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

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.

I will never forget my first engineering project involving motors. I built a small elevator for a science class back in elementary school. Of course, it worked great during the testing phase, but it failed to perform when it counted.
The viscosity change in liquids can vary the torque required for mixing. For AC asynchronous motors such as AC induction motors, the rated speed is affected by load torque fluctuations, which may cause inconsistency in the final product. Is there a better motor for the job?
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 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.
