How to choose dc plastic gear motor
I once had a friend in the automotive industry. I chose a TW electronics here and took a DC geared motor. The test result is very OK, which means the cost is higher than that of the single motor. So he went to the market and found an RF370 single motor, telling me that the price of this single motor is very good, as long as a few dollars, the benefits of blowing all the wind, the only thing that can not be satisfied is that the speed is too fast, the torque is not enough. Now I want to use our products and ask me to lower the price for him. In fact, everyone knows how the price reduction of the geared motor can't reach the price of a single motor. What's more, the customer took a non-OK product to bargain, meaning nothing.
Regarding the selection of the motor, whether you are a dc plastic gear motor, a DC brushless motor, a large torque geared motor, or a small torque single motor, it is actually very doorway, and it is very technically elegant. Many non-professional demanders usually ask for the "small size, the better the torque, the better the noise, the better the noise, and the cheaper the better." In fact, this kind of psychology not only increases the cost of the product, but also does not achieve the desired effect.
In fact, when selecting a motor, the first geared motor must be able to drive the rated load to the desired speed under standard voltage to achieve its function. If this is not enough, consider the noise, shape and price, etc. Generally, we must determine the performance of the motor, and then we are to optimize the sound and shape of the motor, not to reverse the primary and secondary.
Then we should consider the environment in which the motor is used when selecting the motor. For example, if the product is used in a hall or a square, wouldn't we use a high-quiet motor? This is nothing more than increasing the cost of the project, which seriously causes the project to fail; for example, I want to use the motor to make a round-trip motion. When designing, the structure is blocked to achieve stop and reverse. At this time, it is necessary to select a motor with a suitable torque, not to say that the larger the torque, the better. If the torque exceeds the capacity of this structure, will the motor top the structure? There are many similar cases that will not be explained one by one.
The following two motors of 16mm diameter are listed, not because of the same diameter, but can be used in the same place. We have to choose according to the relevant parameters of the product for different projects. For example, the GM16 screw version has a large gear module and the cover material is steel plate. It is more suitable for large load places, so it is wear-resistant and has a long service life. The GM16 riveting version can achieve a reduction ratio of 1/3, so choose This can be considered at higher speeds.
