How to calculate suitable dummy load for a power-supply? PTC thermistors are resistors with a positive temperature coefficient, which means that the resistance increases with increasing temperature. May 1, 2018 at 22:01 . When a motor is overloaded or rotation of a motor is stopped (locked), an overcurrent flows through the motor. Fan heaters are used where the heat needs to be transferred to multiple sites or outlets. Resistors usually aren't as heatproof. Such PTC ceramic heating elements are often called "stones". How do you ensure that a red herring doesn't violate Chekhov's gun? In addition, the total current will decrease, so there will be less Joule heating during operation. PTC thermistor, in case of continuing overcurrent, will trip its resistance value by self-heating, reduce the output current and thereby prevent driver circuit damage. A resistor and a heating element are indeed the same thing, just designed for different jobs. Inverters are used to control the speed of induction motors. Riedon's versatile, compact self-regulating heaters feature PTC technology that automatically adjusts the resistance of the heater to continuously maintain the prescribed temperature range.
