There are many technical terms in the world of electric motors. We have collected a brief dictionary of basic concepts so that you can easily understand the masters and documentation.
Main components
- Stator - the stationary part of the motor with a winding.
- Rotor - the rotating part.
- Winding - coils of insulated wire that create a magnetic field.
- Squirrel cage - a type of rotor made of rods closed by rings.
- Commutator - a DC motor unit for supplying current to the armature.
Characteristics
- Efficiency - the share of useful energy.
- cos φ - coefficient power.
- Slip - lag of the rotor from the magnetic field.
- Insulation class (B, F, H) - permissible winding temperature.
- IP - degree of protection from dust and moisture.
- IE1–IE4 - energy efficiency classes.
Types work
| Term | Value |
|---|---|
| Rewinding | Replacing damaged winding |
| Impregnation | Winding treatment varnish |
| Balancing | Eliminating rotor imbalance |
| Alignment | Aligning the axes of the engine and mechanism |
| Tracking | Treating inter-lamella spaces collector |
Faults
- Interturn short circuit - short circuit of adjacent winding turns.
- Insulation breakdown - short circuit of the winding to the housing.
- Phase failure - disappearance of one of the three phases.
