I am starting today's video by greeting everyone on behalf of Micro Project Bangla Channel. In today's video, I will discuss about the small and big motors of DC rechargeable fans. In this video you will know what type of motor takes the amount of ampere and current. This is very important to know when it comes to making rechargeable fans. Because there are some motors that draw more current but work less. And taking more current will not provide long backup time from the fan made with that motor. So in making a rechargeable fan it is important to know how much current a motor draws. So without further ado let's go to the main video.
Guys you can see I have taken quite a few motors. These motors are mostly used in making fans. There are also different types of motors that are used in making fans. However, today I will show you an experiment with these motors. First of all you need a digital multimeter. As you can see I took a multimeter. Now between the two proofs of the multimeter, the red proof should be opened from DC and put in ampere. And the meter should be set to amperes. Because to determine the power of the motor, the amount of amperes the motor draws must be multiplied. As you can see I have fixed everything as usual Micro Project Bangla.
Now I need a battery. As you can see I have taken a battery of high-power 4 volt 4 ampere. Because the motor that I will check now is a 4 volt motor. So I bought a motor. I connected the negative wire of the battery to one end of the motor. And the other positive wire of the battery will be connected to any one of the proofs of the multimeter. There is no problem if negative positive reverses here.Micro Project Bangla Now connect the other proof of the meter to the motor. You can see the amount of current the motor is drawing as the meter shows. Now I will check this three volt motor. So you can see what amount of current it is taking which is showing on the meter.
Now I will check by attaching a fan to the motor, because if the fan is attached, the load of the motor will be read and if the load is read, it will be known how much ampere current it receives. So I attached the fan to the motor. Now I will give the connection to the motor. It appears that it is receiving more ampere than before. A motor this small draws more than 1.9 to 1.8 amps of current in load mode. Micro Project Bangla Now I will again install a fan on the four volt motor and see how many ampere current it receives in load mode. So I put the fan on, I can see from the connection that it is drawing 1.3 amperes of current. That means that the larger motor draws comparatively less current than the smaller motor.
Now let's check the 12 volt motors. As you guys can see I have quite a few 12 volt motors. There are a total of three types of motors, all 12 volt motors. , among these 12 volt motors, I will experiment to show which type of motor draws what amount of amperes. Micro Project Bangla Of the motors I have now, the larger motor is used in the 16 inch charger fan. And small motors are used to make 8 inch DC fans. Which are known as solar fans. And these big motors are mainly used to make charger fans. These I collected from charger fan. Micro Project Bangla
