomings of their practical application, and it is only in recent years that they have slowly come into commercial operation.

Brushless motors are expensive for a reason, the biggest advantage being their silence. Brush motors inevitably generate noise due to the friction of the carbon brushes on the surface of the coil during operation. Brushless motors, on the other hand, have fewer brushes and almost no wear and tear, so they are less noisy and run smoothly.

And because of the difference in operating principle, brushless motors have a very stable power output during operation, the speed hardly changes and the power consumption is much lower than with brushes.

In terms of maintenance costs, a brushless motor is theoretically a maintenance-free motor with a service life of tens of thousands of hours. Brushed motors have brushes that wear out and generally need to be replaced after a few thousand to 10,000 hours.

However, the carbon brushes only cost a few dollars to replace, while brushless motors are basically beyond repair when they break down, so the actual maintenance cost is still cheaper for brushed motors.
