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 introduces another option.
Welcome to Oriental Motor's "Engineering Notes" Blog:

The differences in 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 type, VR type, and hybrid type. What are their differences, and which one should you use?
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 a robot. It is part of the overall safety system.
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.
I will never forget my first engineering project involving motors. I built a small elevator for a science class back in elementary school. Of course, it worked great during the testing phase, but it failed to perform when it counted.
