The heart of a hair clipper is a mechanical motor that drives the blade. Let's look at three common types of engine engines, and the advantages and disadvantages of each:
The magnetic motor is found in almost all the cheaper models of hair clippers on the market. This engine design is simple and generally reliable, with few moving parts. The engine consists of a spring and an electromagnet that work in tandem to vibrate the blade back and forth. Although the magnetic motor provides less power than the other two engine models, it may be sufficient for occasional use.
The pivot motor is similar to a magnetic motor, but uses two solenoids and has no spring. Although the speed of the knife actually decreases, the pivot motor generates at least twice the power of cutting hair than magnetic motor hair clippers. This extra power makes combing wet hair a “knife through butter”. Machines with a pivot motor are used by professionals and are ideal for everyday cutting.
Rotary motors are the engine behind the most powerful haircut aprons on the market and come in AC (DC) and DC (one-way) models. Many DC powered models are cordless, battery powered. Although DC (DC) units are weaker than AC (AC) units, cable freedom can be a welcome pleasure. Appliances with rotary engines are often of the higher price range and are used for bulk hair removal as well as dog and horse care.
