With the changes and development taking place in the industry, ac electric motors have never been so diverse and adaptable. This is especially important because the choice of motor is one of the most crucial factors when planning a motion control.
You want to make sure the motor aligns with the purpose and the overall performance of the system. Fortunately, this is no longer difficult as the variety of options available in the make-in market makes it possible to have any motor design to fit just about any system goal.
Here are some of the most popular electric motors used today;
Linear Motors
This is a great option especially if you are looking for a faster and more accurate motor. Of course, there are many accurate types of electric motors but this stands out when you have to choose compared to models such as rotatory motors. They have an unrolled stator and motor and produce linear force along the length of the device.
Stepper Motors
These have an internal rotor, which is manipulated electronically by magnets on the outside. The rotors also come in two types; they can be made of soft metal or permanent magnets. How they work is that the rotor teeth move in fixed increments as the windings are energized.
DC Brushless Motors
When DC Brushless motors were first developed, they were to be used to achieve high-level performance in smaller spaces than their counterparts; DC Brushed Motors. They are also smaller compared to other ac motors. How they work is that they use an embedded controller to operate in the absence of a commutator.
DC Brushed Motors
Just like in the DC Brushless Motors, the commutator is one of the most important components to facilitate operations. The current flow is usually determined by the stator orientation.
Direct Drive
If you are looking for a high-efficiency motor, then you might as well want to check out direct drive motors. The low-wear technology implemented on the motor sure replaces the conventional servo motors. They are also way easier to maintain and accelerate more quickly.
Choosing the Right Electric Motor for your Project
Choosing the right motor comes down to your project requirements. Here is how you go about it;
Know the Types
The first thing is to know that there are three main types that you can choose your motor from. This includes the AC asynchronous motor, which you can get in single or three-phase, The synchronous motor and the stepper motor. Once you get to know the different types in these categories and how they work, it will make it easier to determine which one you need.
Determine your Application
This is another super important factor before you even start to choose the motor. You first need to determine where you are going to use the motor. Some of the factors you want to consider include;
- If you want the motor to run continuously
- Is the application dynamic
- Do you require precise positioning and more.
The Technical Specifications of the Motor
This is also going to be determined with the application and the movement you require. It is necessary to know the power, the speed of the motor, and the torque. You also want to determine the size of the motor. You must know the amount of space you want the motor to take up as well as how it will be mounted.
Industrial Environment
When it comes to the industrial environment, you want to consider the dimensions and how solid the motor is. Know that for each type of industrial environment, there is a format. It may be damp, high temperature, explosive, or corrosive, and more of such. Others have motors with a dirt-resistant casing, reinforced waterproof, and shock-resistant, for harsh environments.
