Solid state brakes work by electronically stopping a load. They work by injecting a specified DC current amount into an AC motor which has three phases. The automatic braking controller can be adjusted to the needs of stopping a load fast, time and time again, even during situations when the conditions of any given load may change due to a variety of factors. Solid state brakes can increase productivity, enhance safety, and provide maintenance free operation on a variety of motors. Solid state brakes come in different sizes based on amperage and the application they will be used for.
