![]() ![]() This project can be implemented in dense populated areas like railway station, bus stands etc where more amount of vibration energy will be obtained. It is designed to accept step pulses at up to 25,000 per second. In order to supply power to the load an inverter circuit is required by which the generated voltage is fed to the CFL lamp load. This Stepper motor controller uses the L297 and L298N driver combination it can be used as stand alone or controlled by microcontroller. ![]() The use of boost converter is to increase the level of voltage ranges about 12V and is stored in a 12V battery. It is a dual-channel H bridge motor driver which can be easily used to drive one single stepper motor. In order to increase the voltage, the boost converter circuit is used. The L298N Motor driver IC is powerfully built with a big heat sink. The produced electrical energy from the piezoelectric crystal is very low in the order of 2-3volts and is initially stored in a 2v rechargeable battery through a charge controller ,since it is not possible to charge a 12V battery through crystal output. These materials have the ability to absorb mechanical energy from their surroundings, usually ambient vibration, and transform it into electrical energy that can be used to power other devices. Piezoelectric materials have a crystalline structure that they can convert vibrations into electrical energy and is vice-versa. There are two H bridges and can be used in many areas. The L298 is the H-bridge motor drive integration. The use of piezoelectric crystal is to generate electric output from surrounding vibrations. Thanks to these two integrated stepper motors The L297 is a step motor control integral, which generates the phase signals of the step motor at the output via the control and clock signals applied to the input. #Stepper motor driver using l297 and l298 ic generator#An on-board step pulse generator can be used if desired (40-650 pps range).
