What are electric drives?




Before we dive into the book, let's first understand what electric drives are. Electric drives are systems that control the speed, torque, direction, and position of electric motors. Electric motors are devices that convert electrical energy into mechanical energy, and they are used in various applications such as industrial machines, vehicles, robots, appliances, etc. Electric drives consist of three main components: a power source (such as a battery or a generator), a power converter (such as an inverter or a rectifier), and a controller (such as a microprocessor or a PLC). The power source provides the electrical energy to the motor, the power converter converts the electrical energy into the appropriate form for the motor, and the controller regulates the power converter according to the desired output.


Why are electric drives important?




Electric drives are important because they enable us to control electric motors efficiently and precisely. Electric motors have many advantages over other types of motors, such as high efficiency, low maintenance, high reliability, low noise, high power density, etc. However, electric motors also have some drawbacks, such as variable speed, variable torque, variable direction, etc. These drawbacks can be overcome by using electric drives that can adjust the motor parameters according to the load requirements and operating conditions. Electric drives can also improve the performance, safety, and quality of electric motor applications by providing features such as speed control, torque control, position control, braking, reversing, protection, etc.


What are the benefits of electric drives?




Electric drives have many benefits for both users and society. Some of these benefits are:


  • Energy saving: Electric drives can reduce the energy consumption of electric motors by optimizing their operation and minimizing their losses.



  • Cost saving: Electric drives can reduce the operating and maintenance costs of electric motors by extending their lifespan and reducing their wear and tear.



  • Environment friendly: Electric drives can reduce the environmental impact of electric motors by reducing their emissions and noise.



  • Productivity improvement: Electric drives can improve the productivity of electric motor applications by increasing their speed, accuracy, flexibility, and quality.



  • User convenience: Electric drives can enhance the user convenience of electric motor applications by providing easy operation, remote control, feedback display, etc.
