Description   Electric brakes are actuator devices that use an electrical current or magnetic actuating force to slow or stop the motion of a rotating component. They are used in industrial and vehicular braking applications that require fast response times and precise tension control.   How Do Electric Brakes Work?   There are two main types of electric brakes: magnetic and friction. Each has various subtypes. As described below, the way an electric brake works depends upon...

Applications and UseTop

Q:
What are some of the applications you have used electric brakes for?
15 answers
Answers:
I have used reverse power brakes in stopping filament rayon spinning motors which run at 25000 RPM. These are motors run at 125 frequency twin poles. Initially we used Toshiba motors and later we manufactured our own motors from scratch. Groups of 6 motors are controlled by one switch. Each spinning hall had more than 2000 motors which had a spinning pot on the each spindle.
~Radhakrishnan C., Self Employed, Bangkok, Thailand
We have installed a Hydrastar onto a Horsebox (we had to source it from New Zealand as USA did not respond to our emails). Electric brakes would have been much more professional.

Answers:
Electric train locomotives can be 100% driven by electricity and using reverse power brakes. Many laboratory equipment can use electric brakes.
~Radhakrishnan C., Self Employed, Bangkok, Thailand
Position holding of an axle instead of slowing down rotation.
~Sebastian H, Design Engineer, Utrecht, The Netherlands

Q:
Do you know of any disastrous mistakes that occurred due to the incorrect usage of electric brakes?
3 answers
Answers:
I have no idea , except for the failures which made one of the car manufacturers withdraw vehicles from the market.
~Radhakrishnan C., Self Employed, Bangkok, Thailand
Used as a dynamic brake although it was designed as a static brake.
~Maikel O, Engineering Consultant, Xiamen, China
Low torque, brakes undersized, slipped and burned up quickly.

FeaturesTop

Q:
What would your design or feature "wish list" be for this product?

Q:
Is there any advice you want to share with users to help them avoid common errors in selection or usage of electric brakes?
4 answers
Answers:
If you want to provide greater reliability and repeatability as well as heat dissipation, look for electric brakes that use oil shear technology. The brakes run cool with no downtime, long life and no maintenance or adjustments.
~Rick F, Marketing/Sales, Fairfield, OH
Although I am not a specialist, I can comment selection of electric brakes must be made with the help of a number of vendors and compare the vendor's qualifications, specific recommendation versus user's requirements and price.
~Radhakrishnan C., Self Employed, Bangkok, Thailand
USA electric brake controllers do not comply with United-Nations/ECE Regulations.
~Noel H, Engineering Consultant, Johannesburg, South Africa
Carefully follow the supplier's advice/spec which comes with the brake.
~Sebastian H, Design Engineer, Utrecht, The Netherlands

Buying AdviceTop

Q:
Do you have any advice for people relative to buying or using electric brakes?
4 answers
Answers:
Heat buildup is the mortal enemy of electric motors. It can destroy conventional dry friction electric motor brakes. Dry brakes have a short life.
~Rick F, Marketing/Sales, Fairfield, OH
Depends on use. Each use will have user specific conditions and hence have to be examined individually.
~Radhakrishnan C., Self Employed, Bangkok, Thailand
Find a stable supplier
~Sebastian H, Design Engineer, Utrecht, The Netherlands
Go for them.
~Noel H, Engineering Consultant, Johannesburg, South Africa
