the ATAVRMC100 is an evaluation kit dedicated to brushless dc motor control, for both hall effect sensor control and sensorless control using back electromotive force. the kit includes an evaluation board, a 3-phase bldc motor and a demon- stration software. it allows users to quickly evaluate the capability of the avr ? microcontroller at90pwm3b to control high speed brushless dc motor applications. the kit can also serve as a devel- opment platform. low cost avr development tools make debugging easier, and source codes, written in c, can be easily re-used by developers for their own motor control applications. key features o evaluation board with at90pwm3b microcontroller o 3-phase bldc motor o for both hall sensor and sensorless applications o supports in-system programming and chip emulation o cd-roms with datasheets, application notes and demonstration software applications o air conditioning (hvac) o refrigerators, fans, pumps o high tech industrial constant speed applications o traction elevator o medical equipment m icrocontrollers evaluation kit ATAVRMC100 e valuate and d esign b rushless dc m otors a pplications motor control
bldc m otor c ontrol e valuation k it ATAVRMC100 the ATAVRMC100 bldc motor control kit is an evaluation tool and development board for the at90pwm3b avr microcontroller from atmel. the board includes power bridges for bldc motors and can realize zero crossing voltage detection, hardware overcurrent detection and motor supply voltage measurement. an on board lin transceiv- er allows to drive application through a lin network. programming of the code into the microcontroller's flash memory can be performed with an avrisp or a jtagice mkii through the dedicated con- nectors. power bridge for bldc motors o any commutation schemes are possible. o recommended voltage operation from 8 to 16v dc (4a) ordering information o ATAVRMC100 the latest version of all softwares is available free of charge on atmel web site: www.atmel.com product features o on board at90pwm3b microcontroller in so32 package (2.7-5.5v) o hall sensor or sensorless configuration o zero crossing voltage detection o hardware overcurrent detection o motor supply voltage and operating current measurement o system clock: internal rc oscillator o on board lin transceiver atmel ata6661 o expansion connector to be used with other avr microcontrollers o many access points for test and debug o dimension: 75 mm x 55 mm bldc motor for a comprehensive and ready-to-use evalua- tion, a 3-phase bldc motor is provided. o manufacturer: t ecmotion o hall sensors included. also usable as sensor- less motor. o phases: 3 ? poles: 8 o voltage: 12v o speed: 6200 rpm o peak torque: 0.19 n.m support all design hints are described. any new design can use these examples as a starting point. o ATAVRMC100 user manual o hardware schematics and layout o self tutorials o application notes and software examples development tools only low cost standard avr tools are required for application development and debug. o avr studio ? software interface o isp connector for on-chip in system programming o isp connector for debug wire disclaimer: the information in this document is provided in connection with atmel products. no license, express or implied, by estoppel or otherwise, to any intellectual property right is granted by this document or in connection with the sale of atmel products. except as set forth in atmel?s terms and condi- tions of sales located on atmel?s web site, atmel assumes no liability whatsoever and disclaims any express, implied or statutory warranty relating to its products including, but not limited to, the implied warranty of merchantability, fitness for a particular purpose, or non-infringement. in no event shall atmel be liable for any direct, indirect, consequential, punitive, special or incidental dammages (including, without limitation, damages for loss and profits, business interruption, or loss of information) arising out of the use or inability to use this document, even if atmel has been advised of the possibility of such damages. atmel makes no representations or warranties with respect to the accuracy or completeness of the contents of this document and reserves the right to make changes to specifications and products descriptions at any time without notice. atmel does not make any commitment to update the information contained herein. unless specifically provided otherwise, atmel products are not suitable for, and shall not be used in, automotive applications. atmel?s products are not intended, authorized, or warranted for use as components in applica- tions intended to support or sustain life. ? atmel corporation, 2007. all rights reserved. atmel ? , logo and combinations thereof, ?everywhere you are ? ?, avr ? and oth- ers are registered trademarks or trademarks of atmel corporation or its subsidiaries. other terms and product names may be the trade- marks of others. 4094b-avr-12/07/ headquarters atmel corporation 2325 orchard parkway san jose, ca 95131 usa tel: (1) 408 441-0311 fax: (1) 408 487-2600 international atmel asia room 1219 chinachem golden plaza 77 mody road tsimshatsui east kowloon hong kong tel: (852) 2721-9778 fax: (852) 2722-1369 atmel europe le krebs 8, rue jean-pierre timbaud bp 309 - 78054 st quentin-en- yvelines cedex france tel: (33) 1-30-60-70-00 fax: (33) 1-30-60-71-11 atmel japan 9f, tonetsu shinkawa bldg. 1-24-8 shinkawa chuo-ku, tokyo 104-0033 japan tel.: (81) 3-3523-3551 fax: (81) 3-3523-7581 literature requests www.atmel.com/literature web site www.atmel.com
