Electric motors are relatively simple mechanical devices, but
rewinding new winding coil should only be undertaken by those who with
experience in mechanical or electrical repair. A mistake or poorly-performed
rewind job will result in a motor that doesn’t work and might be harmful to
your device. When your motor is defective we would recommend you to buy a new
motor or to take it to a professional shop for repair. Given the variety of
motors and types of windings can only be a general article on rewinding. If you
don’t understand the terminology, you shouldn’t rewind a motor; once you start
removing the original coils, there’s no going back. Thought the followings are
the most effective steps for those who are finding to rewind new coil
themselves.
Followings are the 13 steps
that are suitable for your rewind work.
1/ Clean your work surface to make sure
it’s free of dirt and dust.
For a comfortable and
non-disturbing to our executive, the work side should be clean and widely
enough avoid an unexpected risks. Therefore the necessary tools should be
prepared a complete set for easy going.
2/ consider
on the motor type. 3phases or single phase
There are several
differences winding coil connections and wire coil. between 3 phases motor
and single phase motor. To be able to rewind a motor effectively we must
understand clearly about this wiring coil connection.
3/ lubricate on the
fixing thing for easy taking the motor apart
Before we start to take the
motor apart to see the inside winding coil we should clean and lubricate
on the fixing things like bolts, nuts or screw and leave them a moment, so
we can release them more easier.
4/ carefully move out
end cap and the rotor
Before we start to remove
the end cap and the rotor to see the inside Winding
coil we would rather to document or make a note on the motor Body, so that
it is easy for us when we rebuild it.
5/ illustrate the modern of winding coil and its connection type
It's the
most important to understand about the winding coil modern and its interaction winding connection, otherwise
you can not reestablish and active motor.
It's the main key for technicians who are trying to rewind a motor and should be trained thoroughly.
6/ carefully move out the existing winding coil
After
you finished making a note on the winding coil modern and its connection
we can start to move out the existing winding coil. However you do to move
it out. It depends on you but not to damage the stater core otherwise
it may result any change.
7/ count the number of wire turns in each winding coil
carefully,
when you move out the winding coil from each stator slot you have to put
back at the same number of wire turns and at the same modern. if
everything is changed your device will work abnormally or absolutely not
work. So the rewinding work should be executed by a qualified technician.
8/ clean the hard stator core
when
you completely moved out the winding coil the next work is to clean your
hard stator core to make sure it's not damaged or wet. Remove all the dust
or dirty on its surface.
9/ insulation the
stator slots
the
insulation is offered to prevent stator core from electric
potential passing through the wire. The plastic seed is a good and
suitable insulation sticking closely to the stator slots.
10/ rewind the new
winding coil
the new winding coil must
be made at the same pattern as the old winding removed. The number of wire
turns and its wide dimension must be specific related to the illustration
you have made.
11/ insert the
rewinding coil in to the stator slot
the inserting work must be
don't carefully and correctly. Not to scratch or damage the wire
insulation. Besides, you must be careful with the interaction of winding
connection. There are two connection types of stator winding.
12/ insulation the winding coil
when the rewinding work is
finished, the next step is to insulate the wire coil by varnish. Cover the
winding thoroughly by
the varnish and warm it up.
13/ rebuild your motor
at the end step is to
rebuild your motor. Rebuild carefully and related to the illustration or
document you marked. Then connect it to an available power source to test
the operation. Measure the cost of ampere whether it's according to its
nominal ampere and keep it working for a period of time to see if it is
hot or not.
