Fairchild Semiconductor's Design Tool for Motion-SPM™ Product Family Selection

Three-Phase Inverter Sine-Wave Modulation Support for Variable Speed Drive Applications

Designers of household electrical appliances such as washing machines, refrigerators, and air conditioners face the challenge of developing motor control solutions that reduce installation space and shorten electrical and mechanical design cycles while providing system efficiency and reliability for applications, all while meeting increasingly stringent energy guidelines and regulations such as ENERGY STAR® and European Commission Energy Using Products (EUPs).

To support designers in addressing these challenges, Fairchild Semiconductor has developed a motion control design tool that assists in selecting the optimal Fairchild Motion-SPM™ product family for specific applications. This tool supports three-phase inverter sine-wave modulation for variable speed drive applications that power permanent magnet synchronous motors (PMSM) and AC induction motors.

Product selection is based on detailed items of I/O information specific to each application. The design tool's output values include module component losses at motor/output frequency, junction temperature rise, thermal dissipation requirements, and junction temperature ripple.

The motion control design tool provides motor motion control designers with the following capabilities:

- A fast and accurate method to select Fairchild SPM® products suitable for the application

- Simulation means verifying worst-case design condition inputs and outputs in terms of losses and temperature rise

- Calculation of switching and conduction losses of power devices inside the module in specific applications, enabling designers to quickly consider virtual scenarios for optimal design

- Visual representation of losses, junction temperature rise, and allowable maximum temperature of internal components as a function of output phase current and switching frequency

- Total module losses and heat sink and cooling requirements

- PDF output support for simulation results conducted by designers

The motion control design tool is available on the Motion Control Tool Landing Page.
