6" Permanent Magnet encapsulated motor (PM) up to 45 kW Franklin Electric

The 6" Synchronous encapsulated motor is characterized by up to 15 points (21%) improved efficiency. The submersible motor’s permanent magnet equipped rotor eliminates rotor losses thus significantly reducing motor current and heat rise. In many cases, reduced motor current equals less drop cable cross sectional area further reducing overall installation cost. Excellent partial-load efficiency of permanent magnet motors allows the entire power range to be covered with only a few different motor sizes, thus offering important stock-keeping advantages.
