Figure 3‐14. Regenerative operation of a lift equipped with a regenerative inverter (source: Mitsubishi)<br />
In Figure 3‐15, possible energy savings in lifts, using different technologies, can be seen. The<br />
use of a regenerative gearless VVVF drive can reduce the consumed energy to 19%, when<br />
compared to a conventional system, using a pole changing drive (two‐speed induction motor).<br />

3.4 Permanent Magnet Motors<br />
Permanent Magnet Synchronous Motors (PMSM) are rapidly becoming the leading motor<br />
technology within the lift market in Europe. It presents many advantages, such as a simplified<br />
mechanical system for the lift, improved comfort, reduced noise and vibration, and energy<br />
savings.<br />
