DMB系列（DMB-20，DMB-30，DMB-40，DMB-50，DMB-60，DMB-90，DMB-W100，DMB-W120，DMB-W150）
ACTION:

DMB brake is an electromagnetic actuated type which produces the braking force when the coil is excited. Exciting the coil, field magnetizes rotor and armature is attracted to the facing, and then braking force is produced with its friction. Interrupting the coil current, magnet releases armature with release spring to the former disconnected position. Clutch torque is adjustable to change the coil current.
