Automatic HVAC Air Recirculation Made Easy with Stepper Motors

ثبت نشده
چکیده

This paper highlights the system requirements and operating conditions of automatic air recirculation valves and reviews compatibility of existing actuator types with these requirements. When comparing the available technologies, it becomes clear that air recirculation flap actuators containing a bipolar stepper motor offer key advantages over actuators with other motor types. It is shown how specific bipolar stepper motor drive techniques can contribute to the overall system performance while the total system cost is minimized. The paper elaborates on availability and key features of motor driver integrated circuits that allow advanced control of these novel actuators.

A Novel Vector Control Strategy For Bipolar Stepper Motor

The requirement of precise control in servo applications used in the digital systems led to the development of stepper motors. The precise and zero backlash operation of steppers extended its reach to various position control applications. The lack of requirement of sensors for position control applications was one of the main reasons for preferring stepper motors. Since the stepper motors were...

Application of Solar Thermal Collectors to Improve the Energy Performance of the Fresh Air HVAC Systems

 In the preset study, the performance of a solar assisted heating, ventilation and air conditioning (HVAC) system in an operating theater building was studied. The yearly performances of the existing HVAC system and the system with the added solar collectors were simulated in terms of energy consumption and provided air conditions using a transient system simulation software (TRNSYS). In t...

Nonlinear Adaptive Control of a Permanent Magnet Stepper Motor

This paper considers adaptive position control of a permanent magnet (PM) stepper motor using exact linearization via static state-feedback. Physical outputs are chosen in such a way that the resulting closed-loop system is linearized and decoupled. The objective of the adaptive controller for a PM stepper motor is to achieve output tracking between the motor outputs and prescribed reference si...
