Filter Reactors

Filter reactors function to prevent rapid current change of high-voltage circuits.
Although filter reactors are insulated, the insulation material deteriorates from long-term use, possibly resulting in unexpected grounding phenomenon.
Fuji Electric Machine Manufacturing provides repair services such as coil re-winding and insulation renewal by re-impregnation.
We can also provide service for both continuous winding (spindle type) and disk types of filter reactors.

Tacho-Generators

Tacho-generators are an important devices that provide highly precise measurement of the speed of railroad vehicles.
Although the consumable components of tacho-generators become worn due to long-term use, resulting in inaccurate output values, our repair services provide recovery of accurate output characteristics.
In addition to repair, we also provide periodic inspection.
