Asynchronous Motor Control using Atmel Evaluation Board
With AT90PWM3 microcontroller and Fairchild Smart Power Module
Controlling the speed of an asynchronous motor requires a three-phase frequency inverter. The ATAVRMC200 evaluation kit from Atmel is based around a flexible motor control board which uses a special AVR microcontroller, along with a Fairchild SPM for the output driver stage. A special feature of the system is that it can control asynchronous motors without using a sensor.
Anniversary Quiz
Answer these three questions correctly, and you could win a prize!
(a) Who developed the planar transistor at Fairchild in 1958? (Hint: he was Swiss by birth.)
(b) How many integrated components comprise an IGBT?
(c) What is the phase angle between any two of the three-phase outputs of a frequency inverter?
As prizes we are giving away ten ATAVRMC200 asynchronous motor controller evaluation kits, including asynchronous motors (see photographs), each worth well over £ 200!
Send your answers, by 21 May 2007, by e-mail to editor@elektor-electronics.co.uk or by post to Elektor Electronics, Regus Brentford, 1000 Great West Road, Brentford TW8 9HH, England, marking your envelope ‘Fairchild’. The editors’ decision is final.
