What causes excessive heat in a motor?
The most common causes of overheating include: An unsuitable motor: Motors come in a range of sizes. The wrong voltage supply: Too many volts or too few volts can be damaging to a motor. When your motor doesn’t have the right voltage support, it needs to work harder to perform, which causes parts to overheat.
Can a small space heater cause a motor to fail?
Some motor manufacturers use metal or ceramic cartridge heaters for this purpose. Since such heaters are small due to space limit, they must operate at a high surface watt density and consequently high temperature. The high temperature causes rapid heater failure, often within the first year.
What happens when a car heater motor stops?
When this heater motor stops one of three things has happened the electrical supply has quit, the motor has burned out or the system ground has failed. A sign that the motor is going bad is when the system is on and the car hits a bump and the motor will start to work.
Why does my blower fan not work on high?
Blower Fan Works on High Only This is a classic blower motor resistor problem which is common on older cars and trucks that use manual fan speed switch controls. This problem will also occur on climate control systems when the speed controller has burned out omitting full power to the blower motor. This can also occur with the ignition key off.
What should the temperature be in a motor space heater?
We also supply various temperature sensors for motor protection, e.g. film pt100, three phase thermistor etc. Feel free to contact us if you have such demand. Condensation problem in motors can be solved by maintaining motor winding temperature 5-10°C above the surrounding air temperature.
What happens if the blower motor only works on high speed?
In other designs, the failure of 1 resistor means you lose only one speed. However, most car makers bypass the blower motor resistor completely when you move the fan speed switch to high. If your blower only operates on its highest speed, chances are you have the series type of blower motor resistor. This is the most common failure mode.
What are the symptoms of a bad heater motor resistor?
Symptoms of a Bad or Failing Heater Blower Motor Resistor 1 Blower motor stuck on one speed A common symptom of a faulty blower motor resistor is a blower motor that is stuck on… 2 Blower motor does not work on certain settings Another common symptom of a faulty blower motor resistor is a a blower… 3 No air from the vehicle’s vents More
