High-efficiency type sensorless GNP1 Series

High efficiency and energy savings
Motor efficiency same level as IE4 (super premium efficiency) !
Note: IE4 is an efficiency class based on IEC 60034-31.
Easy replacement and light weight
Same mounting dimensions as an induction motor, and lightweight !
Same mounting dimensions as an induction motor, while achieving a lightweight structure. Smooth replacement is possible.
Note: The overall length of the 75 and 90 kW types is longer.
High power factor
Possible to further reduce the power receiving equipment capacity !
In addition to high efficiency, the higher power factor than induction motors and standard type synchronous motors can greatly reduce the current capacity of the equipment.
Maintenance friendly
Easy bearing replacement !
The bearings can be replaced without taking out the rotor in the same manner as the standard type synchronous motor. In addition, replacement can also be done on site, making it possible to improve work efficiency.

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.
