Note: This specialization requires purchase of a hardware kit in order to apply your knowledge and skill with real world tools. The hardware will be used to complete the lab exercises across the four ...

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 ...

This triac-based 220V AC motor speed controller circuit is designed for controlling the speed of small household motors like drill machines. The speed of the motor can be controlled by changing the ...

The circuit switches the MOSFETs, which in turn send current through the legs of the ac motor. A typical high-speed PWM motor-control system uses fast-switching, high-power bipolar transistors, IGBTs ...

The topic of motors and motor control techniques is wide and varied. Part one of this two-part article will cover the principles of alternating-current (AC) motor operation and control. Part two will ...

Got a motor down? No matter how urgent the problem — and motor failure can cause some very urgent problems — always develop a plan of attack before you start repair work. Gather up any background ...

Higher Capabilities for Safety-Rated Control Circuits A truly reliable safety control system must work even when some parts fail. Force-guided relays are unseen components that add another level of ...

Greater use of robots in the world of automation is bringing about higher productivity in manufacturing, as well as lowering costs. To meet those objectives, robots must have faster response times as ...
