Motor Thermal Protector Motor is a very wide range of mechanical and electrical equipment, work in all walks of life often used. If you do not take protective measures on the motor, it may cause a safety accident, motor-driven electrical hazards in use may present a risk of electric shock and a fire hazard. What Is The Motor Thermal Protector Motor thermal protector is a bimetallic superheat protector, is the thermal protection device for the normal operation of the motor. In Ya Xun, to provide a full range of motor thermal protection, such as: DC, single-phase, three-phase, low-voltage motor, high-voltage motor. There are many reasons for motor overheating, such as running overload, selection is not appropriate, cooling failure, lack of monitoring and necessary maintenance leading to premature aging of insulation. The motor in the run-time will produce losses, these losses on the one hand to reduce the efficiency of the motor, on the other hand the loss turns into a motor heating, so that the motor winding temperature increases. The life of the winding insulation material is related to its operating temperature. The temperature is too high, the insulation material will accelerate aging, so that a significant reduction in insulation performance, significantly shorten the life of the motor, even the risk of fire and electric shock hazard. Therefore, the purpose of motor overheating protection, mainly in the design, manufacture, installation and use of motor protection measures, when the motor is operating under certain load and heat dissipation conditions, the temperature of the winding does not exceed the allowable value of the standard.
