By Shannon Given, Program Manager, Motor & Drive Systems 2018
Every year the Motor & Drive Systems conference evolves to address the changes in the industry. We want to make sure that the sessions stay relevant to meet the needs of our attendees. For the first time, the 2018 event will feature a dedicated track on motor testing and simulation. Each session will delve into issues such as proactively improving motor performance and efficiency, power quality and the identifying potential issues before they become a problem.
Here is a quick look at some of the sessions in the Motor Test & Simulation track:
Rapid Efficiency Mapping & Motor Analysis
The characterization of electric motors has recently become an important topic in many engineering labs throughout the world especially for electric and hybrid vehicles. To test and characterize electric motors, many labs have put together systems with multiple pieces of measurement equipment from different suppliers. While these systems work, they often have high levels of complexity and operate much slower than an optimized system. This presentation offers a revolutionary measurement solution specifically designed for electric motor testing which consolidates many systems into one, allowing for rapid efficiency mapping, reliable motor analysis and considerably boosts productivity, capability plus research and development.

Practical Considerations for Torque Testing of Electric Motors
Torque of an electric motor is of utmost important to manufacturers and users. The approach followed to determine torque depends on the type of motor and the type of torque (rated, locked-rotor, peak or breakdown). The different approaches applied for induction motors and permanent magnet motors are equally challenging and their effectiveness is dependent on instrumentation issues, scaling inaccuracies, temperature effects and non-linear phenomena. This presentation will discuss the torque requirements of induction and permanent magnet motors, focusing on the challenges of testing for these parameters. The presentation puts forward practical techniques and considerations for torque testing of induction and permanent magnet motors.

Control Technologies for High Frequency AC Motors and Generators
To meet competitive industrial demands, motor and control technologies are advancing at a significantly fast rate, from replacement contact kits that last longer to motors with even better specs, it’s all getting better. Recently, demand for high frequency AC motors and generators(mainly PM brushless and Induction motors) are increasing and it is a big challenge for power electronics and motor control. In this presentation, we will discuss on technical limitations on current drives on high frequency operation and several techniques to overcome these limitations, including motor control algorithms (FOC and DTC), various phase delays at high frequency operation, and switching characteristics of power semiconductor switches. Result from simulation as well as test result from actual drive system will be presented.

Fast and Precise Measurements of Magnetic Rotor Systems: Quality Control for Efficient Engines
Accelerated by enhancements of electric mobility, testing of electric motors has become of increasing importance in the automotive industry. Due to inhomogeneous magnetic fields an inaccurate PM rotor makes an electric motor inefficient and reduces the engine power directly. Matesy has developed a new rotor measuring station based on 3-axis Hall-sensors for 3D field measurement, magneto-optical sensor module for fast and high-resolution field visualization and a distance sensor for simultaneous geometry measurement. With its smaller dimensions it is suited for various rotor sizes and flexible use in both laboratory and production environment for the intended 100 percent control of PM rotors./

Predictive Maintenance Through Electrical Testing and Motor Diagnostics
This presentation will focus on electrical predictive maintenance test methods for motors utilizing both static and dynamic testing technology. It will begin by discussing motor materials, failure modes, reasons for material failure and specific tests/parameters used to detect motor problems prior to failure, avoiding costly down time. It will conclude with confirming case studies and benefits.

The Importance of Thermal Protection For Torque Motors
In order for a direct drive motor to be able to properly operate through the lifetime of a machine, it must have its temperature properly monitored to avoid any unwanted overheating and damages which would be unrepairable. There are multiple methods used to do so both on a controller level and a sensor level, and understanding how each come into play can help mitigate their weaknesses. This presentation will go over these methods to help a user better understand how they work and avoid motor overheating long term.
