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

The differences between single-phase and three-phase AC induction motors don't stop with the input power supply.  There are a few things you need to know when using three-phase AC induction motors in an instantaneous forward/reverse operation.

There are three main types of stepper motors available in the market: PM (permanent magnet) type, VR (variable reluctance) type, and hybrid type.  What are the differences, which one should you use, and how do they work?

Proper grounding is necessary for electrical devices for different reasons, but why do we do it?

No matter how many functions a product offers, without an intuitive, easy-to-use software, those functions can be difficult to implement.

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?

STO, or "Safe Torque Off", is a dedicated, built-in safety circuit function that makes safety easier to manage for motion devices, such as an industrial robot.  It is part of the overall safety system designed to prevent injuries or damage.

Knowing how to use a product properly can make a huge difference in its performance and life.  For example, knowing how to maintain cast iron pans properly can make them last longer.  With electric motors, understanding the factors that affect motor life is the first step to extending life and decreasing costs in the long run.

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.

My first experience using DC motors was for a small elevator for a science project back in school.  Although I had no idea, that day would become only the first day of my experience with motors.

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?
