what is the difference between ceiling fan and wall
mounteed fan technically
Answer Posted / vishal ingle
from the constructional point of view, it seems that
in ceiling fan the external body rotates with blades and
the center part is stationary (forms support).
and in wall mounted / table fan the external body i.e
stator is stationary (forms support) and the center part
i.e rotor rotates with blades

What is the reason of polyphase induction motor tripping suddenly on high current during running at 70% laod? Motor IR , winding resistance & inductance balance. Motor no load current is balance and ok as per mgfr. data.
would the same effect be achieved by reversing the connection to one winding of the induction motor 3-phase?

Graphs of measuring power and speed on dc motor
need to make a report. Need to choose a 3phase induction motor. Load conditions motor will operate in : Maximum Load: 30 Kw Speed: 2950 rpm Ambient temp: 20 cent Supply voltage: 440V Frequency: 50Hz need to look for the safety factor when choosing the motor, went through catalouge found a few, but dont know how to choose the safety factor allowing an extra load something above 30 KW to avoid any harm.
A 7 storey building has a floor area of 35,000sq.ft on each storey. On the ground floor 11KV electrical sub-station is to be erected. A load of 3kw for every 400sq.ft (p.f is 0.8) is proposed for each floor. fire pump 7.5hp, water pump 5hp, lift 2 nos, each 10hp and 20shop load of each shop is 5kw. calculate a. load each floor b. total load of building c. L.T feeders for aech floor and from transformer to main. d. distribution diagram e. capacity of sub-station/capacitor bank f. line diagram
