Copper & Aluminum Wire
In the main circuit of the motor there is a thermal relay (overload protection), when the motor overload, thermal relay action, normally closed contacts cut off the control circuit, normally open contacts closed to connect the indicator, overload excluded, the thermal relay contacts there are two reset to make the circuit restart work: manual reset – need to press the reset button;
Motor winding wire technology progress and trends, including three aspects, the first enameled wire development history, the second is the special application of enameled wire.
Enclosed low-voltage motor stator copper wire heat is first conducted to the teeth of the core, slot insulation thickness and thermal conductivity, slot insulation and copper wire and the core of the conductive thermal resistance between the winding temperature rise has a great impact.
As a result of the short-circuit turns generated within the loop current, so that the coil heats up quickly, further damage to the insulation of neighboring wires, so that the number of turns of the short-circuit is increasing, the failure to expand.
Thermal conductivity λ is a very large object is a good thermal conductor; and thermal conductivity is a small thermal conductor is a bad conductor or thermal insulator.
Copper conductor is an electrically conductive material made of copper with good electrical conductivity, thermal conductivity, malleability and corrosion resistance, and is one of the most commonly used conductor materials in the electrical and electronic fields
A high voltage motor is a type of motor whose output voltage is usually above the kilovolt level and is used to drive high voltage loads and high voltage equipment.
Insulation covering paint is a kind of insulating material coated on the surface of electrical components, which is used to protect the insulating performance and protection of electrical components.
Mica is a collective name for minerals of the mica family, which are aluminum silicates of potassium, aluminum, magnesium, iron, lithium and other metals, all of which are layered and have a monoclinic crystal system.
Copper-aluminum composite wire is a composite material composed of copper and aluminum layers, which is commonly used in the fields of electrical winding wires and high-voltage cables.
