Electric motor thermal protection temperature
When you see the term \"thermal protection\" or \"thermally protected\" used in the description of an electric motor, it refers to a device found within the motor or motor compressor that is designed to prevent dangerous overheating that can cause motor failure. See more This overheating generally occurs when the motor is overloaded, when a bearing seizes up, when something locks the motor shaft and … See more The thermal protector consists of one or more heat-sensing elements built into the motor or motor-compressor, plus an external control … See more A sump pump is a motor for which this scenario often occurs. If a sump pump pumps water filled with debris, pieces of debris may get caught in the impeller and lock the … See more These thermal protectors reset themselves once the motor cools down to a safe operating temperature. There is usually a visible red button located on the wiring side of the motor usually, though not always, located … See more WebElectric motors are the backbone of modern automation. Motors convert electrical energy into mechanical energy, and the resulting motion and torque drives a load. The most effective motor control solution is the variable frequency drive, or adjustable speed drive. Drives vary motor input frequency and voltage to control motor speed and torque.
