Product introductionintroduction
1. The small-sized DC cooling fan, with a side length of 20mm and a thickness of 6mm, is designed for ventilation or heat dissipation in micro portable equipment. This product boasts low power consumption, high air volume, and minimal noise. It is easy to install and offers other convenient features. Made from environmentally friendly PBT material, it promotes green environmental protection.
2. Operating ambient temperature
Ball bearing: -30 to +75℃
Sleeve bearing: -10 to +70℃
3. Insulation resistance:
10 meg ohms min, at 500V DC (between frame and terming)
Dielectric strength: 5mA max at 500V/AC/60Hz one minute (between frame and terminal)
4. Functions:
Frequency generator signal option
5.Rated voltage: 12V .5V
6.In the brushless DC motor, the permanent magnet excitation used in the conventional DC motor (on the stator side) was exchanged with the armature winding (on the rotor side), and the permanent magnet excitation was placed on the rotor side, while the armature winding was on the stator side.
7.②The current switching using brushes based on the change in commutator position was replaced with the detection of rotor position signals using Hall elements, and the feedback was sent to the inverter, which then controlled the current.
8.This is the brushless DC motor. Figure 1.7 shows the system configuration of the brushless DC motor.
9.Since the driving voltage supplied by the inverter has become an AC voltage, it can also be considered an AC motor as a permanent magnet synchronous motor driven by AC. However, this book regards it as a separate field of the brushless DC motor.
10.Since the rotating principle is similar to that of the DC motor, the relationship between torque and speed is almost the same as that of the DC motor.
11.With the excellent control performance of the DC motor, it also has various advantages over the DC motor, such as no brushes, superior resistance to electromagnetic interference and longer service life, high efficiency, energy savings, and strong design flexibility, making it easy to design equipment assembly. Therefore, it is not only used in information products such as HDD (hard disk drive) and CD-ROM drive that can take advantage of these advantages, but also widely used in household appliances such as refrigerators and washing machines.
