Permanent magnet AC (PMAC) has many advantages over AC induction motors, including higher efficiency and power density. LEESON® SyMAX PMAC motors have an added benefit: All stock SyMAX motors come with an AEGIS® Shaft Grounding Ring factory-installed.
LEESON SyMAX's benefits include:
High efficiency, up to IE4: Energy costs are 95% or more of electric motors' total cost of ownership. SyMAX motors have efficiency 1-3 points above IE3. Higher efficiency means lower electric bills.
Higher reliability, less maintenance: PM motors run at lower temperatures than AC induction motors, so they have longer bearing and insulation lives and require less maintenance.
Drop-in replacement: In most installations, SyMAX motors can be swapped in for existing NEMA and IEC frame motors without further system modifications.
Higher power density: Higher power density than AC induction motors means that you can get more power out of the same frame size, or the same power out of a smaller frame size.
Protection from voltage stress: SyMAX motors have the patented MaxGuard insulation system and an AEGIS ring mounted inside, to protect the motor from damage caused by the drive's output.
Long Warranty: SyMAX motors come with a three year warranty from LEESON. On top of that, the AEGIS ring inside comes with a 2-year extended warranty against bearing fluting damage.
