HIGH-SLIP BRAKING SOFTWARE PUTS THE BRAKES ON TRADITIONAL LOAD-BRAKING METHODS WITHOUT EXTERNAL EQUIPMENT
The techniques for braking of high inertial loads to a stop traditionally involved either Dynamic Braking or DC Injection Braking technology.
This article examines a new load-braking alternative called High-Slip Braking (HSB). We identify the different aspects of HSB, look at what it does, how it works, and how it is different from other braking methods. We also provide examples of "real world" successes, and discuss the new technology's cost effectiveness.
WHAT DOES HSB DO?
High-slip braking allows the stopping of larger inertial loads without the need for expensive and bulky braking options such as Dynamic Braking packages. Inertial loads involve only inertia and friction and given enough time, will tend to stop on their own when power is removed. HSB is most effective in applications involving infrequent stopping of inertial rotating loads where speed control during stopping is not required. Typical applications of this sort include; laundry equipment, centrifuges, large commercial fans, punch presses, blowers and mixers. Do not use HSB on overhauling static loads like; hoists, winches, elevators, product lifters, and similar applications. HSB is applicable only for complete stopping of the load and not as a means of braking for speed changes.
The HSB feature has proven to cut braking times in half without requiring extra equipment. The overall stopping time, however, does depend on the inertia of the load being stopped and the characteristics of the motor. HSB can achieve braking torque of more than 100% of the full motor torque.
