Note that there are three main types of dc fans: two-wire, three wire, and four-wire. The two-wire fan has two pins – power and ground. This fan can be controlled either by varying DC voltage or by ...

Diodes Inc.has announced the introduction of a pair of all-in-one single-phase 12 V fan motor drivers for low to medium voltage brushless DC fan control in consumer, home appliance, industrial and ...

In many new designs, smaller packaging, ever-shrinking boxes, and high-power ICs can cause heat problems. Fans can minimize overheating, but unfortunately, they are prone to mechanical problems, ...

4-wire DC fans include hall-effect sensors that sense magnetic fields generated by the rotor as it spins. The output of the hall-effect sensor is a pulse train that has a period inversely proportional ...

This is a very cool electronic project to control dc loads using a very cheap and reliable design. This video also explains ...

In this exciting video, we dive into the world of controlling high voltage DC motors and the intricate process of designing a custom circuit for them. Join us as we explore the challenges and ...

This dc motor speed-control circuit uses standard, available components; light impinging on two independent phototransistors establishes the motor's speed. Motor speed can be adjusted by the light ...

Jaro adds 40 × 20-mm and 40 × 28-mm IP68-rated DC axial fans for demanding environments, offering protection from dust, water ...
