Remove the power, and it stops. But there is a condition in between where power is applied but the motor is not moving. This is a motor that is at stall. In this state, with power applied, it is very much a live motor; just because it isn’t turning doesn’t mean current isn’t flowing through the windings - actually just the opposite. At stall, an excess of current is flowing, heating up the motor coils; if stall conditions are maintained, or frequently repeated, these stresses can quickly add up to trouble.

However, selecting the motor is rarely straightforward. Motor technologies all have characteristics that can impact a design in different ways, and  will determine whether you choose a brushless DC, coreless DC or stepper motor. Here are some key considerations to help you choose an optimal motor for your application.

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.

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.
