Dol PM synchronous motorsDertec DOL PM synchronous motors are the future when speaking about energy efficiency. Today the world is searching for energy use and CO2 reduction. Dertec DOL PM Synchronous motors offer high efficiency of average of 92%. DOL means Direct Online ( also called line start ). The Dertec motors can be used without | ![]() |
Specs & versions
Dertec DOL Synchronous PM motors are available in frame size IEC71 upto IEC90. Available motorpowers are 0,37, 0,55, 0,75, 1,1 and 1,5 kW at 1500 Rpm. DOL motors can be connected to the power source and will startup without an inverter. The use of Permanent magnets and a smart design of a squirrel cage rotor makes it possible to start up these motors without the use of an inverter. Due to the construction of these motors they offer a high efficiency ( upto IE5).
Important advantages of these motors are:
- High efficiency, also at partial load.
- High Cos Phi, also at partial load.
- Synchronous speed of 1500 Rpm.
