The difference between motor and brushless motors

2019-08-19

Brushless Dc Motor and brushless motor has difference, actually very simple, has a brush DC Motor equipped with commonly used brush and commutator. Have a commutation of brushless dc motor has been through the graphite (both carbon block is also called the carbon brush) or precious metal brushes and mounted on the rotor commutator ring to make contact, the motor running, the longer the longer brush friction thinning of the brush will eventually rupture, the motor run out of life, and the commutator also hair black, need to replace the motor.
While by hall sensor brushless motor rotor position feedback control circuit, back to know the exact time of the motor phase commutation. Most of the brushless motor manufacturers production positioning with three hall effect sensors. Because of brushless motor without brush, so also does not have relevant interface, therefore more clean, less noise, no abrasion, wear and tear is small, in fact, no maintenance, longer life. But at the same time the price of the brushless motor is ten times the size of brush motor, common micro brushless motor price need to more than 30 yuan, and ordinary miniature have brush motor price is roughly in 3 yuan of above.
Compared with brush motor has better performance and wider application market.
Shun cheong motor: professional produce a brushless dc motor, Gear Motor manufacturer, welcome to choose and buy!
