AIM:
To conduct the no load & blocked rotor test on 3- phase induction motor
& to draw the equivalent circuit of 3- phase squirrel cage induction motor.
FUSE RATING :-
125/100 * 7.5 A ≈ 10A
THEORY :-
A 3-phase induction motor consists of stator, rotor & other associated parts. In the stator
,a 3- phase winding (provided) are displaced in space by 120. A3- phase current is fed to the winding so that a resultant rotating magnetic flux is generated. The rotor starts rotat ....etc

AIM :
To conduct a direct load test on a 3-phase slip ring induction motor and to draw the performance characteristics.
FUSE RATING-
FOR- STATOR- 125% 0f 7.5A = 10A
FOR ROTOR – 125% of 11A = 15A
THEORY:
Slip ring induction motor is also called as phase wound motor. The motor is wound for as many poles as the no. of stator poles and always wound 3-Ф even while the stator is wound two-phase. The other three windings are brought out and connected to three insulated slip-rings mounted on t ....etc

AIM:
To determine the performance characteristic of a given single phase capacitor start induction motor by conducting load test.
FUSE RATING :
Fuse rating = 125% of rated current = 125/100 * 7.5
≈ 10A
THEORY:
The single phase induction motor is more or less a polyphase induction motor. The only
difference is that is given supply in single phase. This motor connect and motor function

AIM:
To draw the performance characteristics of 3-phase squirrel cage induction motor by conducting load test.
THEORY:
A 3-phase induction motor consists of stator and rotor with the other associated parts. In the stator, a 3-phase winding is provided. The windings of the three phase are displaced in space by 120º.A 3-phase current is fed to the 3-phase winding. These windings produce a resultant magnetic flux and it rotates in space like a solid magnetic poles being rotated magnetically.
