It is not random because every factor contributes to the project’s success or failure. You could choose a more powerful motor for a basic project or a low-powered motor for an advanced project. The right external motor selection requires careful analysis. You can do that analysis by reading this blog. Then you will possibly get clarity, which will lead you to choose the right motor. Once you make the right selection, the results will possibly be efficient, and the project will be successful.
AC motors are the most cost-effective and classic version of industrial motors. If you are looking to choose external motors for basic motor work at a low cost, this one could be a suitable choice. Usually, household machines and industrial equipment require basic functions. Therefore, you can try AC motors for operations that are usually basic and low-powered ones.
If you are looking to install external motors in industrial machinery, it is better to choose DC motors. The operational power these machines need can be provided by DC motors. Power tools, elevators, crane hoists, and automotive machines usually require DC motors. These motors are built with a system that supports back-to-back operations. Although there are other factors that affect the performance and conditions, you will find them ahead in the blog.
If the technology is more advanced, you should go for brushed DC motors. They have basic operations that offer support for old technologies and also new ones. The brushed DC motors have carbon brushes to generate current continuously. However, you will have to compromise the speed since it is not suitable for modern appliances. Besides, you can expect efficiency and low initial cost. Toys, electric toothbrushes, wiper motors, and curtain motors usually have brushed DC motors.
Then you have brushless DC motors that are the most efficient and advanced motors. They are the most compatible option for EVs, drones, hard drives, and similar high-tech equipment. There is no carbon brush in them, which means the process is faster. Also, there are electronic chips inside them that provide remote access to users.
Therefore, if you are working on modern appliances for the residential or industrial sector, brushed DC motors are the finest option. The initial cost is higher than that of other types, but the durability and performance are the best among all. Even the maintenance will be less because these motors don’t have carbon brushes and traditional formats.
It is about looking at all the factors before you finalize your decision. Not only does the type of external motor matter, but lots of factors are involved in it. What are those factors? Find out about them below.
How much load are you going to impose on the motor? If you are doing an external motor selection, decide on the load capacity. If you are working on basic machinery like a residential appliance or a low-powered industrial machine, you will need less load capacity. Then you should go for motors that are either AC, DC, or brushed DC types.
Then you should decide the rated power that a motor will operate on. Every motor has a range of operating power, which it runs on. Going over that range could risk it collapse or strain on the coil. The range, speed, and torque will also be part of the selection process. If it is about high torque and speed, it is better to choose a brushless DC motor. The cost will be higher, but the efficiency will be superlative. How many revolutions per minute a motor covers decides the overall speed and power.
If you are installing a motor in a traditional machine, it is better to go with a brushed DC or AC motor. Otherwise, a brushless DC motor is the best for modern appliances.
The efficiency of the machine depends on the kind of external motor installed in it. If you choose a traditional motor type for a modern appliance, there will be a risk of fast battery drainage. Modern appliances require brushless DC motors. These motors are made for fast-speed appliances like EVs, drones, robots, etc. The compatibility level is the key to selecting the motor type for your appliance.
The duty cycle of a motor affects the overheating factor. If the duty cycle is not compatible with the machine’s requirements, there will be a risk of overheating. Then the machine will possibly collapse, and you wouldn’t want that. EVs, HVAC systems, drones, robots, and computers need high duty cycles. Some machines need motors that do not require much rest, and some machines need motors for resting operations. Fans, EVs, and drones need motors that can survive with less rest for continuous operations. However, some motors, like in trimmers, power tools, and similar appliances, need breaks against overheating.
Then you have to look at the resistance level of a motor. It is about the environmental factors that affect the performance of an appliance. Air pressure, heat, moisture, and lots of environmental factors affect the motor’s performance. If you are working on a basic machine for residential or industrial applications, you may need an AC or brushed DC motor. However, you may need a brushless DC motor for that, and of course, for a modern appliance. Industries need robots and devices that can work on repetitive operations without any breaks. Brushless DC motors are the best option to provide compatibility to such machines.
Then the last factor you need to see is cushioning in the motor. You will require additional features that reduce the vibrations and noise in the appliance. As the motor starts moving at high speed, it requires support against friction inside the machine. Especially in EVs, drones, and industrial machines, you will need more cushioning. Basic or traditional machines might not require much cushioning, but you should look at them, too.
These are some protocols you need to select the right external motor for your project. Every factor matters because you will need efficiency in every matter. The torque, speed, range, battery consumption, rated power, and duty cycle are some of the crucial factors in them. Besides, you will have choices like AC, DC, brushless, and brushed DC motors for your project. Each type has a different performance level. So, you will have to choose according to your project needs.
