Motors differ from other types of loads in one important way: The motor needs much more current to start than to run. This temporary, but significant, inrush current is what complicates motor circuit ...

Thanks to ongoing innovations in technology, electrical engineers' approach to motor protection has changed over the years. The traditional strategy to large AC motor protection (e.g., over 500 hp), ...

Build in a thermal safety margin to handle servomotors that heat up more than theoretical models predict when the torque cranks up. • The relationship between intermittent and continuous torque is ...

ST Micro's Markus Ekler explains the technology and derives thermal loss equations that can be used to support design decisions for stepper motor driver circuits. One constant trend in the automotive ...

Carlo Gavazzi is proud to launch the DMPU Series Motor Protection System. The DMPU is a modular electronic motor protection relay to control, monitor and protect the performance of 3-phase constant or ...

Silicon-ESD, PPTC devices offer built-in protection for consumer electronics' ports and motors. The USB, HDMI, and eSATA ports in our smartphones, tablets, automotive infotainment devices, and other ...

Solid-state relays provide robust solutions for electronic switching in load control applications and hold many advantages over electromechanical relays. New, emerging solid-state relay designs offer ...
