For over a century the carlyle johnson machine company has manufactured quality electromagnetic brakes electric motor brakes and power transmission products.
Electric motor brake.
These brakes are typically used on or near an electric motor.
Beyond our core brake technology keb is able to offer custom designs which help motor manufacturers during assembly and.
In an ac induction motor when the ac voltage is removed the motor will coast to a standstill over a period of time since there is no induced field to keep it rotating.
The friction disc with the hub is coupled to the motor shaft to be braked but is capable of moving axially.
In the event of power failure the brake would engage.

Gear motor brakes are power off style brakes designed to stop or hold a load that is coupled to the armature hub assembly.
An electric brake is commonly used in corded tools such as circular saws miter saws routers.
They are most commonly used in commercial duty for small gear motors.
Use them with a current limiting transformer to adjust the electrical current which controls the amount of torque applied.
Since the coasting time may be unacceptable particularly in an emergency situation electric braking can be used to provide a more immediate stop.
Electromagnetic brakes electric motor brakes.
When power is off a spring force clamps the friction disc between a pressure plate and a.
One version has contains a brake internally connected to motor leads.
Typical applications include robotics holding brakes for z axis ball screws and servo motor brakes.
Finally a word about brake motors.
An electric motor brake commonly referred to as an electric brake is a safety feature incorporated into many modern power tools such as circular saws drills and miter saws many manufacturers implement this feature into tools specifically with a spinning blade or cutter.
We offer a variety of standard industrial electromagnetic brakes all of which can be modified to meet your needs and requirements.
Keb has been supplying motor brakes since our founding this gives us more than 48 years of experience.
Multiple disks can also be used to increase brake torque without increasing.

Many motor manufacturers offer two types of brake motors.
As such on cannot use separate power sources for brakes and motors.
Only across the line or full voltage motor control should be used with these motors.
Electric motor brakes are used to decelerate or hold motor loads when the power is cut intentionally or accidentally.
