Advantages of self-adhesive enameled wire in terms of reliability
Self-adhesive enameled wire (self-fusion enameled wire) is a conventional enameled wire surface, coated with a layer of self-adhesive lacquer, cured self-adhesive lacquer can be ethanol melting, high-temperature melting to achieve the second melting, so as to realize the bonding between adjacent enameled wires.
Basic Concept of Brushless Motor
According to the structure and working principle of the motor, we can categorize the motor into brushed motor, inner rotor brushless motor and outer rotor brushless motor.
Where exactly are brushless motors hidden in everyday life?
The practical application of brushless motors in life is everywhere. In the near future brushless motors will make more contributions to the convenience of life for the masses.
What are the adverse effects when the iron core is magnetically saturated?
Iron core is an important component of the magnetic circuit of the motor product, the main material of the core is silicon steel sheet, different performance of the motor, may require different grades and thickness of silicon steel sheet to meet the final magnetic performance requirements.
Types of motor windings and technical requirements for welding
The life and operational reliability of the motor depends mainly on the manufacturing quality of the windings and the effects of electromagnetic action, mechanical vibration and environmental factors during operation.
Why are motor rotors slotted?
“In order to control the asynchronous motor noise, in addition to selecting the appropriate stator-rotor slot fit in the design, a sloping slot can be used to reduce the electromagnetic noise of the motor.
Is it possible to determine the efficiency of a motor directly from the amount of motor current?
For motor products, its efficiency value will be analyzed and calculated in accordance with the standard type test data, in the motor factory test, each motor manufacturer has its own judgment standards, according to the motor type test results to determine the motor’s no-load current and no-load loss floating range, and qualitatively determine whether the motor’s efficiency index is in line with the requirements.
What is the reason that the insulating varnish flakes off after the motor winding is dipped in paint?
Dip paint, is an important part of the winding insulation process, dip paint winding, after the necessary drying process, through the insulating varnish so that the wire and other materials, bonding, curing as a whole.
Brief analysis of coil insulation structure
For motor products, the winding is the heart of the motor, the winding itself should be insulated with the core and other parts, if it is a three-phase motor, the winding should be insulated between phases as well.
