With the combination of the carefully designed torque,
speed and direction control circuit, it can form a better motor
driver for solar tracking system. This motor driver circuit is
builded based on the idea to control the cost as low as
possible. Therefore, the list of components used is simple and
easy to be found in the market. Although the cost is low, the
resultant driver delivers excellent capability of controling the
speed and torque in a linear manner. The driver managed to
control the current and the voltage of the output at the same
time and therefore it can controls the resultant power transfer
to the motor. The motor is only consumes maximum of
0.05A when it is idle. This stable and easy control definitely
will shorten the development period for engineers to design
the solar tracking system.
