The electric motor that has six terminals or in the popular way known as electric 6-prong motor is an electric AC motor because it is a most popular electric machine in the industrial application as it is an excellent converter of electrical energy in mechanical energy.
The emergence of this electric motor took place in the hands of Nicola Tesla and the technological advance allows us to have today’s electric motor to be applied and industrial follow-ups.
Based on this principle, the three-phase induction electric motor on the winding closure types of the six-conductor three-phase electric motor with six-prong motor. It is necessary that the electric motor provides the option of six terminals to allow power through two different levels, for example 220V and 380v. Therefore, these two types of closure for this type of electric motor are: closing in triangle and closing in star.
In the vast majority, the electric motor has six cable ends in its junction box. The closing of this electric motor is done in a triangle and provides the closure at the lowest voltage that it is able to withstand. https://www.mrosupply.com/lighting/lighting-fixtures/vaporproof-fixtures/1432758_vxbrled26dg_rab-lighting/
