Improving Stop Accuracy for Start/Stop Conveyors (VIDEO)

Posted by Johann Tang on May 7, 2019 1:32:29 PM

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.

Better Motor Alternatives for Variable Speed Pumps (VIDEO)

Posted by Johann Tang on May 6, 2019 8:03:26 PM

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.

Right Angle Gearheads: Why are Hypoid Gears Better Than Worm Gears?

Posted by Johann Tang on Apr 17, 2019 10:00:00 AM

Historically, worm gears have been known as the most common type of gears used in a right angle gearhead.  Their low cost and robust construction have been sufficient for general purpose applications.  However, they are inefficient at slower speeds (higher reduction ratios), produce a lot of heat, take up a lot of space, and require maintenance.  As efficiency standards became increasingly important globally, another type of gear is being adopted for right angle gearheads.

Torque Limit Application Example - Bottle Capping with BLDC Motors (VIDEO)

Posted by Johann Tang on Feb 15, 2019 1:00:00 PM

For applications where torque needs to be limited, an external mechanical torque limiter is typically required in addition to the motor system.  When the torque exceeds the limit, the torque limiter will either decouple the load or limit the torque by slipping.  An electric motor system's built-in torque limit function can simplify machine designs by eliminating this extra component.

Shorten Design Cycles for Mobile Robot Applications With Built-in Features & Functions

Posted by Johann Tang on Dec 15, 2018 12:00:00 PM

In the market of electric motors, there are products designed for general purpose applications, and there are motors designed for specialized applications, such as automated guided vehicles (AGVs) or autonomous mobile robots (AMRs).  While standard, general purpose motors work for most applications such as factory automation, sometimes, it may help shorten your design cycle by going with a motor system that already offers the features that you are planning to implement into your design.  In this post, we will summarize some of these features.

Easily Synchronize Speeds of Multiple Motors (VIDEO)

Posted by Johann Tang on Oct 15, 2018 9:00:00 AM

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.

Designing Lighter Equipment by Reducing Motor Mass

Posted by Johann Tang on Oct 1, 2018 8:32:18 AM

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.

Minimize Machine Footprint with Right Angle Gear Motors (VIDEO)

Posted by Johann Tang on Oct 1, 2018 8:31:15 AM

Parallel shaft gear motors are the standard configuration in the industry.  However, right angle gear motors are gaining popularity for its ability to minimize the footprint of a machine, such as a conveyor.  Another factor that should be considered is the type of gears used in the gearhead.  While worm gear technology is popular, its gear efficiency can vary from 50~90% depending on gear ratio.  On the other hand, hypoid gear technology keeps its efficiency at 80~95% regardless of gear ratio.  Higher gear efficiency allows more torque to be transferred from the motor to the load shaft, and sometimes allows even smaller motors to be used.
