The document summarizes key features of electromagnetic brakes and torque limiters manufactured by EIDE. An FAE/M electromagnetic brake uses a disk that reacts to springs to directly brake an element, and is de-energized when tension is applied. An LPPSS torque limiter is designed to absorb overloads and maintain synchronism during work. It can include a microcontact breaker to electrically stop transmission if synchronism is lost, detecting increased torque before loss of synchronism through its characteristic curve. EIDE is located in Castellar del Vallés, Barcelona, Spain.
