This document describes the features and characteristics of STMicroelectronics ST62 Family of microcontrollers in driving home appliance motor technology. It includes the three main motor families - Universal, Induction, and Electronically Commutated - as well as the relevant electronic control techniques made possible by the ST62 MCU. The ST62 MCUs, with their wide range of on-chip peripherals, wide supply voltage range, built-in ruggedness, and legendary noise immunity, enable low total system cost and advance electrical motor design. The document also describes basic electrical topologies and their associated power and signal electronics, exploring their strengths and weaknesses through practical examples to illustrate the advantages of electronic control using ST62 MCUs.
The document introduces the STMicroelectronics ST62 Family of microcontrollers as a solution for controlling electric motors in home appliances. It highlights the benefits of using these MCUs, such as low total system cost, wide supply voltage range, built-in ruggedness, and noise immunity.
The text details three main motor families used in domestic equipment: Universal (Brush), Induction (Brushless), and Electronically Commutated Brushless motors. It explores control techniques for each type, including Phase Angle Control and Chopper Control for Universal motors, and specific driver topologies like the ST6260 for Switched Reluctance Motors.
| MCU Drive Capability per Pin | 20 mA |
|---|---|
| Chopper Frequency Range | 5 - 20 kHz |
The three main families are Universal Motors, Induction Motors, and Electronically Commutated Brushless Motors.
The ST6260 microcontroller is offered as providing the simplest SRM driver.
