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.

Choosing the Right Type of Stepper Motor for Your Application (VIDEOS)

Posted by Johann Tang on Nov 12, 2018 8:30:00 AM

Stepper motors are popular for their ability to position accurately as well as their ease of use.  Both the amount of rotation and the speed are controlled easily with the same digital square wave pulse signal.  Unlike servo motors, stepper motors do not need an encoder to operate.  Example applications of stepper motors are CNC machines, index tables, robotics, scanners, and more recently, 3D printers.

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.
