Publication number: 20150122589Abstract: An elevator system is provided that includes an elevator car (12), a counterweight (18), a load bearing flexible member, a motor have a drive, and an elevator control system (22). The car and counterweight are operable to be translated within a hoistway. The load bearing flexible member extends between the elevator car and the counterweight. The motor is operable to move the load bearing member and thereby drive the elevator car and counterweight within the hoistway. The elevator motor and drive are configured to selectively produce regenerative power. The elevator control system includes a power manager unit (24) and a power storage device (26). The power storage device includes a supercapacitor unit (32) and a battery unit (34). The power manager unit is operable to selectively manage the flow of power between the power storage device and the motor drive, and the flow of regenerative power from the motor drive to the power storage device (26).Type: ApplicationFiled: June 1, 2012Publication date: May 7, 2015Inventors: Carlo Mezzadri, Gianluca Foschini, Carlo Colombari

Patent number: 9022178Abstract: An elevator system (20) includes a propulsion power assembly (38) with a power rating below that required to move a fully loaded elevator car (22) using a contract or design motion profile. One example propulsion power assembly (38) uses more than one motion profile based upon existing load conditions. One example uses a first motion profile including a first power parameter limit for load conditions at or below a selected load threshold that is less than a maximum load capacity of the car (22). The propulsion power assembly (38) uses a second motion profile with a lower power parameter limit for other load conditions. In one example, electrical current is the power parameter selected as a decision parameter dictating which profile to select based on an existing load. Another example propulsion power assembly (38) selects at least one of a speed limit or an electrical current limit based on an existing load and maintains a speed to stay within the selected limit.Type: GrantFiled: October 14, 2004Date of Patent: May 5, 2015Assignee: Otis Elevator CompanyInventors: Gianluca Foschini, Sandro Bonfiglioli, Leonida Lorquando, Ronnie Thebeau, Sally Mahoney

Patent number: 5636652Abstract: A transition valve for a hydraulic elevator includes a block, a spool, an actuator, and an end cap. The actuator may be either a solenoid type actuator or an electric motor type actuator. The end cap includes an opening permitting engagement between the actuator and the spool. In a particular embodiment, the actuator is an electric motor engaged with the spool via a crank and arm. This arrangement translates the rotational motion of the motor into linear motion of the spool with a sine curve profile.Type: GrantFiled: February 28, 1995Date of Patent: June 10, 1997Assignee: Otis Elevator CompanyInventors: Renzo Toschi, Gianluca Foschini

Patent number: 5603390Abstract: A control system for controlling the motion of a hydraulic elevator calculates a deceleration distance based upon the elevator velocity and begins the deceleration phase of the elevator motion upon the elevator reaching the calculated distance from the landing. In a particular embodiment, the control system includes a hydraulic valve, a space encoder, and a controller. The space encoder produces velocity and position measurements. The controller uses the velocity inputs to determine the deceleration distance and, upon the elevator car 14 reaching the calculated distance from the landing as measured by the position inputs from the space encoder, commands the hydraulic valve to actuate and begin the deceleration phase. In an alternate embodiment, an interface unit connected between the controller and the hydraulic valve calculates a delay between the deceleration command based upon a predetermined distance and the calculated deceleration distance based upon car velocity.Type: GrantFiled: April 28, 1995Date of Patent: February 18, 1997Assignee: Otis Elevator CompanyInventors: Gianluca Foschini, Renzo Toschi
