This will result in an overcurrent through the motor winding. PTC heaters are used in a wide variety of applications across many industries. A large surface area means the element can operate at a lower temperature and still deliver a large amount of heat. PTC stands for "Positive Temperature Coefficient," which is a reference to the resistance that it takes to put enough energy into an object before it starts to feel like it's heating up, then displays an increase in electrical resistance. It would be helpful to have an indicator that shows the user whether the controller is in the initial "constant power" mode or in the "temperature control" mode.

PTC Ceramic Heater High performance self-controlling ceramic heater PTC Thermistor Description: A heating element converts electricity into heat through the process of resistive or Joule heating.Electric current passing through the element encounters resistance, resulting in heating of the element.Unlike the Peltier Effect this process is independent of the direction of current flow. In the PTC heating element, when a resistance of the electrodes per unit length is taken as R E [ohms/m], a unit conduction path length of the PTC heating element is taken as L [m], and. If being able to adjust the temperature is more important than holding a fixed temperature, then a PTC material whose resistance changes smoothly with temperature can be used. So, in a heating element they are designed to produce as much heat per watt of loss in the resistor; in a conventional circuit, they are designed to have low of losses as possible. For telecom . If you can characterize the resistance vs temperature of the heating element, your controller could have a separate mode where it initially limits power on startup until you reach some temperature where you know that the resistance is such that the controller turning full on or 100% duty cycle on your PWM will not draw more power than is acceptable to you.
