摘要： The present invention is organized about the concept of providing an improved pawl brake assembly for use in electromechanical devices such as all electric motors or solenoids. For example, the improved pawl brake assembly (50) may be used for braking the rotor assembly (26) upon de-energization of the motor (2). The pawl brake assembly comprises a pawl arm (52) and a brake portion (56). The pawl brake assembly employs electromagnetic principles to reduce the noise and metal fatigue caused by the undesired excess vibrational motion of a pawl arm when a motor is energized. The novel use of a magnet (80) disposed upon the pawl arm of a pawl brake assembly provides a simple, elegant, and inexpensive solution to the identified noise and metal fatigue problems.
