Synchronous Motors
Standard type with sensor GNF2 Series

-
High efficiency and energy savings
Motor efficiency same level as IE3 (premium efficiency)!
Note: IE3 is an efficiency class based on IEC 60034-30. -
Supports advanced speed control
Capable of PG vector control !
It is suitable for applications such as printing machines and press machines. -
Compact and lightweight
Volume ratio: On average 35% improvement,
Mass ratio: On average 40% improvement ! (in-company comparison)
The motor frame number of frames 1 to 3 is lower than that of induction motors. Machinery can be made compact and space-saving. -
High power factor
Reduces the power receiving equipment capacity !
In addition to high efficiency, the higher power factor than the induction motor can lower current capacity of the equipment.

Grounding rings

In general, a grounding brush is incorporated in motors with frame numbers of 225 or higher to prevent bearing electric corrosion. The grounding brush is a consumable part and must be replaced periodically. A maintenance-free grounding ring (Aegis® SGR) is also available as an option when it is difficult to replace the grounding brush depending on the installation location or operating conditions.
