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.

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
OAny commutation schemes are possible.
ORecommended Voltage Operation from 8 to
16V DC (4A)
