The elevator has a linear motor-counterweight assembly which provides the driving power for moving the elevator car. The linear motor is a flat linear motor which runs on a flat strip of steel which is partially coated with a layer of aluminum, copper or the like conductor. The side margins of the steel strip are not coated with the conductor metal, and serve as bearing surfaces for the guide rollers on the counterweight. The counterweight has modular brakes mounted on it which engage the margins of the steel strip to control movement of the counterweight and elevator car. The brakes are electromechanical brakes which are silenced for use in the elevator environment. The counterweight may also have safety gears mounted thereon which also act upon the margins of the steel strip for emergency braking of the counterweight.
