E-T-A Circuit Breakers has introduced a PCB-mounting relay designed to prevent three-phase motors from overheating or burning out, by disconnecting all three phases simultaneously. The E-T-A 3620 ...

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 ...

Solid State Relays (SSRs) and Solid State Contactors (SSCs) are ideally suited for controlling dynamic loads such as motors, particularly where frequent or multiple start/stop cycles are required in ...

Safety is a major concern in a good many motor-driven applications. This is true in industrial applications where motion starts when power is applied and especially true when power is restored after ...

Rockwell Automation has developed a device that provides Ethernet/IP and Web communications for motor overload relays at a cost of around £20. The Allen-Bradley 193-ENT module can send motor ...

Hybrid relays combine a mechanical switch with a solid-state switch, and they are set up in parallel to control a single load ...

The circuit in this Idea for Design provides three levels of speed control for a dc motor using a PC’s parallel port (LPT1). A C++ program performs the control functions by allowing the signals from ...

This is a simple and very effective project circuit which helps to control the speed of a DC motor using pwm and microcontroller. In many applications, it is important to control the speed of DC motor ...

The German car manufacturer BMW recently announced that due to potential short circuit hazards associated with the starter motor and related components, it will recall over 330,000 cars globally. This ...
