From transmission error measurement to Pulley-Belt slip determination in serpentine belt drives: influence
Abstract —
Serpentine belt drives are often used in front
end accessory drive of automotive engine. The accessories
resistant torques are getting higher within new technological
innovations as stater-alternator, and belt transmissions
are always asked for higher capacity. Two kind of tensioners
are used to maintain minimum tension that insure power
transmission and minimize slip: dry friction or hydraulic
tensioners. An ....etc

ABSTRACT

In automotive mechanics, a Differential is an arrangement of gears that transmits power from the engine to a pair of driving wheels, dividing the force equally between them but permitting them to follow paths of different lengths, as when turning a corner or traversing an uneven road. The differential allows the driven wheels to rotate at the same speed while on a straight road; it allows the outer wheel to rotate faster (proportionately) than the inner wheel, while taking a curve or traveling ....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

SLIP FORMING.
INTRODUCTION:-
Civil engineering course put more attention to concrete and reinforcement while almost ignoring the major component like formwork. No attention is paid to economic design of formwork. Formwork costs approximately 10% of the total cost of the construction projects but at the same time sheltering/scaffolding involves major capital investment.
The construction industry tod ....etc

FUSE RATING:
(a)For Motor- 125% of rated current
= 125% of 17A=21.25A=25A
(b)For Alternator- 125% of rated current
=125% of 4A= 5A
THEORY:
In a salient pole alternator, the reactance of magnetic circuit along is along its quad stator axis. The alternator is driven by auxiliary prime mover at a speed slightly less than the synchronous speed under these conditions. The armature current is when the armature current mmf is in line with the field poles. The reactance by the magnetic field current is minim ....etc
