For DC magnetic brakes, however, the operating coils are shunt wound for across-the-line connections and series wound for connecting in series with DC motor
When the brake coil is energized, the armatures move together to compress a torque spring and move the shoes away from the wheel, thus releasing the brake. De-
Braking torque is set correctly at installation and requires no major adjustment except when shoe/linings are renewed. Electro Magnet. Brake magnets are series-
