How to Choose an Electric Motor: Introduction and Basics
There are so many factors to consider when choosing an electric motor that sometimes it's tough to know where to begin. Groschopp's ten-part video series, "How to Choose an Electric Motor" talks you through the process of motor selection by using real-life scenarios and providing tips and resources along the way. In this first video we introduce the basic concepts of electric motors.

00:00:02 [Music] hello this is Janet and I'm Joe with growshop and welcome to our video series how to choose an electric motor we know that selecting the right motor can be a complicated process perhaps you're in the early stages of a project that requires a motor but you aren't sure what type of motor best fits your application maybe you're in charge of
00:00:30 purchasing motors and you'd like to better understand which specifications are important or maybe you're just making sure the motor in your product is the right one for the job whatever the case our primary goal is to help you feel more comfortable selecting motors by the end of this 10 part video series you'll have the information and tools needed to feel more confident selecting
00:00:51 the optimal motor for your project our approach will be to give you background of the motor types as well as help you understand when and why one motor should be used over another we'll show you how to take advantage of simple modifications to get the best motor for your application let's begin with a quick overview of motor basics in our following videos
00:01:11 we'll look at a checklist of application criteria discuss the four motor types their construction characteristics advantages and disadvantages and learn how to interpret performance curves for speed torque and efficiency finally to demonstrate the concepts we cover will present a few examples of real-life applications be sure to check out the video descriptions for links to
00:01:33 downloadable tools that help with the selection process so Joe why don't you get us started sure Janet let's jump into some motor basics as you know the purpose of a motor regardless of the application is to change electrical power to mechanical power no matter the motor type this power conversion is achieved by inputting an electrical current to
00:01:53 create attracting magnetic fields that induce rotation of the shaft this rotation provides torque to move or hold a load in a wide variety of applications in AC motors this rotation happens because of magnetic fields caused by alternating current in the stator coils and the resulting current induced in the rotor in DC and brushless DC motors rotation happens when the magnetic field
00:02:16 created by the permanent magnets and commutation of the wound coils interact the purpose of a motor might be straightforward but actually determining which motor is best for your application can be a challenge as will discover available input power application constraints environmental conditions and load requirements can all affect the motors performance and remember every
00:02:37 application will have its own distinct parameters for input and output power keep watching in our next video we dive deeper into these application criteria for more information about growshop or any of our products check out our website at [Music] you you
