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.
