Construction of dc motor induction training programme-phase-i

  1. 1. Presented by;Mr. POKHARKAR S.V.,DATTAKALA POLYTECHNIC SWAMI-CHINCHOLILECTURER IN ELECTRICAL ENGINEERING DEPARTMENTCONSTRUCTION OF DC MOTOR1CONSTRUCTION OF DC MOTORBY MR.POKHARKAR S.V.DATTAKALA POLYTECHNIC SWAMI-CHINCHOLI
  2. 2. INTRODUCTIONIntroductory Stage- Learning Objectives- Daily use of motor indaily life. Eg.- Mixer,Fans, pump etc History-1)Basic Concept2)Fleming’s Left HandRule3)Working Principle After this session studentwill able to…………1)List the various parts ofDC motor.2)Draw Schematicdiagram of DC motor.3)Describe function ofvarious parts of DC motor.4)Explain the constructionof DC motor.2CONSTRUCTION OF DC MOTORBY MR.POKHARKAR S.V.DATTAKALA POLYTECHNIC SWAMI-CHINCHOLI
  3. 3. YOKE MATERIAL:- It is madeof galvanised iron(G.I.)with rolled heat treatment. FUNCTION:-1)It carries magnetic fluxfrom one pole to anotherpole.2)It acts as protectivecover to other parts.Viz-field pole, fieldwinding, armature coreetc.3)It provides space forfield pole housing byrivetting.3CONSTRUCTION OF DC MOTORBY MR.POKHARKAR S.V.DATTAKALA POLYTECHNICSWAMI-CHINCHOLI
  4. 4. EYE BOLT MATERIAL:- It ismade of hot rolled grainoriented(HRGO) mildsteel (M.S.). FUNCTION:-1)It helps for shifting ofmachine from one placeto other place OR forlevel change.4CONSTRUCTION OF DC MOTORBY MR.POKHARKAR S.V.DATTAKALA POLYTECHNICSWAMI-CHINCHOLI
  5. 5. FIELD POLE &POLE SHOE FIELDPOLE:- MATERIAL:- Itis made up of thin laminations ofSilicon Steel(S.S.)FUNCTION:-1)It provides space forhousing of field winding.2)It develop magnetic field whencurrent flows through fieldwindings. POLESHOE:- MATERIAL:- It ismade up of thin laminations ofSilicon Steel(S.S.)FUNCTION:-It provides maximum areafor injection of magnetic flux overarmature.5CONSTRUCTION OF DC MOTORBY MR.POKHARKAR S.V.DATTAKALA POLYTECHNICSWAMI-CHINCHOLI
  6. 6. FIELD WINDING MATERIAL:- It ismade up of copper(cu)wire with suitablegauge. FUNCTION:- Whencurrent flows through itexcited field pole fordeveloping magneticfield.6CONSTRUCTION OF DC MOTORBY MR.POKHARKAR S.V.DATTAKALA POLYTECHNIC SWAMI-CHINCHOLI
  7. 7. ARMATURE CORE & ARMATUREWINDING ARMATURE CORE:-MATERIAL:-It is made up ofvery thin laminations of siliconsteel.(S.S.)FUNCTION:-1)It provides slotsfor housing of armaturewinding.2)It cut’s the magneticfield developed by field circuit. ARMATURE WINDING:-MATERIAL:-It is made up ofcopper(cu) with suitable gauge.FUNCTION:-It develop EMF forproducing necessary torque dueto which armature startsrotating.7CONSTRUCTION OF DC MOTORBY MR.POKHARKAR S.V.DATTAKALA POLYTECHNIC SWAMI-CHINCHOLI
  8. 8. COMMUTATOR MATERIAL:- Itis made up of harddrawn copper(CU-99.7% & C-0.3%). FUNCTION:-For excitation ofarmature windingcurrent is giving from it.8CONSTRUCTION OF DC MOTORBY MR.POKHARKAR S.V.DATTAKALA POLYTECHNICSWAMI-CHINCHOLI
  9. 9. BRUSHES MATERIAL:- Itis made up carbon orgraphite. FUNCTION:- DC supply is giving tobrushes via commutatorit reaches towardsarmature winding.9CONSTRUCTION OF DC MOTORBY MR.POKHARKAR S.V.DATTAKALA POLYTECHNIC SWAMI-CHINCHOLI
