What is the difference between induction and universal motor?
In terms of construction and indication of use, the main difference between current machines is in the type of engine they use, universal or induction.
Universal motor Universal electric motors use brushes to generate the electromagnetic field that makes the rotor rotate. With a simpler structure, they are indicated for moderate use , with only a few hours of use per week.
Main advantages of models with universal motor: * Low cost: Allow products with affordable prices;
* Weight: make the devices very light and portable;
* Simplified maintenance: Simple wiring and connections facilitate repairs.
Disadvantages of models with universal motor:
* Less durability: In addition to being high-speed motors (average of 19,000 turns), they have greater wear due to the constant impact of the brushes with other internal structures, which requires the replacement of these parts regularly;
* Less resistance: They are engines that allow less time of weekly use (from 2 to 5 hours), which limits them to residential use;
* Higher noise level: Because they work with high speed and because they induce and break inductive circuits constantly, these motors are much louder.
Induction Motor Induction electric motors do not use any type of brush to induce electromagnetic fields. This is because this field is induced in the part of the motor that is static (stator).
