How Motors Work: Learning What Your Options Are in Electric Motors
Motors are used in all sorts of applications and purposes in many aspects of life. They are so valuable that some processes and work needed in a specific industry cannot be achieved without them.
In this guide, we will be handing you out some of the basics of electric motors, including the common types and how you should pick the right one for your needs. In the most generic sense, you should be focusing on answering two questions: which motor type should you choose based on a specific application and which specs matter in the process of choosing that type?
But before we delve into your options, let’s first talk about how motors work. In the most basic sense, electric motors function by converting electrical energy into mechanical energy, the purpose of which is to create some kind of motion. Though the interaction found within the motor between the magnetic field and winding alternating or direct current, force is successfully generated. The moment the strength of the current increases, the strength of the magnetic field also increases.

In today’s modern world, electric motors have a wide range of applications. For instance, they are used in industries for blowers, power tools, pumps, and fans. For small applications and hobbyists, you’d see them in projects that require movement or motion, including that of robotics and modules with wheels.
What You Should Know About Motors This Year
When it comes to DC motors, the two common varieties are brushed and brushless. Aside from the two, there also are vibrating, servo, and stepper motors. Brushed DC motors are the ones we know about for certain because they’re found in many things we use every day. The list of things include vehicles, toys, and appliances. This type of electric motor have contact brushes inside them, which in turn is connected to a thing called “commutator” in order to alter current direction. DC motors aren’t like other electric motors used in large industries because they are affordable to produce and are simple to control.
On the other hand, brushless motors come with permanent magnets in the rotor assembly. They are the motors found in aircraft as well as ground vehicle applications and are easier to maintain than brushed versions.
Things to Consider When Purchasing a Motor
The four single most important attributes in choosing a motor are current, voltage, torque, and velocity. By definition, current is that thing that powers the motor. You cannot choose too much current because it’ll damage the motor. Voltage meanwhile is for keeping net current flowing in a specific direction and for overcoming back current. In literal sense, a higher voltage in the motor corresponds to higher torque. Velocity can also be referred to as speed and the way it works is that motors run efficiently at higher speeds.
So there you have it – the most basic things you should be considering when selecting a motor for a specific project or application. Now it’s your job to do more studying on the other highly specific factors to weigh upon.
