Motors & Drives

Yokogawa has long been recognized as an industry standard for Motors & Drives. Yokogawa power analyzers built their reputation by providing accurate and reliable measures of speed, torque, motor output / mechanical power, synchronous speed, slip, motor efficiency, total efficiency, and many other parameters related to motor evaluation and design.

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.
