What is the meaning of 'uni directional control' for electromechanical brakes?

In summary, the conversation is about integrating an electromechanical brake into a system with a bi-directional rotating shaft. The brake in question is the SB-70B24-E32S from Thomson Linear Company's catalogue. There was confusion regarding the brake's unidirectional control feature, which was clarified to mean that the brake can only be controlled to brake in the direction it is moving. It was also mentioned that Thomson does not offer any controls for this brake and many people choose to simply wire it up and remove power when braking is necessary.

hello i have a system consisting of bi directional rotating shaft.i would like to integrate a brake in the system for stopping the shaft.
i m interested in an electromechanical brake in thomas linear compnay's catalogue(http://www.thomsonlinear.com/en/product/SB-70B24-E32S).
They have mentioned that the brake has uni directional control.
what does that refer to. please help.

uni means one, so the unit can only brake in one direction. ie it can apply an anti clockwise braking torque but not a clockwise braking torque (or vice versa).

Actually i have asked the company's application engineer. He said otherwise. The full text below for all to benefit:
1st email:Part number SB-70B24-E32S is a brake only. Thomson does not offer any controls for this brake either and we are unsure what specifications you are speaking of below that speak of unidirectional control since the SB series brake will run both clockwise and counterclockwise or in other words, bi-directional.There are not any specifications in Thomson literature that speak of a control for these units. Could you please clarify exactly what assistance you require?Thanks,
2nd Email:uni directional control is just a feature of the product meaning that you can control it to brake in the direction it is moving. It is just a way to word that if you are moving one direction that is the direction it will brake if you are using it dynamically. If you are using the brake as a holding brake then this would not apply. This is not saying that Thomson offers a control for the unit or that one is required. Many people just choose to wire the unit up and remove power when the braking is necessary.
 

1. What are electromechanical brakes?

Electromechanical brakes are braking systems that use both electrical and mechanical components to stop or slow down a moving object. They typically consist of an electric motor, a mechanical actuator, and a friction material to create friction and stop the motion of the object.

2. How do electromechanical brakes work?

Electromechanical brakes work by using an electric current to activate the electric motor, which then turns the mechanical actuator. The actuator then applies force to the friction material, creating friction and stopping the motion of the object. The amount of force applied can be controlled by adjusting the electric current.

3. What are the advantages of using electromechanical brakes?

One advantage of electromechanical brakes is that they provide more precise control over the braking force compared to traditional mechanical brakes. They also have faster response times and require less maintenance since there are fewer moving parts.

4. What are the applications of electromechanical brakes?

Electromechanical brakes are commonly used in various industries, including automotive, aerospace, and manufacturing. They are also used in elevators, escalators, and other transportation systems. They are also increasingly being used in electric and hybrid vehicles.

5. What are the potential drawbacks of using electromechanical brakes?

One potential drawback of electromechanical brakes is that they can be more expensive to manufacture and install compared to traditional mechanical brakes. They also require a power source, which can be a disadvantage in certain applications. Additionally, if the electric system fails, the brakes may not work, unlike mechanical brakes which can still function even if the power source is lost.
