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.
Welcome to Oriental Motor's "Engineering Notes" Blog:
Products and technology are only valuable when coupled with skilled people and services to support them. ORIENTAL MOTOR U.S.A. CORP. has dedicated over 33 years to establishing a service and support system to better serve customers. It is our goal to provide the best product and service from the design phase, through the sale and beyond.
Our blog will feature:

Oriental Motor offers many pre-assembled geared motors for quality and consistency. In addition, gearheads from our industry partners increase the torque range of our motors further to accomodate for more applications.
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. In this post, we will explain how to properly grip a load while preventing damage.
Now that we understand the calculations behind load torque and load inertia, we're two steps 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.
Proper sizing of a motor requires that 3 criteria must be met: torque, load inertia, and speed. For the first part of this Motor Sizing Basics series, I will be explaining what load torque is, how to calculate it for specific application examples, and how it fits into the torque requirement for the application.
