Electric Brake

1 Answer

Answer :

An electric brake is a device that uses electrically actuated components to stop or slow the motion of shafts. This type of brake is very useful in applications that require precise tension control and quick response times.

Electric brakes are classified into several types. Disc breaks uses a caliper that stops the spinning of a rotor or a wheel using brake pads. Cone brakes actuates when a cone lined with heat and uses a resistant material is pressed against a mating cup surface. Band brakes are the simplest. They feature a metal band covered in resistant friction material and lined with heat. Drum brakes work when shoes press against a drum, which is a spinning surface. They are normally used on rear wheels of automobiles.

If you are planning to order or purchase an electric brake, there are things you have to check to make sure you’re getting a good-quality and the appropriate product. These specifications include power, speed, operating voltage and rating. A spring-return brake requires power to engage. A spring-actuated brake needs power to disengage. Several engagement methods are available today. Wrap spring brakes use a wrapped spring to transmit torque from the input to the output to disengage the brake. Non-contact brakes use magnetic fields and eddy currents. Friction brakes produce friction between two contact surfaces.

In choosing the right electric brake, you have to analyze mounting configurations and measurements. You have to take note of the cross-sectional width of the device or the diameter; the dimension along the rotation axis or the length; and the weight of the assembly. Shaft configurations can be perpendicular to the axis of the load (in a way which forms a right angle), parallel but offset from the axis, or in-line along the axis. Shafts that attach to flanges and bores are often used in drive and load connections for electric brakes. With some bore-attached drive shafts, the output can be a sprocket, gear or pullet. Usually, these electric brakes are designed to accept various drive components.
