In the first installment of this series, "Calculating a practical hotspot safety margin", we discussed how two-parameter thermal models assume that the entire motor, including windings, exhibits one ...

As automakers shift toward connected, hybrid, and electric powertrains, the demand for intelligent engine management systems ...

• The thermal models that servomotor manufacturers provide may not hold for brief periods of superhigh torque. • More accurate thermal models for periods of high performance use equations with more ...

As previously mentioned, the feedback sensors include position sensors to track the rotor’s location, current sensors to measure the motor phase currents, voltage sensors to monitor the DC bus voltage ...

Whats wrong?: The engine coolant temperature sensor may be cracked. This could cause the enging coolant temperature warning light to come on inadvertently and in rare cases may cause engine operating ...

So your car’s temperature gauge is acting up, or not working at all, and you want to fix it? Good for you. Your car’s engine temperature is vital to its operation, and a properly-operating gauge is a ...

Imagine a turbocharger trying to pressurize a carburetor with its small venturis and finicky floats and you can get some idea why electronic fuel injection opened the door to big boost, big power, big ...
