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 ...

Single-phase and 3-phase AC squirrel cage induction motors need some type of control circuit to initiate a start or stop function. The two types of ladder control circuits commonly used are the 2-wire ...

The DC motor is widely used in the field of servo automation and robotics. The operating principle of an electric motor is based on the interaction of two magnetic fields that attract and repel each ...

Purpose-built platform reduces time, cost, and complexity in developing next-generation PCB Stator motor systems. NEEDHAM, ...

Mechanically actuated automotive systems, such as power steering and fuel and water pumps, are being replaced with systems that utilize electric motor technology. Consequently, the presence of ...

It is often necessary for persons other than licensed electricians to perform minimal electrical work in a commercial or industrial facility. This work must be performed in the same safe manner as all ...

A new 32-bit RISC microcontroller from Renesas Technology America Inc. (www.renesas.com) is designed specifically for controlling electric motors in automotive chassis, safety and hybrid electric ...

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 ...
