Special permanent magnet synchronous traction machine for passenger elevator safety and stable

The characteristics of permanent magnet synchronous traction machine:

• Switching brake noise is 5-10 dB lower than traditional permanent magnet traction machine;
• Traction efficiency is over 90%;
• Small size and light weight, are about 50-70% of traditional asynchronous traction machine;
• Low energy consumption, Which can save about 30-50% of electricity every year;
• Low temperature rise, maintenance-free and heavy load capacity;
• Suitable for products which loads up to 1600kg and speeds to 2.5m/s;
