MKS7 series (Inverter-driven NB)

Inverter brake motor.
Unique soundproofed structure of the brake section drastically reduces jarring metallic sounds during braking. (Reduction of 10 to 15 dB(A) compared with conventional products.)
Non-asbestos brake linings used from 1990 ensure non-polluting products.

MKE6 series (Standard EB)

Unique soundproofed structure of brake section drastically reduces brake operation sounds. (Reduction of approximately 10 dB(A) compared with conventional products.) Unique brake control system uses only 3 wires.
Non-asbestos brake linings used from 1990 ensure non-polluting products.

MKC7 series (Standard NB)

Very simple construction with a compact DC-excited electromagnetic brake built into the non-driving side of the standard motor.
Strong magnetic force by DC is used for the all-important braking function.
