WEG ELECTRIC MOTORS ???? https://eletri.ca/WEG PROCOBRE INSTITUTE ???? https://eletri.ca/PROCOBRE What is motor closing? Motor closing is part of the connection of electric motors, the coils of a three-phase motor must be joined in a star connection or a delta connection, this allows the closing of a three-phase 220V motor or the closing of a three-phase 380V motor. The star-delta motor closing allows two voltages for the connection of a three-phase motor. The ends of the motor are the coils of electric motors, the motor connection with 6 points is the most common, but there are 12-point motors, 9-point motors and others according to the number of motor coils. How to test a motor coil? Motor coils are electrical resistances that provide an inductive effect creating electromagnets and the coil test is done with a multimeter. Among the objectives of this video, we highlight: What are the motor poles and how does the speed of a three-phase motor work? What are the possible coil closures in a three-phase motor? Topics covered: Many professionals in the world of electricity have heard about star and delta connections for electric motors, and these two topics have everything to do with the connection diagram of three-phase motors. To understand motor power supply, in fact the connection diagram of motor coils, we need to better understand how a three-phase motor stator works. In a motor, each coil creates two magnetic poles, a south pole and a north pole, and this happens in each of the phases. So a three-phase motor with 3 coils will have two poles per coil, and is called a two-pole motor. Three-phase motors can have 2, 4, 6, 8 or more poles, always in even numbers, depending on the number of coils wound. The number of poles in a motor and the electrical frequency of the network causes the motor speed to vary. The more poles, the slower the motor turns. The coil is attached to the stator inside the slots. There are motors that have stators with different numbers of slots, since motors can have different numbers of coils, precisely to have a configuration that allows for a different speed. The number of terminals on a motor indicates the connection possibilities for this motor. The most common are 6-lead motors and 12-lead motors. Any three-phase motor with 3 coils on the stator, that is, six terminals, offers the option of being able to work with two different voltages through different connections between the coils, which are star and delta connections. Creating a motor connection diagram is a constant activity for professionals in the world of electricity, which is why it is so important to better understand electric motors and their connections. Highlighted parts in this video (edit notes): 01:25 - To know how to close three-phase electric motors, it is important to know how a three-phase electric motor works, as well as its parts and characteristics. 02:12 - The number of poles is a characteristic for determining the rotation speed of a three-phase electric motor. 03:35 - Slip is important because it has to do with the rotation speed of an asynchronous electric motor. 05:20 - A three-phase induction motor can be connected to different voltages according to the closing of its coils.
