AC- AC- technology technology offers offers the the following following advantages<br />
advantages<br />
in in comparison comparison to to DC- DC- technology:<br />
technology:<br />
♦ Maintenance-free operation<br />
� no mechanical wear and tear on the motor<br />
� no mechanical switch contacts (contactor)<br />
♦ Recuperation<br />
� without any additional components<br />
♦ More efficiency<br />
♦ More flexibility in construction Out<br />
� less wiring<br />
� the motor does not need to be openly<br />
accessible because it operates<br />
maintenance-free<br />
♦ Explosion protection<br />
� easy realizable due to no sparking in the<br />
motor<br />
