Master Class in αβγ (Clarke) and dq0 (Park) Transformations using Oscilloscopes
Join Teledyne LeCroy as we explain the principles and math behind simplifying a three-phase AC vector system into a simpler vector system for use by control systems and that can also highlight performance characteristics of the power conversion and control system.
Part 2: Advanced Transformations (dq0 Motor Rotor-reference Frame) and Application Examples
Date: Wednesday, January 14, 2026
Time: 11:00AM Pacific | 2:00PM Eastern
Duration: 60 minutes including Q&A
In part 2, we recap αβγ (Clarke) and dq0 (Park) transformation, introduce how a motor rotor operates in the presence of a three-phase AC electrical/magnetic field, discuss rotor-reference frame dq0 (Park) transformations and how that is used for near instantaneous rotor (motor shaft) speed and torque control. We’ll follow with various application examples for non-motor and motor applications. We’ll demonstrate the capability using an oscilloscope that is capturing signals and and calculating all of the quantities.
Topics to be covered in this webinar:
- Motor operation basics
- What signals or constants must be provided to calculate the rotor-reference frame dq0 transformation
- Vector Field-oriented Control (FOC) algorithms
- Why the dq0 transformation is not often used for AC induction motors
- Practical examples of the transformations performed using an oscilloscope
Who should attend? 3-phase power conversion control and systems engineers, especially for motor drives.
What will attendees learn? The fundamentals of three-phase vector transformations, why they are used and how the information they provide can optimize product performance.
