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.
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.
How to withstand high temperature of permanent magnet motor?
Conventional design of drive controllers work in the ambient temperature is relatively stable conditions, and seldom consider the quality, volume and other indicators.
What are the phenomena of motor winding turn-to-turn short circuits?
When a short-circuit in the winding occurs, the method should be screened according to the actual situation and the corresponding measures should be taken to deal with it.
The role of motor winding dipping paint and common methods of dipping paint
After drying the winding dipping paint, do not use the wire brush to remove the paint film in the inner cavity of the iron core.
