Disadvantages of Brushless Motor
For most people who have brushless motor will say brushless motor is expensive. That’s true. But have you think
about what cause the problem.
Brushed motors are cheap to produce, but the brushes wear out from rubbing against the contact point and axle.
Friction from this contact also impedes performance. For brushless motor, as it appeared later than brushed,
regardless of technology or materials, there are big challenges. Also, electric controller is required to keep the
motor running. It offers double the price of the motor. The high costs cause the final expensive price. Technology
is always in advance, we should believe that higher quality motors will be notified by us.
