![]() It is usually measured in N-m when metric units are required and oz-in when English units are required. Other motor characteristics are commonly written as a function of torque. If too much torque is applied to a motor, its output shaft will stall, or stop turning. These characteristics are interdependent and can all be derived from four values: the motor’s stall torque, stall current, free current, and free speed.Ī motor’s output torque is the amount of force with which its output shaft can rotate. They are the motor’s output torque, its current draw, its output speed, its power, and its efficiency, each of which I will discuss in turn. There are several important characteristics of motors that provide information about a motor and its capabilities. – A basic understanding of physics – e.g. This tutorial was made through the Autodesk FIRST High School Intern program. Finally, I will demonstrate how to use what you learn in this tutorial in an example problem and point out extra tools and resources if you want to learn I will then provide information about choosing a gearbox, followed by an overview of the motors and gearboxesĪvailable in FRC. Motor and gear ratio given application requirements. First, I will teach you about motor characteristics. This tutorial will teach you the fundamentals of gearbox design and implementation. Without appropriate motor-gearbox combos, your team will find that your robot does not function as quickly and effectively as intended, and may Why Spend Time Choosing the Right Motor and Gearbox?Ĭhoosing the correct combination of a motor and a gearbox for a given application is very important, both in the FIRST Robotics Competition (FRC) and in actualĮngineering projects. ![]()
