hey everyone let's discuss something
0:02
important voltage drop and how it
0:04
affects electric motors it might sound
0:06
technical but trust me it's simple once
0:09
you understand it so what happens when
0:11
the voltage drops well the first thing
0:13
to understand is that Motors need a
0:15
certain voltage to generate torque the
0:17
force that keeps them running if the
0:19
voltage drops the torque drops even more
0:21
because torque is roughly proportional
0:23
to the square of the voltage for example
0:26
if voltage drops by just 10% the torque
0:28
can drop by almost 19% that's a huge
0:31
difference now does this affect all
0:34
Motors the same way not really it
0:36
depends on the load let's take lightly
0:38
loaded Motors like the ones in air fans
0:41
a slight voltage drop won't hurt much
0:44
the fan might slow down a little but
0:46
won't draw excessive current or overheat
0:48
so in this case the impact is small but
0:51
what if the motor is heavily loaded like
0:53
in an air compressor now we've got a
0:55
problem a voltage drop here can cause
0:57
the motor to struggle overheat or even
1:00
trip the breaker why because when the
1:02
voltage drops the motor compensates by
1:04
drawing more current and too much
1:06
current means overheating insulation
1:08
damage and even motor failure over time
1:11
now here's the worst case scenario if
1:13
the protection device fails to open the
1:15
circuit the excessive current can burn
1:17
the motor windings that means complete
1:19
motor failure instead of just
1:21
overheating the windings could melt or
1:23
burn leading to costly repairs or even
1:25
the need for full replacement and here's
1:28
another issue if the voltage keep keeps
1:30
fluctuating Motors running under heavy
1:31
loads can become less efficient require
1:34
more maintenance and have a shorter
1:35
lifespan that's why voltage drop isn't
1:38
just a minor inconvenience it's
1:40
something that can seriously impact
1:41
performance and costs so what can we do
1:44
to avoid these problems here are a few
1:47
quick tips use properly sized cables to
1:49
reduce resistance and minimize voltage
1:52
drop check your voltage levels regularly
1:54
don't wait until the motor overheats use
1:57
voltage stabilizers or automatic tap ch
1:59
ERS if you have frequent fluctuations
2:02
for large Motors consider soft starters
2:04
or vfds variable frequency drives to
2:07
control the starting current and reduce
2:09
stress on the motor make sure your
2:11
protection devices are in good working
2:13
condition because if they fail your
2:15
motor could burn out bottom line voltage
2:18
drop can be a silent killer for electric
2:20
motors especially under heavy loads keep
2:23
an eye on it take the right precautions
2:25
and your Motors will thank you with a
2:27
longer more efficient life that's all
2:29
for today if you found this helpful let
