How to Use dq0 (Park) Transformations in Oscilloscopes for Rotor-reference Frame Motor Control Analysis

Join Teledyne LeCroy as we define and explain the math behind a dq0 (Park) transformation of a magnetically rotating three-phase power system into a stationary two-vector system referenced to the shaft of the motor. This makes it easy to understand the instantaneous impact of control system changes to the motor’s rotor speed and torque delivery and is the foundation of Vector Field-oriented Control (FOC) algorithms. A lesser transformation may also be used with any 3-phase power system. We’ll demonstrate the capability using an oscilloscope that is capturing and calculating all of the signals. In this webinar, we explain challenges and solutions for clocking, triggering, and timestamping in Giga-sample-per-second data acquisition systems.

Topics covered in this webinar: 

• • The difference between an αβγ (Clarke) and dq0 (Park) transformation
  • The mathematical derivation of the dq0 transformation
  • Why the dq0 transformation is not often used for AC induction motors
  • What signals or constants must be provided to calculation the dq0 transformation
  • Practical examples of the transformations performed on an oscilloscope

Who should attend? Motor control systems and motor drive engineers who need to provide high control to permanent-magnet motors, or any engineer working with three-phase power systems.

What attendees will learn? The fundamentals of dq0 transformations and why they are used.

Presenter: William Kaunds, Teledyne LeCroy Product Manager
