Students can create basic automation programs and gradually move toward more advanced industrial control applications.
Motor control is an important area of both power engineering and industrial automation. Motor control laboratory equipment helps students understand different methods of starting, stopping, reversing, and controlling electric motors.
Common training equipment includes direct-on-line starters, star-delta starters, contactor control systems, overload relays, motor protection devices, and control panels.
These practical exercises help students understand how motors are safely operated in industrial environments.
5. Variable Frequency Drives
Variable Frequency Drives, or VFDs, are commonly used to control the speed and performance of AC motors. VFD training equipment allows students to explore the relationship between motor speed, frequency, voltage, and load.
A VFD laboratory setup can be used to demonstrate:
- Motor speed control
- Frequency adjustment
- Acceleration and deceleration
