ABSTRACT:
A ropeless linear motor elevator system includes linear motor coils disposed along a guide rail for guiding an elevator car. A linear motor propulsion unit (14) including an operating bar movable relative to the car is mounted on the car for generating a car propulsion force in cooperation with the linear motor coils. The elevator car has mounted thereon a brake unit including a brake shoe engageable with the rail to stop the car and biasing member for urging the brake shoe toward the rail. The operating bar of the propulsion unit is movable between a first position in which the brake shoe engages the rail against the action of the biasing member and a second position in which the brake shoe is released from the rail by the action of the biasing member in response to a propulsion force acting on the propulsion unit.
