A 4-Step Process for Testing Motor & Drives Systems
White Paper

Electric motors are electromechanical machines that convert electric energy into mechanical energy. Despite differences in size and type, all electric motors work in much the same way: an electric current flowing through a wire coil in a magnetic field creates a force that rotates the coil, thus creating torque. Understanding power generation, power loss and the different types of power measured can be intimidating This white paper gives an overview of basic electric and mechanical power measurements.

ScopeCorder | Yokogawa Test & Measurement

Overview:

The accuracy of a measurement instrument varies with the range over which a reading is measured. Not all instrument manufacturers specify accuracy and ranges in the same manner. This article explores the impact of range definitions on measurement accuracy and how one can be mindful when comparing accuracy across instruments.

Overview:

What is a Power Analyzer? Power analyzers and power meters measure electrical power in devices that generate, transform, or consume electricity.

Overview:

What is an Oscilloscope? Oscilloscopes, also called digital storage oscilloscopes (DSOs) or mixed signal oscilloscopes (MSOs), are common test instruments used to display, analyze, and troubleshoot electrical or physical signals.

Overview:

A ScopeCorder is a powerful portable data acquisition recorder that combines features of a multi-channel digital oscilloscope and a high-performance oscillographic recorder. As such, it can capture and analyze both short-term transient events and long-term trends for periods up to 200 days.

Overview:

In this application note you will learn when and how to use different methods to connect a current transformer to a power analyzer.

Overview:

With the increased demand in electric-hybrid vehicles, the electromechanical designs of in-vehicle systems are becoming more sophisticated and there has been a demand shift towards high efficiency brushless direct current motor (BLDC) implementation. Think of motorized seat adjustment, electric window, power steering, HVAC fans, pumps, etc. In many of these systems various types of motors are used as actuators; more specifically, 3-phase BLDC motors are gaining popularity as they provide these important advantages:

  • Improved speed vs torque characteristics
  • High dynamic response
  • High efficiency
  • Extended speed ranges
  • Long operation life
Overview:

How can I capture data from motion sensors synchronized with other analog data? The Yokogawa ScopeCorder series of instruments feature input modules and functions to make this possible. 

Overview:

How to use built-in calculations to analyze motor rotor position and find the relative angle between the rotor and sensors such as encoders or resolvers.

Overview:

Government agencies that define the standardization of energy efficiency metrics continue to be a driving force behind the development of the next generation electric vehicle powertrains. These metrics require manufacturers to have high confidence in their measurements and motivate the optimization of efficiency.

Overview:

This white paper discusses the basics of AC, DC, and power measurements, and a three-step process for making precision electrical and mechanical power measurements on a variety of motors and variable frequency drive (VFD) systems. It is also shown how these measurements are used to calculate the energy efficiency for motor and drive systems. 

Overview:

Understanding motor power consumption and measuring efficiency is key to optimizing motor development and usage. This eBook discusses the basics of power measurements of motor systems, including the drive system, while also looking at mechanical measurements.
