This paper presents the system concepts and describes the circuit implementation of several key features. The increasing use of high-current brushless dc (BLDC) three-phase motors puts stringent ...

For IGBTs, the on-state voltage drop is a critical specification to consider. This drop includes both the diode drop across ...

Startup techniques employed to overcome the problem of determining magnet position in BLDC designs. Cost-saving and power-efficiency incentives using sensorless motor drivers. Motor-driver solutions ...

One of the hidden complications of upgrading grain drying and handling systems is providing enough electricity to power the new larger electric motors. Electric motors that are larger than 15 hp ...

While software and other advanced technologies often capture the automation technology spotlight, the fact remains that not much happens in the manufacturing or processing industries without motors.
