Welcome to Oriental Motor's "Engineering Notes" Blog:

Knowing how to use a product properly can make a huge difference in its performance and life.  For example, knowing how to maintain cast iron pans properly can make them last longer.  With electric motors, understanding the factors that affect motor life is the first step to extending life and decreasing costs in the long run.

An easy way to alter the speed and torque characteristics of a stepper motor is to connect it to a different type of driver or change its wiring configuration.  However, there's more to it.  Knowing the pros and cons between "unipolar" and "bipolar" can make or break your stepper motor performance.

For automated factories, motor failures mean lost production and lost revenue.  Being able to identify the specific issue in advance and its location is critical to maintaining production efficiency.  To be successful, extra sensors must be added to detect abnormalities.  There may be an easier way.

Oriental Motor offers many pre-assembled geared motors for quality, consistency, and reliability.   In addition, gearheads from our industry partners increase the torque range of our motors further to accommodate more applications.  Here are some advantages of geared motors.

For someone who has never had experience wiring I/O for motion control, it can be scary the first time.  If devices are not wired correctly, it can cause a range of issues from a motor simply not doing what's expected to irreversible product damage.  I still get that nervous feeling before I press the START button on a demo.  Murphy's Law, anyone?

The significance of position control accuracy of motors varies depending on the application.  For an AGV in a farm with DC motor-driven wheels, position control accuracy is probably not as crucial as a surgical robot where incisions are controlled by servo motors or stepper motors.

Besides load torque, acceleration torque, speed, and load inertia, overlooking certain sizing parameters during the motor sizing process can literally make or break your machine.

A gripper is typically an end effector that is installed at the end of a robotic arm or on a cartesian robot and can be used to grip parts in order to transfer them from one location to another.  However, there's more to it than just closing the jaws to pinch a part.  

Now that we understand the calculations behind load torque and load inertia, we're a little closer to motor selection.  You might be wondering why I separated load torque and acceleration torque calculations.  That's because in order to calculate for acceleration torque, load inertia and speed must be calculated first.
