When you use Yokogawa instruments, you’re partnering with the leader in power analysis. This means spending less time on second-guessing the quality of your measurements and focusing more on moving your project forward. Yokogawa provides tools to help you analyze the “electro” and “mechanical” challenges of electromechanical systems. Gain valuable insight into the full source-to-load system from the supplied power to motor output - and everything in between.
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.
Standards driving energy efficiency classifications are a driving force behind the development of the next generation of motor and drive technologies. These classifications drive manufacturers to maximize efficiency, requiring a high confidence in energy measurements.
Various measurements at tests points on the motor and drive system require specialized equipment optimized to ensure the highest quality with few trade-offs. The correct instrument may depend on the level of accuracy, number of channels, or type of signal being acquired.
In this application note you will learn when and how to use different methods to connect a current transformer to a power analyzer.
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:
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.
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.
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.
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.
