○ Brushed DC Motors

A brushed DC motor consists of a rotor made from a copper wire coil and a magnetic stator. The coil ends connect to a commutator, which rotates while maintaining contact with the brush. When DC current flows through the brush and reaches the commutator, it creates a magnetic field, enabling the rotor to rotate by alternating attraction and repulsion with the stator. Despite their simple structure and lack of need for a drive circuit, brushed DC motors incur wear and tear due to the contact between the commutator and brush. This results in regular maintenance needs and can generate mechanical and electrical noise, such as sparks.

○ Brushless DC Motors

Brushless DC motors, as the name suggests, eliminate the need for brushes and commutators. This type of motor features a magnetic rotor and a stator with coils. To generate movement, a drive circuit is necessary to switch the current flow into the coil. One of the key advantages of brushless motors is their longevity and reduced maintenance due to the absence of wear and tear from mechanical contacts. Additionally, because there are no electrical contacts, these motors can handle high currents, producing substantial power output while minimizing noise.

○ Coreless Motors

Among brushed DC motors, coreless motors stand out due to their unique construction, which omits the core of the wire coil forming the rotor. Instead, the rotor comprises a basket-shaped coil with a magnet positioned inside, allowing the rotor to rotate around it. This design results in a lighter rotor with less inertia, enhancing startup and response times. The absence of a metal core also eliminates cogging, ensuring smoother operation with reduced vibration and noise. Moreover, the motor itself can be made smaller and lighter, making it ideal for precision applications.

○ Geared Motors

Geared motors integrate reduction gears within the rotation shaft, facilitating lower-speed rotation with higher torque than typical motors. This configuration is particularly beneficial in applications requiring high torque at low speeds, such as robotics and certain industrial equipment.

● Applications and Manufacturing Expertise
