Motion System Options for HVAC Gas Valve Actuators

In HVAC systems that provide heat for enclosed spaces, gas and liquid flow must be controlled and metered accurately using sensing and modulating elements such as flow control valves or isolation valves. Some control valves are opened and closed manually at the valve stem, while electronic valves incorporate an actuator to move the stem with control from a motor and drive system. Designers have three motor types to choose from, depending on the application requirements. Here’s a summary of the motion system options:

Improve Thermal Performance for Ironless Brush DC and Brushless DC Motors

Electric motor manufacturers must ensure that a motor’s instant internal temperature never exceeds its various components’ maximum allowable temperature. Depending on the design of the motor and the materials used, thermal phenomena will dictate the motor’s performance. Motor designers typically have two options to enhance motor performance without overheating and damaging its components: increase power conversion efficiency by generating less heat for a given mechanical power output or improve the motor's cooling capability through heat dissipation.
