Release time:

2024-12-11

Robots: DC brushed motors are commonly used in the joints of robots to achieve flexible motion control.

DC brushed motors are generally used in the following fields:

Robots: DC brushed motors are commonly used in the joints of robots to achieve flexible motion control.
Automobiles: DC brushed motors have also been widely used in electric assist systems such as electric windows, wipers, and electric seats.
Household appliances: DC brushed motors are widely used in household appliances such as vacuum cleaners, washing machines, and power tools.
Automation equipment: In automation equipment such as conveyor belts and robotic arms on assembly lines, DC brushed motors play an important role.
Electric models: DC brushed motors are a common power source in electric models such as remote-controlled cars, ships, and airplanes.
Electronic toys: Due to their simple structure, easy control, and low cost, DC brushed motors are commonly used in inexpensive electronic toys.
Fans: Various fans and low-end electric bicycles also commonly use DC brushed motors.
Advantages and disadvantages of DC brushed motors:

Advantages: Simple structure, easy control, low cost. Due to the presence of electric brushes and commutators, DC brushed motors only require two cables between the power supply and the motor, saving space and cost for wiring and connectors. In addition, using MOSFET/IGBT switches can provide sufficient performance and the control system is relatively inexpensive.
Disadvantages: Due to the presence of electric brushes and commutators, brushed motors have complex structures, poor reliability, multiple faults, heavy maintenance workload, short lifespan, and are prone to electromagnetic interference caused by commutation sparks.
