Motor Selection Basics: Types of Electric Motors

Posted by Johann Tang on Sep 30, 2021 9:19:49 PM

Which type of electric motor do you size for your conveyor, XYZ table, or robot?  Before you select one, you must understand the characteristics of each type of motor in the market.

Motion Programming Example: Timed Pressing Operation

Posted by Johann Tang on Apr 29, 2021 4:47:13 PM

In this blog post, I will explain how to easily program a timed pressing operation with our MEXE02 universal product support software.  This example works for any products included in the AlphaStep AZ Series family, which also includes other series that use the same technology and software.

Speed Control Basics: VFD or Triac for AC Induction Motors?

Posted by Johann Tang on Feb 26, 2021 9:09:03 PM

When a voltage is applied to an AC induction motor, it runs at a certain speed.  Variable speed requirements for AC induction motors are typically fulfilled by a 3-phase motor and an inverter or VFD.  This blog post also introduces another option.

Wiring Basics: Unipolar vs Bipolar

Posted by Johann Tang on Aug 28, 2020 9:03:36 PM

An easy way to alter the speed and torque characteristics of a stepper motor is to connect it to a different type of driver or change its wiring configuration.  However, there's more to it.  Knowing the pros and cons between "unipolar" and "bipolar" can make or break your stepper motor performance.

Control Basics: The Difference Between Sink and Source Logic

Posted by Johann Tang on Apr 30, 2020 9:16:14 PM

For someone who has never had experience wiring I/O for motion control, it can be scary the first time.  If devices are not wired correctly, it can cause a range of issues from a motor simply not doing what's expected to irreversible product damage.  I still get that nervous feeling before I press the START button on a demo.  Murphy's Law, anyone?

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.
