Motor Sizing Basics Part 2: Load Inertia

Posted by Johann Tang on Jan 17, 2020 7:51:53 PM

Other than torque or speed, another factor should be considered when sizing motors.

Motor Sizing Basics Part 1: Load Torque

Posted by Johann Tang on Jan 14, 2020 8:14:54 PM

Proper sizing of a motor requires that 3 criteria must be met: torque, load inertia, and speed.  For the first part of this Motor Sizing Basics series, I will be explaining what load torque is, how to calculate it for specific application examples, and how it fits into the torque requirement for the application.

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.

Improve Motor Performance With Redesigned Compact BLDC Drivers (VIDEO)

Posted by Johann Tang on Jun 3, 2019 5:33:13 PM

The BLH Series compact BLDC motors and drivers have been around for a long time, and there is a good reason.  Customers seem to favor the combination of a highly efficient, compact motor and a light weight board type driver that is easy to use.  Having a high torque, flat style hollow shaft gearhead as an option also helps in increasing torque as well as minimizing footprint.

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.

Introduction to MEXE02 Support Software (VIDEO)

Posted by Johann Tang on Mar 12, 2019 7:30:00 AM

The MEXE02 support software is a universal motion control and monitor software used with many products from Oriental Motor, such as the stepper motor drivers from AZ Series, AR Series, and RK2 Series, or brushless DC motor drivers from BLE2 Series and BX2 Series.  This post is useful for first-time users to gain a quick understanding of the software and what it can do.

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.

Improve Gripping Operation with Multiple Torque Limit Settings (VIDEO)

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

Robotic grippers are typically used to grip parts for transport.  The driving force behind a gripper can be pneumatic, hydraulic, or electric.  Which type is best for gripping?
