Electric motors are used to convert electrical, thermal, chemical or kinetic energy into mechanical energy. This allows you to power various types of vehicles, home appliances and even industrial machines, which is nowadays necessary for the proper functioning of many businesses. Three phase motors, which operate when connected to electricity with the appropriate voltage and frequency. A small box located outside the main part of the device protects the cables that run the machine after they are powered. The main parts of the engine are the stator and the rotor. In the first one, a magnetic field, also called rotating, is generated. It circulates at a speed equal to the applied voltage, and through contact with the rotor winding, together with short-circuit currents, it creates forces and torque that allow the engine to accelerate and simultaneously power the drive. This action makes the machine characterized by a high degree of safety. For this reason, it is perfect for industry. Currently, devices are made with much greater precision, so they are well protected against possible serious failures, such as phase failure, which in many cases could permanently damage the motor.
Three-phase motor – the energy-saving choice
Electric powering devices may seem expensive, but in industrial plants the use of this type of motors is extremely profitable. They can be used in various operating modes, and thanks to their simple structure, they can be modified and modernized. Three-phase motor with brake is the best choice for working with many types of machines. Stopping it is possible thanks to clamps or external voltage. This increases the safety of the person using the machine and additionally shortens the overrun time of its mechanisms. This type of motors are efficient devices that allow you to save on the daily use of powered equipment. Energy efficiency distinguishes the three-phase model from the single-phase model, which, although stable, requires much higher operating costs and possible repairs. It is worth increasing the thermal class of the purchased engine so that the permissible heating also increases. You can speed up this process by installing a fan. Thanks to these actions, the permissible switching frequency will additionally increase, i.e. how many times the engine can be turned on in an hour without overheating. This will have a positive impact on its work efficiency, which will further reduce operating costs.
Efficient three-phase motors with brake
Due to the achievable power and work efficiency, engines of this type are used mainly in workshops and industrial plants, where they power many individual devices with high requirements in terms of power or operating time. By adding or changing individual elements in the engine, such as the poles, it can be operated at increasingly higher rotational speeds. Three-phase motors are manufactured in accordance with generally applicable standards, which guarantee its highest possible efficiency. It affects not only the quality of work, but also slower wear of individual elements. For this reason, high-quality sheet metal is used to make them, as well as a larger amount of copper in the stator and rotor windings. Additionally, the bearings are better optimized, as is the geometry of the fans present in the engines. Another important feature is their low price, which in many cases can have a great impact on the purchase decision. These devices are characterized by high quality workmanship and a very simple design, so they do not pose a risk of serious failures and do not require frequent maintenance. Three-phase motors connected to the power grid with the appropriate voltage and frequency, they are essential elements of industrial drive systems.
