The video explains the direct startup method for a motor with an induction engine, which results in high startup currents. This can cause problems with the power supply or reduce the life of the engine. Other methods, such as the Arranque por Resistencia Primaria, aim to reduce the startup current.

• 00:00:00 The motor trifásico de inducción is one of the most commonly used industrial motors due to its simplicity in design and operation as well as its flexibility in various application areas. What sets this type of motor apart is the high current consumption during a direct startup, which has led to different solutions being developed for starting the engine without the need for a transitor. However, this solution depends on the application and economic factors, as some starting methods can be very expensive. Direct startup attention full is the simplest method for starting a motor with an induction engine, and the engine's exhausts connect directly to the electrical network via a simple conduction process. This application results in high startup currents between 4 and 8 times the nominal current, which can cause a power supply drop that affects the operation of other equipment in the environment or the electric grid. Direct startup also creates a thermal stress in the engine's valves with frequency, this startup reducing the engine's life by two thirds. Regulations limit the use of induction motors with direct startup that exceed a certain power output due to the startup problems that this approach presents. Other methods are used that aim to reduce startup current. One of the most commonly used is Arranque por Resistencia Primaria (AR), which uses a resistance
