Why a Brushed DC Motor?
The brushed DC motor is the classic motor that is used in applications like motorized toys, appliances, and computer peripherals. This type of motor is inexpensive, efficient, and especially useful for providing high speed and power in a relatively small package.


can combined with gear/ encoder/ gearbox/gearbox+encoder



we design different specification's motor to our customer's special needs






Speed and voltage: speed constant

• rotating winding in the air gap

– in an inhomogeneous magnetic field

– induced voltage Uind (EMF) depends on
• geometry
• magnetic flux density
• number of winding turns
• speed n
• speed constant kn

– inversely proportional to kM

– inversely proportional to generator constant (V/1000 rpm)

Why Is this MotorBrushed?

Electrical contacts on each side of the motor are necessary to reverse the polarity and get the commutator to keep the motor constantly spinning. These contacts are not actually brushes. This type of DC motor is referred to as brushed because early designs of this motor used copper brushes as the contacts. Although in today's motors the commutator is indeed brushed against the contacts, actual brushes are not used.
