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.
How to solve the vibration problem of the motor?
Motor and all other machinery and equipment, in the operation process there is energy, heat, wear and tear, vibration and other physical and chemical parameters of the transfer and change, these changes in information...
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.
