Welcome to Zikouniversity - motor control theory and applied motor control for everyone
The idea behind ZikoUniversity was to create a place where we could include a lot more detail on certain subjects. The Motor Control FAQ section of the website has proved very popular but there are occasions in which many people need a bit more detail. We’ve included theoretical and background questions as well as more practical studies. Questions in this section tend to be somewhat more theoretical in nature, with the FAQ section being much more practically focused questions. As always, if you don’t feel we’ve answered your question and are looking for a bit more information then please just ask.
Motor Control Theory
Explore the theory and key principles behind brushless DC motor operation.
Fundamentally, the difference between sensored and sensorless brushless DC motors is simple. One has sensors and the other does not. However, there are a range of important implications of this simple difference which can have a significant impact on choosing the right option for your application.
There are a number of drive patterns for brushless DC motors including trapezoidal and sinusoidal.
Four (4) quadrant motor control enables complete control of the motor and is most commonly used in brushless DC and brushed DC motors.
No one brushless DC motor is necessarily like another.
Stepper motors are widely used in positional and low speed applications because of the high levels of accuracy they use.
Quick definitions of key terms that you may have seen but didn’t understand.
Motor Control in Practice
You may have seen us refer to optimising brushless DC motor controllers (especially sensorless brushless DC motor controllers).
There are a huge range of brushless ESCs on the market – many of which are incredibly low cost.
