Motor converts the electricity to mechanical work.
Pump is a device to force a gas or liquid to move in a
particular direction

Answer / alianwar

MOTOR : An electric motor uses electrical energy to produce
mechanical energy, usually through the interaction of
magnetic fields and current-carrying conductors. The
reverse process, producing electrical energy from
mechanical energy.
PUMP : A pump is a device used to move fluids, such as
gases, liquids or slurries. A pump displaces a volume by
physical or mechanical action. One common misconception
about pumps is the thought that they create pressure. Pumps
alone do not create pressure; they only displace fluid,
causing a flow. Adding resistance to flow causes pressure.
Pumps fall into five major groups: direct lift,
displacement, velocity, buoyancy and gravity pumps

HELLO EVERYONE, I RECENTLY HAVE FOUND ONE PROBLEM, I WAS TAKING NO LOAD TRIAL OF AN HT MOTOR 920 MOTOR , 1440 RPM , 6.6 KV, WITH AUTO TRANSFORMER. AT 450 V, LOAD WAS 40 AMP AND SPEED WAS 250 RPM. BUT AS WE INCREASE VOLTAGE FROM 450 TO 480V, LOAD BECOME 41 AND SPEED REDUCED TO SOME RPM . SO WHICH PHENOMENON ACTED HERE FOR REDUCING SPEED.?? AND IS IT HAPPENING ALWAYS OR IT IS RARE? I ALSO HAVE FACED SUCH PROBLEM WITH FEW LT MOTOR ALSO.
