overspeed governor (OSG)
An Overspeed Governor (OSG) is a safety device that is commonly used in mechanical systems, particularly in elevators and cranes. Its purpose is to prevent the system from operating at speeds that exceed safe levels, thus protecting the users and preventing damage to the equipment.
-
The OSG works by monitoring the speed of the system and activating a set of brakes or other mechanisms when the speed exceeds a predetermined threshold. The threshold speed is typically set based on the design specifications of the system and the maximum safe operating speed.
-
In elevators, for example, the OSG may be integrated into the elevator motor or drive system and activate the brakes if the elevator car begins to move too quickly. This can be caused by factors such as a malfunctioning motor or control system, or by the weight of the elevator car and its occupants exceeding the maximum safe limit.
