A linear propulsion assembly imparts a force upon an elevator car traveling in a hoistway, and includes primary and secondary portions, and an active damper system. The primary portion mounts to one of the car and the hoistway, and includes electric coils. The secondary portion mounts to the other of the car and the hoistway, and includes a rail and magnets engaged to the rail for moving the secondary portion with respect to the primary portion. The damper system contacts the rail for damping rail vibration, and includes a sensor, a controller, a force actuator, and an enclosure. The sensor sends a signal, in response to vibration in the rail, to the controller. The actuator generates a force in response to a control signal from the controller to reduce the vibration in the rail. The controller and the actuator are disposed in the enclosure which is embedded in the rail.
