A 5 kW split-phase motor running at 1750 rev/min is used to
drive a rotary pump, which operates 24 hours per day. An engineer
has specified a 200 mm small sheave, and 300 mm large sheave, and
B3000 belts. The service factor was 1.3. Analyze the drive and
estimate:
(a) center-to-center distance.
(b) suitable number of belts.
(c) F1, F2, Fc and Fi.
(d) the factor of safety.
(e) the belt life in passes

A motor apply power 10-hp split-phase motor speed at 1700 rpm is
used to drive a rotary pump, which operates 24 hours per day. An
engineer has specified a 7-in small sheave, an 10-in large sheave,
and three C112 belts. The service factor of 1.2 was augmented by
0.1 because of the continuous-duty requirement. Analyze the drive
and estimate the belt life in passes and hours.

The speed of a 11 KW, 150 V, 1300 rev/min separately excited
DC motor is controlled by a
single-phase fully-controlled thyristor converter. The rated
motor current is 25 A, and the
armature resistance is Ra = 0.5 Ohm. The ac supply is 160 V.
The motor voltage constant KE =
0.182 V/rev/min. Assume that sufficient inductance is present
in the armature circuit to make
the armature current continuous and ripple free.
For a firing angle of alpha = 20 degree...
