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

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?

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?

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.

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.

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

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.

An AC motor can be simple to use, but its speed changes according to the size of the load or amount of voltage supplied.  For an application where keeping a uniform speed is important, there is another type of motor that can improve performance.
