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 ...

Q: My 1999 Pontiac Sunfire coupe is doing something something I can't easily explain. The car has 240,000 km on it and it has the stock engine, although I think I bought it with a K filter charger.

Virtually every modern car on the road is equipped with bells, whistles, and sensors designed to let you know when even the slightest thing is wrong with your vehicle. While any driver can appreciate ...

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 ...

• 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 ...
