In Part 1 of this two-part series, we presented a 3-phase, 480VAC motor circuit with its associated controls (Figure). We stepped through a logical, systematic approach to troubleshoot the main power ...

When you get the call, “The motor won’t start,” you’d best have a logical and systematic plan in place to approach the problem. “Easter egging” just doesn’t work unless you happen to be very lucky!

Electric motors, which convert electrical energy into mechanical energy, play an essential role in a variety of industrial and robotics applications. Given that electric motors account for ...

Relays, Contactors, and Motor Starters provides an overview of the primary components involved in electric motor control. Relays are electrical switches that control a circuit. When activated by ...

In the first part of this electrical troubleshooting series, we discussed how a consistent approach to electrical troubleshooting can help HVAC technicians get a comprehensive assessment of what is ...

Figure 1: Existence of gap junctions between V2a interneurons and motor neurons. Figure 2: Motor neurons control the strength of synaptic transmission and the firing threshold of V2a interneurons.

This quick reference guide describes TE Circuit Protection’s products for automotive applications. These circuit protection devices help provide protection for overcurrent, overvoltage, and PCB trace ...

As with internal-combustion vehicles, the advantages of all-wheel drive for electric vehicles have been obvious from the start as has been the potential to provide multiple motors, ideally one for ...
