42mm brushless dc motor testing


A brushless DC motor is essentially flipped inside out, eliminating the need for brushes to flip the electromagnetic field. In brushless DC motors, the permanent magnets are on the rotor, and the electromagnets are on the stator.

Brushless motors have significantly higher efficiency and performance, and a lower susceptibility to mechanical wear than their brushed counterparts. Brushless motors offer several other advantages, including: Higher torque to weight ratio. Increased torque per watt of power input (increased efficiency)

The advantages of a brushless motor over brushed motors are high power-to-weight ratio, high speed, nearly instantaneous control of speed (rpm) and torque, high efficiency, and low maintenance.

It is high performance motor that provides large torque per cubic inch over a vast sped rang. BLDC motors do not have brushes which make it more reliable, high life expectancies, and maintenance free operation. There is no ionizing sparks from the commutator, and electromagnetic interference is also get reduced.

If you are looking for a motor with a long life expectancy, consider a brushless motor. Brushed motor life is limited by the brush type and can attain 1,000 to 3,000 hours on average, while brushless motors can attain tens of thousands of hours on average, as there are no brushes to wear.
