DC planetary gear motor can be divided into brushed DC gear motor and brushless dc motor.
Brush DC motor is operated by a carbon brush, limited life, run out of carbon brush, life will come to an end.
Brushless DC gear motor, compared with the carbon brush motor, long service life, beyond the control of carbon brush, service life.
Brushless dc motor has long life, low noise and high torque characteristics, so the price is higher than the brush dc motor.
Characteristics: stable transmission, large bearing capacity, small volume high torque. Widely used in office automation, home automation, production automation, financial machinery, game consoles and other areas, such as hollow shutter, smart toilet, automatic clothes hanger, electric tools, automatic window opening machine, automatic curtain, glass curtain wall, bank ATM machine, automatic counting machine, notes vending machines and other automatic machines.
