Design, Modeling and Control of a Super High-Speed Permanent Magnet Synchronous Motor
Super high speed motors can achieve very high power output with very small size and weight compared to conventional machines. This presentation demonstrates the design process of a two-pole, 24-slots super high speed PMSM motor. The rated speed of the motor is 150 krpm and the rated output power is 3 kilowatts. The motor is designed to meet the high speed range of operation, with special considerations in rotor structure, winding and permanent magnet shape. The FEA simulation verifies the performance of the motor, with the efficiency higher than 93 percent at designed speed. Sensorless control scheme to drive the machine is also presented.

Off Grid Mission Focused Electric Motion
As engine driven hydraulic and pneumatic applications migrate to electric motion, the concept of designing the entire system to meet mission requirements becomes important. Using recent developments in 1 kw to 10 kw power conversion, it is now possible to design the motion system to the optimum operating voltage for the application and select the power source to support the mission energy requirement, even if that source is a different or varying voltage source. This presentation will explore the concept of off grid mission focused electric motion using examples from commerce, industry and agriculture.

Verifying Integrated Motor, Drive and Control Systems With an Integrated Toolset
Domain-specific design and test of integrated systems involving motors, electronics and control software is no longer feasible. Effective design of complex integrated systems requires a modeling and simulation environment that integrates multiple domain-specific development tools, because waiting until a physical prototype is available to verify overall performance puts the whole program at unnecessary risk. This presentation introduces a development environment that supports progressive refinement of system models, from abstract to high-fidelity. It demonstrates virtual integration of BLDC and/or induction machines, digital, analog and power electronics, and plant mechanical dynamics. This integrated environment alongside a progressive refinement approach helps engineers gain confidence in a design before committing to a specific implementation, thus reducing overall program risk.

Practical sensorless techniques are now applied in diverse applications, including fans and pumps, compressors, appliances and commercial machines. Sensorless algorithms, tuning methods and application examples will be discussed. Due to higher power density, high speed machines are getting popular, we will discuss design requirements and control techniques to drive high speed (frequency) motors. We will also discuss drive technologies applied in three-phase active power supplies (boost rectifier) that meet the industrial needs of reliable DC sources and power factor concerns.

Protecting PCBs from Damage Caused by Failed PowerFETS
Industrial controllers, motors and electronic components can benefit from the application of robust, reliable circuit protection that helps prevent damage caused by thermal runaway of power FETs and other failed power components. Power FETs help provide the precise power delivery that is often needed in critical operations found in manufacturing, automotive and medical applications. However, Power FETs can also present a potential risk in the end application; if the FET experiences a short circuit it may overheat, resulting in fire damage to the PCB. This presentation examines common methods for protecting the PCB from overheating and fire damage through the use of thermal protection devices.

DIP-IPMs for Small Motor Drive Applications: Moving Towards Standard Packages and Features
The transfer molded DIP-IPM was first introduced by Mitsubishi Electric in 1998 to address the rapidly growing demand for cost effective motor control in consumer appliance applications. Over the years continuous improvements in package thermal performance, power chip design, and HVIC (high voltage integrated circuit) technology has enabled the development of a complete line of modules for motors rated from about 100 W to more than 15 KW at line voltages of 100 VAC to 480 VAC. Unfortunately, the piecemeal evolution of these modules resulted in an array of completely unique packages with inconsistent feature sets. This presentation will describe the latest effort to standardize the packages and features across all power ranges. Three standard package outlines with uniform features will be presented. The common integrated features include level shifting HVIC based gate drive, over current protection, under voltage lock-out, temperature measurement with feedback signal and boot strap diodes.
