The use of the insulating material of the motor

Insulating materials in the motor:
Insulating material: the ability to block the current through the material, the volume resistivity is usually greater than 109Ω.cm
3 motor: electromagnetic energy conversion machinery and equipment
Motor classification: transformers, DC motors, AC motors, control motor, pulse stream motor
5 basic structure of the motor: a stationary part (stator): generating a magnetic field, to constitute a magnetic circuit, the mechanical support. The gap (air gap): to ensure that the important part of the safe operation of the magnetic circuit of the motor, the rotating part (rotor): induction electric potential, and the electromagnetic torque, energy conversion.
Stator structure: Machine seat, the main magnetic pole, the commutation electrode, the end cap, the brush means.
The structure of the rotor: the rotary shaft, an armature core, armature windings, commutator.
6. Armature windings: by a certain number of armature coils according to certain rules connected component; is a circuit portion of the DC motor, but also the induced electromotive force, generates electromagnetic torque electromechanical energy conversion portion
7. Manufacturing motor uses the main material: the conductive material (the windings, the commutator, the brush), the insulating material (to the live parts of the grounding member, and different potentials of the live parts, with the core, stand, etc. are electrically separated), the permeability The material (for the various components of the system of manufacturing magnetic core, stand, etc.).
The 8. Motor insulation structure: inter-turn insulation layer insulation, insulation on outsourcing insulation. There are three, filled with insulating liner insulation insulation commutator.
Inter-turn insulation: main pole coil and commutation coil turn insulation, insulation between the armature coil turns, the commutator segments, chip insulation, the insulation between the turns of the same coil
Interlayer insulating; layered flat around the insulation between the layers of the main pole coil, the armature winding of the front and rear end section portion, the groove portion, a lower insulation between the coil between the upper and lower layer of the insulating
Insulation to ground: refers to the insulation between the respective windings of the motor on the chassis and other uncharged member, the main pole coil change to the pole coil insulation, an armature winding insulation to ground insulation of the commutator, the motor live parts and the base, core the uncharged components isolated to prevent breakdown occurs on the ground.
Outsourcing Insulation: insulation package to insulation outside, mainly to protect insulation from mechanical damage and the entire coil seed formation, also played a reinforcing effect of the insulation
Fill insulation: filled coil gap, so that the entire coil firmly to form a whole, to reduce vibration, the coil forming the rules, formation, facilitate the bandage on the insulation, but also conducive to heat
Liner insulation: protection from mechanical damage insulated structure in the process operation
The commutator insulation: isolating converter commutation patches between insulation to slice group, reversing ring to the V-shaped piece group and pressure ring mica and mica sleeve, the multilayer quality shellac plastic mica
The 9. Stator bars wire insulation: Row Insulation transposition insulation transposition fill.
10 generator rotor insulation: the insulation between turns, pole pallets, polar body insulation.
