Electric Motor Testing Seminar October 8, 2009

The one hour seminar will cover making precision electrical power measurements on AC motors and variable speed drives.

Topics will include:

• Efficiency measurements of the drive
• Motor and complete system
• Accurate measurements of the fundamental PWM voltage of a drive
• Phase voltage measurements without a neutral line
• Other testing techniques outlined in IEEE Standard 112B, Test Procedure for Polyphase Induction Motors.
