Minimizing the Effect of Load Fluctuations for Mixers

Posted by Johann Tang on Jun 30, 2020 12:00:00 PM

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?

Monitor Your Machine Like a Traffic Light System

Posted by Johann Tang on Jun 19, 2020 8:00:00 PM

For automated factories, motor failures mean lost production and lost revenue.  Being able to identify the specific issue in advance and its location is critical to maintaining production efficiency.  To be successful, extra sensors must be added to detect abnormalities.  There may be an easier way.

The Proper Way to Use a Gripper

Posted by Johann Tang on Mar 5, 2020 5:11:16 PM

A gripper is typically an end effector that is installed at the end of a robotic arm or on a cartesian robot and can be used to grip parts in order to transfer them from one location to another.  However, there's more to it than just closing the jaws to pinch a part.  In this post, we will explain how to properly grip a load while preventing damage.

Understanding Preventive vs Predictive Maintenance: Which is More Efficient?

Posted by Johann Tang on Aug 20, 2019 2:58:24 PM

Along with the advancement of industrial technology, the method of maintaining motion control components of a machine, such as motors, drives, and sensors, has also evolved.  The most common method of maintaining a machine after a failure has occurred was the traditional method.  Realizing the need for improvement, maintenance personnel started to estimate life and replace motion control components before they fail.  More recently, with the advancement of IIoT (Industrial Internet of Things) and real-time availability of status data, another method was born.  While the two newer methods have the same goal in eliminating machine downtime, only one does it efficiently.

How Easy Is It to Build a Robot?

Posted by Johann Tang on Jul 19, 2019 8:31:19 PM

Robot adoption is increasing in many industries due to global efforts in reducing long term costs, maintaining quality, and freeing up time for humans to do "human" tasks.  For example, by using a robot to clean floors or restock shelves in a supermarket, human employees can spend more time helping or selling to their customers.  A company can either tap into this robotic trend by buying ready-made robots, or by making their own with less cost.  If engineering resources are limited, selecting the right components can reduce the difficulty and time for the build.

Benefits of an Absolute Rack and Pinion System

Posted by Johann Tang on Jul 2, 2019 3:25:24 PM

There are many mechanisms that convert rotary motion of an electric motor to linear motion, such as belt/chain drives, screw drives, rack & pinion drives and even CAM drives.  Each mechanism offers advantages and disadvantages. Choosing the right technology can help increase load, speed, travel distance, or positioning accuracy.

Eliminate Motor Speed Fluctuations Caused By Input Voltage or Load Variance

Posted by Johann Tang on Jun 21, 2019 6:57:39 PM

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.

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.
