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

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.

With the growing popularity of efficient brushless motors, replacing AC motors with these motors brings several advantages.  In this blog post, we will uncover one of the advantages that can benefit lighter and compact equipment designs.  If we just look at the motors, brushless motors are much more power efficient than AC induction motors.  This means a smaller brushless motor can do the work of a bigger AC motor.  With recent trends in efficiency, brushless motors should be considered during the motor selection process for new designs.

Parallel shaft AC gear motors are the standard configuration in the industry.  However, right angle brushless gear motors are gaining popularity for their ability to minimize the footprint of a machine, such as a conveyor.
