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?

Gear Basics: Backlash vs Lost Motion

Posted by Johann Tang on Apr 29, 2020 9:13:21 PM

The significance of position control accuracy of motors varies depending on the application.  For an AGV in a farm with DC motor-driven wheels, position control accuracy is probably not as crucial as a surgical robot where incisions are controlled by servo motors or stepper motors.

The Power of the AlphaStep Family

Posted by Johann Tang on Aug 28, 2019 2:37:43 PM

AlphaStep Logo

The word, "AlphaStep", describes Oriental Motor's patented Hybrid Control technology, which offers improved stepper motor performance by sensing the rotor position and automatically switching between open-loop and closed-loop operation when necessary.  First introduced in 1998 as the AS Series, the Alphastep Hybrid Control technology ushered in a new age where stepper motors can emulate servo performance at a lower cost.  Over the years, we improved the AlphaStep Hybrid Control technology with 2 major advancements to close the gap between stepper motors and servo motors even further.

This post explains the unique technologies offered within the AlphaStep family of products then summarizes the numerous integrated options available.  It also serves as a website navigation guide.

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.

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.
