Optimization of the start-up of an automated asynchronous electric drive
Incoming article date: 02.01.2026An asynchronous electric motor is the foundation of virtually every modern industrial machine. They are widely used in various industries and agriculture across the country. Starting electric drives for machines equipped with asynchronous motors poses a serious challenge for private workshop owners and farmers working in rural areas. This article presents a method for starting an asynchronous motor using a combination of a voltage multiplier and a frequency converter, ensuring the maintenance of the rated torque and full power of the electric drive. Using voltage multipliers to start industrial variable-frequency electric drives is an innovative solution that helps eliminate problems caused by low input voltage from the electrical grid. This is especially relevant when the actual grid voltage is below the minimum required value specified by the electrical equipment manufacturer
