Customized and Reliable Stepper Motors Address HVAC Damper Application Extremes

If you have to regulate HVAC system airflow on a constant basis, you’ll need automatic dampers with electric or pneumatic motors that can be controlled by a thermostat or building automation system. When designing an external mount electric damper actuator for an HVAC system, it’s important to review considerations in order to create the best motor-damper combination.

When evaluating a miniature motor to pair with an actuator, keep in mind that it may need to be customized. Ask yourself the following questions:

Stepper Motors for Medical Applications

Stepper Motors Provide the Dynamic Performance Your Medical Application Requires

A stepper motor is an electromechanical device that converts electrical pulses into discrete mechanical movements and therefore can be operated directly from a pulse train generator or a microprocessor. Stepper motors can work in an open loop, the controller used to drive the motor can keep track of the number of steps executed and knows the mechanical position of the shaft. Stepper geared motor have very fine resolutions (< 0.1 degrees) allowing precise metering for pump applications and maintain a position without current because of their inherent detent torque. Excellent dynamic characteristics allow quick starts and stops.
