Nema 11 28 MM*28 MM Low Noise Dc Brush Gear Motor 5000 RPM 24 V
Brushed DC motors use an armature, which acts as a two-pole electromagnet. A commutator is a mechanical rotary switch that reverses the direction of current twice per cycle. In contrast, a brushless motor uses permanent magnets as its outer rotor. And brushless DC motors don't have brushes, which means they require less maintenance and are a bit more efficient than brushed motors.
Hetai's high power density BLDC DC small motor provides unparalleled speed and torque performance, ideal for automation applications such as electronic assembly equipment that requires constant pick and place operations. Durable and high-performance, energy-efficient Athlonix motors are also used in medical pumps, safety door locks, robotics and many other applications.
