Abstract

An elevator system including a hoistway, an elevator component disposed in the hoistway, and a power assembly disposed in the hoistway, the power assembly including a first power component disposed in the hoistway, the first power component including a first power connection, and a second power component operably coupled to the elevator component; wherein the first power component is configured to provide wireless power to the second power component.

Claims (26)

1. An elevator system comprising:

a hoistway;

an elevator component disposed in the hoistway; and

a power assembly disposed in the hoistway, the power assembly comprising:

a first power component disposed in the hoistway, the first power component comprising a first power connection; and

a second power component operably coupled to the elevator component;

wherein the first power component is configured to provide wireless power to the second power component;

a guide rail disposed in the hoistway, the guide rail configured to engage the elevator component and direct the course of travel of the elevator component; and

a safety device operably coupled to the elevator component, the safety device configured to engage the guide rail to stop the elevator component;

wherein the second power component is operably coupled to the safety device.

2. The elevator system of claim 1 , wherein the second power component is configured to connect to the first power component via a direct connection or an indirect connection.

3. The elevator system of claim 1 , wherein the first power component is operably coupled to a power source.

4. The elevator system of claim 1 , wherein the second power component comprises:

a second power connection;

a first power storage device operably coupled to a second power connector;

a safety actuation controller comprising a communication module, the safety actuation controller operably coupled to the first power storage device.

5. The elevator system of claim 1 , wherein the first power component is operably coupled to the guide rail.

6. The elevator system of claim 1 , wherein the elevator component comprises at least one of an elevator car and a counterweight.

7. The elevator system of claim 6 , further comprising an elevator drive configured to impart movement to the elevator car.

8. The elevator system of claim 4 , wherein the communication module is configured to wirelessly exchange safety signals with the elevator controller.

9. The elevator system of claim 4 wherein the second power component further comprises:

an electromagnetic component operably connected to the second power component, wherein the electromagnetic component is configured generate an actuation of the safety device.

10. The elevator system of claim 9 , further comprising:

a magnetic brake disposed adjacent to the electromagnetic component, the magnetic brake configured to move between an engaging position and a non-engaging position based in part on a hold force.

11. The elevator system of claim 9 , wherein the safety actuation controller comprises a communication module, wherein the communication module is configured to wirelessly communicate safety signals.

12. The elevator system of claim 9 , wherein the first power component includes a first power connector and the second power component includes a second power connector configured to engage the first power connector.
