Permanent Magnets

The WMagnet uses powerful permanent magnets made from a combination of neodymium, iron and boron (NdFeB), and commonly referred to as rare-earths magnets. These magnets are some eighteen times stronger than traditional ferrite magnets.

CFW11 Frequency Inverter

Due to the dedicated software application which incorporates the vector control technology for driving permanent magnet motors, the use of the WEG CFW-11 frequency inverter together with the W22 Magnet motor is recommended.WEG CFW11 frequency inverters offer constant torque across a wide speed range, operating even at low speeds with efficiency levels above induction motors without requiring forced ventilation.

Reduced Mass and Volume

The magnets inserted into the rotor ensure a significant reduction in electric losses, and thus the motor temperature, enabling smaller frame sizes.
