• commutating windings, and • compensating windings. Armature windings are rotating-field windings, into which the rotating-field-induced voltage required in energy conversion is induced. According to IEC 60050-411, the armature winding is a winding in a synchronous, DC, or single-phase commutator machine, which, in service, receives The universal motor is modified in several ways to allow for proper AC supply operation. There is a compensating winding typically added, along with laminated pole pieces, as opposed to the solid pole pieces found in DC motors. A universal motor's armature typically has far more coils and plates than a DC motor, and hence fewer windings per coil. compensating windings provide proper compensa-tion for armature reaction. Stator end connection joints are TIG-welded together for maximum strength. Compensating winding straps are individually bolted at the centerline split to allow quick removal of the top half of the stator. All stator electrical conductors are made from copper.

The compensating winding may be simply shorted upon itself, so that it behaves like a short circuited secondary of a transformer (the armature winding acting as the primary). The induced AC current in the compensating winding again opposes the armature current and the motor is said to be inductively compensated. The reactance of the field In this video, you will learn about armature windings, lap and wave type of armature windings, equalizer rings and dummy coils. Department: Electrical Engine Basically armature winding of a DC machine is wound by one of the two methods, lap winding or wave winding. The difference between these two is merely due to the end connections and commutator connections of the conductor. To know how armature winding is done, it is essential to know the following terminologies - compensation, voltage control and energy conservation in a distribution system. In this chapter the conventional methods employed for reactive power compensation, their relative merits and demerits, desirable features of an advanced compensator in a distribution system are highlighted. 3.1 VAR Compensation: The current in the compensating winding will be in phase opposition to the current in the armature winding. Given below is the complete schematic diagram of the single phase AC series motor with all the modifications (i.e. compensating winding and inter pole). Reduction of Effects of Armature Reaction. Since the distortion of armature m.m.f. and compensating winding m.m.f. is not identical the complete neutralization of armature m.m.f. can not be achieved by using compensating winding. The armature m.m.f. under the pole shoe is neutralized whereas The compensation winding which is placed in the primary windon gives a volteg which is coupled in phase opposition to the voltage across Lp. The winding ratio is adapted so that influence of variations in mains voltage and load is reduced to a minimum. This winding gives a better voltage stability to the Reguvolt. FIG. 3 Arrangement of windings The compensation winding which is placed in the primary windon gives a volteg which is coupled in phase opposition to the voltage across Lp. The winding ratio is adapted so that influence of variations in mains voltage and load is
