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

Proper grounding is necessary for electrical devices for different reasons, but why do we do it?

No matter how many functions a product offers, without an intuitive, easy-to-use software, those functions can be difficult to implement.

STO, or "Safe Torque Off", is a dedicated, built-in safety circuit function that makes safety easier to manage for motion devices, such as an industrial robot.  It is part of the overall safety system designed to prevent injuries or damage.

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.

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.

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?

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.

Other than torque or speed, another factor should be considered when sizing motors.
