What kind of motor is best? This is the most common problem. The production of motors includes these physical parts: magnets, iron core, coils, base, Hall, insulating paint, and phase wires.
Magnetic steel has five indicators: label, height, thickness, width and quantity. The label represents the reflection of the magnetic flux per unit volume, which is the grade of the magnet. Height, thickness, width and quantity, of course, are higher, thicker, wider and more. The larger the magnet volume, the higher the cost for the motor manufacturer, and the greater the power for the user, which of course also means more consumption. The power will be greater.
In line with the principle that the higher the manufacturer's cost, the greater the user's interests. On the premise of meeting the strength requirements of their own use, the bigger the better in terms of height * thickness * width * quantity. However, generally speaking, for users, thickness, width and The quantity cannot be determined.
Coil, copper purity (brass or copper, as long as it is not copper-clad aluminum), number of turns, thickness, slot full rate, these are the main parameters.
Once the base is determined, the upper limit of the space indicators involving quantity and volume will be determined.
Insulating paint requires higher temperature resistance, the better.
The thicker the phase wire, the better. Generally, 1 square meter (excluding rubber) can meet the 10A current limit. For example, if your current limit is 20A, the phase wire should be more than 2 square meters.
Power - one of the motor indicators. Divide the speed of the motor by the voltage. This result is more accurate.
Efficiency (power saving)----The motor we are using generally has an efficiency of about 82%.
