D/C Motor Winding & Repair

Everything that has been said about the craftsmanship involved in rewinding A/C electric motors applies to D/C electric motor  rewinds as well.   The difference is that D/C motor rewinds require even more skill and training on the part of the winder.

From random-wound to form-wound, rewinding D/C motor armatures and field coils is craftsmanship at its highest level.   Highly skilled craftsmen are absolutely vital to every step of the rewind process.   At EMS, we have worked hard over many years to refine the art of rewinding D/C electric motors.   The result of our extensive research and development is the unparalleled quality which separates an EMS rewind from all others.

At EMS, we know that it is one thing to "talk" about quality, and it is quite another to back it up.   And so, while our competition has been busy talking about quality, EMS has been busy delivering quality.   It's a big difference in philosophy, and one that our customers appreciate.

All of EMS's superior rewinds are composed of three things.  Materials, Technique, and Commitment.

Materials make up the first ingredient.  The materials we use are the best that are commercially available.   EMS begins by utilizing a Class 180 temperature rated insulation system for all our rewinds.   Most of our competitors use Class 155 insulation or lower.   Sometimes, much lower.   The higher Class 180 rating means that our rewinds will withstand higher temperatures... up to 180^oC.  

We begin by using magnet wire which has additional insulation.   It will withstand more punishment than regular magnet wire, and is designed to take the severe punishment that D/C motors experience.

We continue by installing insulation materials which are all rated Class 180.   These are materials you may never see, but they are indispensable parts of our insulation system.   For example, our slot insulation, coil separators, and top wedges are all constructed of Class 180 materials.   All rewinds are preheated, dipped, and baked in a Class 180 electrical insulation varnish a minimum of two times or more, depending upon application.

At EMS, use of inferior materials to save money is NOT an option.  We have learned that utilizing superior materials is the best way to save our customers money, long term.   It's easy to see... Superior Materials = Superior Rewinds.

Technique is the second ingredient of a superior EMS rewind.   Our rewinds require more than simply the best materials.   An EMS rewind is the best because of the proven techniques we use in conjunction with our materials.   Our formula is simple... superior techniques combined with superior materials produce superior rewinds.   Our techniques are the result of decades of studying rewind procedures.  Every step in the total rewind process has been carefully examined, refined, and verified to produce the highest quality D/C armature and field coil rewinds.  

We also carefully inspect the commutator mechanically and electrically, performing bar-to-bar and other testing.   We utilize a lathe to turn and undercut the commutator to provide a smooth surface for the brushes.   As if that were not enough, each rewind is then put through a rigorous testing procedure that insures it will last in the field.

Commitment is the third ingredient of an EMS D/C armature or field coil rewind.   An EMS D/C Electric Motor Winder is by definition a skilled craftsman who possesses years of experience.   We are self-motivated individuals dedicated to quality.   It is the commitment of the winder that takes the materials, utilizes the techniques, adds their years of experience, and creates the superior EMS winding.  

All of the above allows our D/C armature and field coil rewinds to keep running long after normal rewinds have failed, which translates into more uptime and less downtime.   And that is what it's really all about.

We have placed photos of actual EMS rewinds on this page, in order for you to see the quality for yourself.
