Answer / soumik kar

a two phase motor is a motor with the the starting winding and the running winding have a phase split.
e.g;ac servo motor.where the auxiliary winding and the control winding have a phase split of 90 degree.

Answer / ravindra paswan r

A single phase supply is connected to the motor but this 1
phase voltage does not create sutiable rotating torque in
the motor so, in the motor the winding is arrenged like a
way that the 1 phase voltage will split in to 2 phase and
this 2 phase voltage will provide rotating torque and this
type of motor is called 2 phase motor or split phase motor.

Answer / kumar

the motor which work between two phase is called 2 phase
motor.

Answer / rajesh

simply saying,
2 phase motor is that which consists of two wires input(1
phase and 1 neutral)

Why we use the D-curve MCBs in critical power distrubution.

Dear Friends, Need your help for connecting APFC panel, Quotation : I have 2 No’s 1000 KVA Transformers, both transformers are having separate APFC panels, ( Tr-1,400KVAR, TR-2,450 KVAR) Now I want to stop One transformer, present load is 650Amps, Max, So One transformer is enough, I have switched OFF TR-1, but PF is not maintaining properly, its 0.5, So now I want to connect TR-2 APFC also in TR-1 Loads, Can any one answer for my Quotation with drawing, how to connect TR-2 APFC panel in TR-1 Loads,
