The performance of a motor is determined by factors such as its structure, accessory materials, operating environment, and selection. In this article, we will focus on the selection of motors for our products. There are various types of motors available, including brushed motors, brushless motors, and geared motors, each with their own advantages and disadvantages in terms of cost and performance. For our products, we primarily use brushed and brushless motors, depending on the operating environment and cost.
When selecting a motor, it is important to consider the following factors. Brushed motors have the advantage of being relatively low-cost, with high torque and strong starting and acceleration ability, making them suitable for short-term, high-load applications such as short-distance transport and refilling. They can also withstand short-term overload and are easy to maintain and repair. However, brushed motors have a relatively short lifespan and require frequent replacement of the brushes. They are also prone to electromagnetic interference and noise issues, and have relatively low energy conversion efficiency with low power density.
On the other hand, brushless motors have the advantage of a longer lifespan of up to tens of thousands of hours, with no need for regular replacement of brushes. They also have high efficiency with high power density, and generate less electromagnetic interference and noise. Brushless motors are suitable for applications that require high lifespan and long-term operation, such as constant temperature cycling and long-distance transport. However, they have a relatively high cost and weak starting and acceleration ability, and are not suitable for long-term high-load operation.
Our micro water pumps and air pumps are designed to select motors based on the customer's actual usage. Both brushed and brushless motors can be used in our pumps, depending on the specific requirements of the application. In general, brushed motors are suitable for applications with high instantaneous load changes, while brushless motors are suitable for applications that require high energy efficiency and low noise and electromagnetic interference.
