Description
The Stellaris® Alternating Current Induction Motor Control Module (MDL-ACIM) is a rapid-time-to-market module solution that offers OEMs the capability of quickly adding AC induction motion control capability to any application. Combining the strength and flexibility of Luminary Micro's Stellaris microcontrollers with Fairchild Semiconductor's power modules creates an advanced ACIM motor control solution that has been carefully engineered for performance, cost, and flexibility. AC induction motors are particularly suited for use in major home appliances and white goods (refrigerators, dishwashers, washing machines, and dryers), residential and light commercial HVAC systems, and three-phase industrial motor drives.
Features
The MDL-ACIM contains Luminary Micro’s new feature-rich Stellaris LM3S818 microcontroller designed for motion control applications and Fairchild Semiconductor’s FSBS10CH60 power module. The MDL-ACIM takes advantage of the integrated features of the Stellaris microcontroller and the processing power of the ARM® Cortex™-M3 core to implement energy-efficient, space vector modulation control.
The MDL-ACIM includes the following product features:
- Advanced motor control for three-phase and single-phase AC induction motors
- Accelerated integration process through a flexible platform
- Dynamic braking circuit
- Active in-rush control circuit
- Easily change line filter, bus capacitors, and JTAG interface
- Includes code for main control algorithms including space-vector modulation and sine control
- Accurate current sensing using split low-side current sensing
- Several isolated control input options including:
- Virtual COM port through integrated USB port
- Logic-level serial port
- Speed potentiometer and mode switch
- Speed and position monitoring using quadrature encoder/tachometer input
- Electrically isolated JTAG port for software debugging
- Bootloader for firmware upgrades over serial port
