Compared with what?
The definition of star connection is a connection of the ends of phase windings at the star point.
hahahaa
i think its use for 3 phase connection.
The term, 'star point', refers to the common point of connection for the three windings of a star-connected (wye-connected) transformer connection. The star point is usually earthed (grounded) and provides the neutral point of the connection.
Probably the reason is in the different voltages between the star and delta connection voltages. An electromagnetic brake designed for the lower voltage of the star connection would burn out or open when introduced to the higher voltage of the delta connection.
Because it is the same current, as you can determine by examining a circuit diagram of a star connection.

the speed decrease if increasing load..in star connection the speed lower
The power of a three-phase load is the sum of the three individual loads. It makes no difference whether they are connected in star (wye) or in delta.
Transmission circuits are prone to earth faults.Only star connection permits flow of earth fault current and the operation of earth fault relays.
In star each phase is 120 degree apart in delta angle between phases(R,Y,B) are 60 degree so star connection draw low current.
the connection here meant for the connection of windings in three core or limbs of a transformer. it might be delta or star connected.
