Welcome to Oriental Motor's "Engineering Notes" Blog:

Motors exhibit noise.  The important thing to know is how you distinguish normal noise from abnormal noise, and how to troubleshoot.

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 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?

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.

Besides load torque, acceleration torque, speed, and load inertia, overlooking certain sizing parameters during the motor sizing process can literally make or break your machine.

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

Stepper motors vibrate.  It's what they do.  To minimize motor vibration, first we need to understand where they come from.

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.  This post explains the unique technologies offered within the AlphaStep family of products and summarizes the numerous integrated options available.  It also can serve as a website navigation guide (video added).
