The difference between brushed and brushless DC motors is whether or not a common brush-commutator is used.
The difference between brushed and brushless DC motors is whether or not a common brush-commutator is used. Brushed DC motors use a graphite brush that makes contact with a commutator ring on the rotor to achieve commutation.
Brushless DC motors, however, use Hall sensors to feed back rotor position to the control circuit, allowing it to accurately determine the timing of motor phase commutation. Most brushless motors produced by manufacturers have three Hall effect position sensors. Because brushless motors have no brushes, there are no associated interfaces, resulting in cleaner operation, less noise, virtually no maintenance, and a longer lifespan.
Meileke Technology's Moons brand brushless DC motors offer a wide range of operating parameters. The 42 brushless DC motor has a wide driving voltage range: 24VDC-48VDC, and a wide power range: 30W-105W; The 57 brushless DC motor has a wide driving voltage range: 24VDC-220VAC, and a wide power range: 60W-200W; The 80 brushless DC motor has a wide driving voltage range: 24VDC-48VDC, and a wide power range: 100W-300W; They feature a wide speed control range of up to 5000 RPM, high speed stability, high efficiency, low temperature rise, small positioning torque, smooth operation, low noise, and low vibration.
Compared to existing products on the market, Moons brushless DC motors have the advantages of lower noise, less vibration, and a longer service life due to design innovation. These products can be widely used in factory automation, pumps and valves, solar energy equipment, automotive equipment, etc.
