Designers of home appliances – such as washers, refrigerators
and air conditioners – are faced with the challenge of developing
motor control solutions that meet stringent and evolving energy
guidelines and regulations, such as ENERGY STAR® and European
Commission Energy Using Products (EUPs), all while reducing
footprint, reducing electrical and mechanical design cycle,
bringing system efficiency and reliability to the application.

To help designers meet this challenge, Fairchild Semiconductor
(NYSE: FCS) developed the Motion Control Design Tool to assist in
the selection of the optimum Fairchild Motion-SPM™ device for their
specific applications. This tool addresses three-phase inverter
sinusoidal modulation for variable speed drive applications
powering permanent magnet synchronous motor (PMSM) and AC induction
motors.
Part selection is based on a detailed entry of application
specific I/O information. The program output includes module
component losses, junction temperature increases, cooling
requirements and junction temperature ripple at the motor/output
frequency.
The Motion Control Design Tool provides motor motion control
design engineers with:
- A quick and accurate method for
selecting the correct Fairchild SPM® device for their
application
- A simulation means for identifying
their design's worst case input and output conditions from a loss
and temperature rise aspect.
- A delineation of the module's power
component switching and conduction losses for their specific
application, enabling them to quickly consider "what if" scenarios
to optimize the design.
- Graphical presentation of internal
component losses, junction temperature rises and maximum allowable
case temperature as a function of output phase current and
switching frequency.
- Total module losses and
heatsink/cooling requirements.
- A PDF soft copy documentation of their
application analysis.
The Motion Control Design Tool can be launched from the motion
control tool landing page at:

A "Motion Control Design Tool PDF Help Guide" providing detailed
program input and output descriptions is provided through a link

Fairchild Semiconductor recently developed a new series of smart
power modules (SPM®), the SPM45H, that offers high system
efficiency while replacing up to 23 discrete components.
Designed with system reliability in mind, the SPM45H series
features the integration of 15 fully tested components compared to
23 discrete components, providing designers significant advantages
for 1.5kW motor designs. The SPM45H series provides system
efficiency, with built-in advanced NPT IGBTs, providing optimal
tradeoffs between conduction losses and switching losses, resulting
in higher power density. Advanced STEALTH™ FRDs provide a good
softness factor and low EMI characteristics.
Fairchild has a wide SPM package portfolio for driving highly
efficient inverter-based motors and enabling energy-efficient
designs. The Motion Control Design Tool complements and supports
all SPM devices in the portfolio by providing motion control design
engineers with an efficient means of calculating the power losses
and temperature rise in Fairchild Motion-SPM packages.
