That being said there is a wide range of different motors and what you have on hand can be completely different. It is a type of polyphase system and is the most common method used by electrical grids worldwide to transfer power.
Therefore from wiring diagrams you already know the. Electric motors are electromechanical devices whose function is to transform electrical energy into mechanical energy through electromagnetic interactions. There are other engines generators that produce electricity by exploiting the mechanical energy such as alternators and dynamos. This symbol represents a 3 phase wound rotor motor.
When a motor s power supply is brought in from three wires instead of just one with the power delivery cycling through each of these in sequence hence the a part of ac it permits an effective power level that is 3 times higher about 1 728 times higher than a. Three phase electric power is a common method of alternating current electric power generation transmission and distribution. It is a type of 3 phase ac motor whose rotor is connected with external resistance through slip rings. A three wire three phase circuit is usually more economical than an equivalent two wire.
Wiring diagrams comprise a pair of things. Symbols that represent the constituents in the circuit and lines that represent the connections with shod and non shod. The advantage of wound rotor motor is that it generates high starting torque using less current. A three phase motor must be wired based on the diagram on the faceplate.

A three phase motor is more efficient than a single phase motor because of the peculiarities of alternating current ac. It is also used to power large motors and other heavy loads.
