Star Delta Motor Terminal Box Connection

How to connect ac motor in delta star configuration 7 wiring materials asynchronous motor.

Star delta motor terminal box connection.

In this video we explain star delta connection in 3 phase motor terminal it is very important topic because we can easily make star delta starter but in mot. Star connection terminal motor. In delta connection the opposite ends of three coils are connected together in other words the end of each coil is connected with the starting. According to this standard the phases of motor windings are defined by w u v.

If our power supply is 200 vac 3 phase we need to connected the cooper bar terminal in delta position it mean a connection are u1 with w2 v1 with u2 and w1 with u2 it just need to follow. If our power supply is 200 vac 3 phase we need to connected the cooper bar terminal in delta position it mean a connection are u1 with w2 v1 with u2 and w1 with u2. Here i attached picture about motor terminal in star position. Asynchronous motor is an ac electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding.

It mean terminal cooper plate w2 u2 and v2 connect in one line here i attached picture about motor terminal in star position. For star delta stater the motor connection must have 6 cables from control panel and 6 terminals at induction motor u1 u2 v1 v2 w1 w3 to wiring the motor connection for star delta starter the important thing that we must fully understand is about the basic of star delta magic triangle. The windings of ac motors can either be connected in star y connection or in delta δ connection the standard that deals with this winding connection and designated marking of the terminal box is iec 60034 8. A normally close auxiliary contact from both star and delta contactors 5 6 are also placed opposite of both star and delta contactor coils these interlock contacts serves as safety switches to prevent simultaneous activation of both star and delta contactor coils so that one.
