Abstract

The present relates to a system comprising a housing, a motor assembly, a printed circuit board (PCB) and a shaft. The motor assembly is located inside the housing. The motor assembly comprises a control for alternatively engaging and disengaging a functionality of the motor assembly. The printed circuit board (PCB) is located inside the housing and defines an aperture for receiving the shaft. The shaft extends through the aperture of the PCB. A first end of the shaft is adapted for actuating the control of the motor assembly. A second end of the shaft extends through an opening in the housing and is adapted for receiving an actuator.

Claims

1. A system comprising:

a housing comprising an opening;

a motor assembly located inside the housing, the motor assembly comprising a control for alternatively engaging and disengaging a functionality of the motor assembly;

a printed circuit board (PCB) located inside the housing and defining an aperture for receiving a shaft, the PCB comprising one or more central processing unit (CPU), one or more memory and an electrical power circuit;

the shaft extending through the aperture of the PCB inside the housing, a first end of the shaft being adapted for actuating the control of the motor assembly, a second end of the shaft extending through the opening in the housing and being adapted for receiving an actuator; and

the PCB being located between the motor assembly and the opening in the housing.

2. The system of claim 1 wherein the system is a Variable Air Volume (VAV) control system.

3. The system of claim 2, wherein the motor assembly controls at least one valve of:

a heating apparatus, a ventilating apparatus, or an air conditioning apparatus.

4. The system of claim 1, wherein the motor assembly transmits one of a torque or an electrical power to a controlled apparatus.

11. The system of claim 1, further comprising the actuator, the actuator being located substantially outside of the housing and being affixed to the shaft.

12. The system of claim 11, wherein pressure applied on the actuator is transmitted via the shaft to the control of the motor assembly and disengages the functionality of the motor assembly.

13. The system of claim 12, wherein releasing pressure applied on the actuator is transmitted via the shaft to the control of the motor assembly and engages the functionality of the motor assembly.

5. A system comprising:

a housing comprising an opening;

a motor assembly located inside the housing, the motor assembly comprising a control for alternatively engaging and disengaging a functionality of the motor assembly;

a printed circuit board (PCB) located inside the housing and defining an aperture for receiving a shaft, the PCB comprising one or more central processing unit (CPU), one or more memory and an electrical power circuit;

the shaft extending through the aperture of the PCB inside the housing, a first end of the shaft being adapted for engaging or disengaging the control of the motor assembly, a second end of the shaft extending through the opening in the housing and being adapted for receiving an actuator;

the actuator being affixed to the shaft; and

the PCB being located between the motor assembly and the opening in the housing.

6. The system of claim 5, wherein a pressure applied on the actuator is transmitted via the shaft to the control of the motor assembly and disengages a functionality of the motor assembly.

7. The system of claim 6, wherein releasing pressure applied on the actuator is transmitted via the shaft to the control of the motor assembly and engages the functionality of the motor assembly.

8. The system of claim 5 wherein the system is a Variable Air Volume (VAV) control system.

9. The system of claim 8, wherein the motor assembly controls at least one valve of:

a heating apparatus, a ventilating apparatus, or an air conditioning apparatus.

10. The system of claim 5, wherein the motor assembly transmits one of a torque or an electrical power to a controlled apparatus.

14. A system comprising:

a housing comprising a front panel, the front panel comprising an opening;

a motor assembly located inside the housing, the motor assembly comprising a control for alternatively engaging and disengaging a functionality of the motor assembly;

a printed circuit board (PCB) located inside the housing and defining an aperture for receiving a shaft, the PCB comprising one or more central processing unit (CPU), one or more memory and an electrical power circuit; and

the shaft extending through the aperture of the PCB inside the housing, a first end of the shaft being adapted for actuating the control of the motor assembly, a second end of the shaft extending through the opening in the front panel of the housing and being adapted for receiving an actuator;

wherein the PCB is located between the motor assembly and the front panel of the housing, and the front panel comprises at least one control for controlling a component of the PCB.

15. The system of claim 14, wherein the at least one control for controlling a component of the PCB comprises a power control button for controlling activation of the electrical power circuit of the PCB.

16. The system of claim 14, wherein the at least one control for controlling a component of the PCB comprises a touchscreen allowing a user to control functionalities implemented by the one or more CPU of the PCB.
