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

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 is not working like it's supposed to.  What do you do?  Before replacing the motor, here are three ways to start troubleshooting your AC motor with a circuit tester.

For a permanent-split capacitor type AC motor (also known as capacitor start and run AC motors), a capacitor is required for proper operation.  Enjoy a cup of coffee as we explain why.

AC motors have the same operating theory, but by changing its design a little, you can modify its characteristics to suit certain applications better.  In the last post, I focused on AC induction motors for unidirectional applications.  In this post, I will explain what makes AC reversible motors and AC electromagnetic brake motors ideal for start/stop, reversing, or vertical applications, and demonstrate how to operate them.

AC motors are simple to control, rugged, and cost effective for general purpose applications.  These reasons are why they are the most popular type of electric motor across various industries.  In this post, we will briefly introduce induction motors and demonstrate how to operate these motors.

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.

Are you using motors for a start/stop conveyor or similar application?  While AC motors are a common choice for conveyors, there is a unique speed control motor solution available that could improve stop accuracy as well as reduce footprint and cost of machine designs.

What motors do you use for pumps?  For variable speed pump applications that typically use 3-phase AC induction motors with variable frequency drives (VFDs), there is another type of motor that can transfer fluids more consistently and help reduce footprint.

As efficiency becomes increasingly important, another type of gear is being adopted for right-angle gearheads over the common worm gears.

There are a variety of ways to synchronize the speed of multiple motors.  In this blog post, we will explain another advantage of using brushless motors systems, which is its ability to set speeds accurately and be able to synchronize speeds on multiple axes easily .  Brushless motors utilize built-in hall-effect sensors to regulate speed.  Even if the load, input voltage, or temperature fluctuates, the speed regulation will always be under +/-0.2% or better.
