Electromagnetic wire is an insulated wire that generates a magnetic field or induces a current in the magnetic field after being electrified. It is mainly used for windings of related electromagnetic equipment such as motors and transformers. Its conductor is mainly copper wire, with thin insulation layer and good electrical and mechanical properties, as well as heat resistance, moisture resistance and solvent resistance. Different characteristics can be obtained by selecting different insulating materials.
Such as: common plastic insulated single-stranded copper core wire, cross-sectional area 1.5, per1200m weight1.8-1.9kg; 2.5 plastic insulated single copper core wire, with a weight of 2.8-3.0kg； per 100m; 4.0 Plastic insulated single copper core wire, with a weight of 4. 100m/-4.2kg..
Extended data:
1. According to the structure and working principle, motors can be divided into DC motors, asynchronous motors and synchronous motors. Synchronous motors can also be divided into permanent magnet synchronous motors, reluctance synchronous motors and hysteresis synchronous motors. Asynchronous motors can be divided into induction motors and AC commutator motors. Induction motors are divided into three-phase asynchronous motors and so on.
Phase asynchronous motor and shielded pole asynchronous motor, etc. AC commutator motor is divided into single-phase series motor, AC -DC dual-purpose motor and repulsion motor.
2. Classification of motors according to starting and running modes Motors can be divided into capacitor starting single-phase asynchronous motors, capacitor running single-phase asynchronous motors, capacitor starting single-phase asynchronous motors and split-phase single-phase asynchronous motors according to starting and running modes.
3. Motors can be classified into drive motors and control motors according to their uses.
The driving motor is divided into electric tools (including drilling, grinding, polishing, slotting, cutting, reaming, etc.). ) and household appliances (including washing machines, electric fans, refrigerators, air conditioners, tape recorders, video recorders, DVD players, vacuum cleaners, cameras, hair dryers, electric razors, etc. )
Motor and other general small mechanical equipment (including all kinds of small machine tools, small machinery, medical instruments, electronic instruments, etc.). ). Control motors are divided into stepper motors and servo motors.
