Eaton Cutler-Hammer 511 7" AC Brake, Type S-7 Size, 480v/60hz coil
50 Lbs Continuous Torque 50 Lbs Intermittent Torque
The industry standard magnetic shoe brake - proven quality & reliability.
Complete units, wheels, & renewal parts available from Tri-State Electrical Supply. Product Description
Eaton Cutler-Hammer Type S brakes from Eaton's Electrical Business are electrically released & spring applied providing "fail-safe" operation.
The retarding torque developed is directly proportional to the spring pressure.Application Description
* Machine tools
* Printing presses
* Overhead doors
* Dumb waiters
* Vacuum molding machines
* Carnival rides Features
The brake wheel is of relatively large size in relation to the torque developed by the brake.
This permits use of a larger brake shoe lining and lower shoe pressures.
Low shoe pressure, equally distributed over a large lining area, results in even wear of the friction surfaces and even braking torque.
The oversize wheel type construction also permits use of a smaller operating solenoid that requires less current for a given torque rating.Brake Selection
The method most generally used to determine required braking torque is to calculate the full load motor torque by the following formula:
T = 5252 x hp
T = Full load motor torque in lb-ft
HP = Motor horsepower
RPM = Speed of shaft on which brake wheel is mountedMounting
Type S brakes are designed and recommended for use and mounting only in the horizontal position.
Side or vertical mountings are not recommended because the solenoid loading is altered, resulted in accelerated wear and premature coil failure.
