Electromagnetic brakes work like this. The brake shoes are moved by solenoids. These solenoids actually keep the brakes OFF when power is going to them. When the electronic brake is actuated, the brake control decreases the amount of voltage going to the solenoids there fore allowing the brake to contact the brake drum. When the safety switch (break away switch) is activated, the battery in the supply box, provides full power forcing the brake pads against the drums causing the vehicle to stop immediately.
Probably the reason is in the different voltages between the star and delta connection voltages. An electromagnetic brake designed for the lower voltage of the star connection would burn out or open when introduced to the higher voltage of the delta connection.

The electromagnetic brake is used in many different fields. For example, metallurgy, construction, chemistry, food-prompt and accurate braking effect, automatic doors, stage apparatus, medical appliances.
A electromagnetic bell works by a electrical circuit.
The best elliptical machine is Electromagnetic Brake Resistance.
No brake pads to wear out. Can't overheat the brakes.
Electromagnetic waves are waves which can travel through the vacuum of outer space.

my back brake lights don't work, but the brake light on the back door does what could be wrong
