What Are Wound Field Motors And Where Are They Applied

Dc Motor Field Winding Designs

The winding that produces the working flux and do not vary with load is the exciting or field winding.

Dc motor field winding. Most three phase ac field coils are used to generate a rotating field as part of an electric motor. A dc motors speed can be controlled over a wide range using either a variable supply voltage or by changing the strength of current in its field windings. Larger ac motors are. Statorstationary part rotor rotating part.

All rotating machines have 2 parts. The field winding basically form an electromagnet that produces field flux within which the rotor armature of the dc motor rotates and results in the effective flux cutting. All rotating machines have 2 parts. Small dc motors are used in tools toys and appliances.

The field winding of dc motor are made with field coils copper wire wound over the slots of the pole shoes in such a manner that when field current flows through it then adjacent poles have opposite polarity are produced. Direct current dc motor field windings 25092011 by lemau 2 comments dc motor is the one of common application for industrialit have several advantage compare with ac motordc motors applied for the momentarily deliver rated around three or more times from their torque. Single phase ac motors may follow either of these patterns. The winding that produces the working flux and do not vary with load is the exciting or field winding.

The universal motor can operate on direct current but is a lightweight brushed motor used for portable power tools and appliances. There are 2 types of winding too. Most dc field coils generate a constant static field. The motor design is referenced by the method these two components are wired together.

Field armature winding. The field windings and armature of the dc motor can be wired in various ways. If motor has field windings look voltage and current values for field in name plate calculate resistance and check by measuring usually brushed dc motor has two four or six brush holders take away brushes so that only one pair is left in place in opposite sides difference 180 degrees. In addition many motors are using permanent magnet fields.

There are 2 types of winding too. As you already know there are two electrical elements of a dc motor the field windings and the armaturethe armature windings are made up of current carrying conductors that terminate at a commutator. Field armature winding.
