Super high-efficiency type sensorless GNS1 Series

Super high-efficiency type sensorless GNS1 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
    Same mounting dimensions as an induction motor !
    Supports smooth replacement work via the same framedesign as an induction motor.
    Note: There are models with longer overall lengths than induction motors.

  • High power factor
    Possible to further reduce the power receiving equipment capacity !
    The higher power factor than induction motors and standard and high-efficiency 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.

Note 1

Contact us if a dedicated motor other than the base rotor speed of 1800 min-1 is required.

Note 2

Contact us when switching from commercial operation.

Note 3

Contact us if you require a special-purpose motor with a rated output of 7.5 kW or less.

Note 4

The above frame number is the same as the induction motor.

Grounding rings

earthling

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.
