. They replaced many of the aging 6000 series and new 6000 series
sets.
.
This series adopted variable-frequency drive motors named "Hitachi HSV-03"; the motor power is 150 kW and installed as 4 motors per car. Power cars are two cars as one pair. The 8100 car establishes the VFD-controller, and the 8200 car establishes a compressor
, etc.
The brake system was finished with Hitachi HSC and adopted brake by wire with regenerative brake
.
Bogies are based on the New 7000 series, too. The name is "KH132B" (for power cars) and "KH135B" (for others). They have stand out disc brake
