Mootorijuhtimist refers to the control of electric motors. This encompasses a wide range of techniques and technologies used to start, stop, and regulate the speed and torque of electric motors. The primary goal of motor management is to ensure efficient and reliable operation of machinery powered by these motors, while also protecting the motor itself from damage.

Various methods are employed for motor management depending on the type of motor and the application's requirements. For direct current (DC) motors, simple resistance control or more sophisticated electronic controllers can be used to adjust speed. For alternating current (AC) motors, particularly induction motors which are widely used, management strategies are more complex. These include direct-on-line starting, star-delta starting, and the use of soft starters or variable frequency drives (VFDs).

Soft starters gradually increase the voltage applied to the motor during startup, reducing mechanical stress and electrical inrush current. Variable frequency drives (VFDs), also known as inverters, offer the most advanced level of control. They can precisely adjust the motor's speed and torque by varying the frequency and voltage of the power supplied to it. This leads to significant energy savings, improved process control, and extended equipment life.

Modern motor management systems often integrate protection features such as overload, short circuit, and phase loss protection. These safeguards are crucial for preventing motor burnout and ensuring operational safety. The selection of an appropriate motor management strategy is critical for optimizing performance, minimizing energy consumption, and ensuring the longevity of electric motor-driven systems across various industries.
