Is There an Option Between Stepper Motors and Servo Motors?

Posted by Johann Tang on Aug 1, 2022 5:45:00 PM

Servo motor systems are expensive but great for demanding applications that require high speed, peak torque, or feedback.  Stepper motors are cost-effective but do not offer the peace of mind of feedback.  For designs that do not need the bells and whistles of servo motor systems, there is another option.

What is Modular Automation?

Posted by Johann Tang on Mar 16, 2022 7:04:08 PM

Modular automation is the next phase of factory automation where the same production line is separated into modules and can quickly reconfigure itself to serve different needs.  We're ready for this trend.  Are you?

3 Things to Know About the BLV Series Update

Posted by Johann Tang on Mar 15, 2021 12:00:00 PM

The BLV Series is one of two DC-input brushless motor speed control systems we offer.  While a brushless motor with hall-effect sensor feedback provides constant torque, wide speed range, and speed regulation, the BLV driver offers unique functions designed for mobile robots, such as low battery operation and ramp operation.

3-Axis Parallel Robot with AlphaStep Absolute Stepper Motors

Posted by Johann Tang on Oct 29, 2020 8:25:46 PM

Remember the days when we used to go to in-person events, such as trade shows?  Robot demos have always generated a lot of foot traffic in booths.  What's better to illustrate the synchronism of closed-loop stepper motors than 3 motors working together to create one specific motion?

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.

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 building a robot.

Improve Motor Performance With Redesigned Compact BLDC Drivers

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.
