These motors have good load behavior, but they do have prob\u00adlems, too: they can easily over\u00adheat and due to the wear of the carbon brushes need a lot of main\u00adte\u00adnance work. This is different for EC motors, as alter\u00adnating voltage is recti\u00adfied in the commu\u00adta\u00adtion elec\u00adtronics.<\/p>\n<p>But what does that mean? The stator, that is the stationary part of the motor, contains the wind\u00adings. The moving rotor contains perma\u00adnent magnets with alter\u00adnating poles. When the wind\u00adings are ener\u00adgized according to the desired speed and direc\u00adtion of rota\u00adtion, the rotor starts to rotate. The under\u00adlying commu\u00adta\u00adtion works as follows: Phase 1 is ener\u00adgized in such a way that the same polarity is produced as on the applied rotor magnet. Phase 2, on the other hand, is ener\u00adgized to the nega\u00adtive pole. The repul\u00adsion of iden\u00adtical and attrac\u00adtion of different poles starts the rota\u00adtion. The nega\u00adtive pole is now trans\u00adferred from phase 2 to phase 3. The motor then continues to operate in this way.<\/p>\n<p>As a result, an EC motor has a very high level of effi\u00adciency. This means that hardly any power is lost in the form of heat. In general, the motor hardly develops any heat, saves energy and is less expen\u00adsive due to the elim\u00adi\u00adna\u00adtion of main\u00adte\u00adnance work over its service life. It is also 25 percent lighter than AC motors with the same power. And it also runs very quietly. But best of all, it works as a plug &amp; play solu\u00adtion and does not require a trans\u00adformer control unit, a vari\u00adable frequency drive, or a motor protec\u00adtion switch, for example. Never\u00adthe\u00adless, it can operate in a broad and easily control\u00adlable speed range. Doesn\u2019t that sound convincing?<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Until now, hand-oper\u00adated elec\u00adtric tools were mainly oper\u00adated with so-called AC series motors.
