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 ...

Isolating problems in the control circuitIn 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 ...

Control circuits can be connected directly to the line leads (as shown in the diagram), or can be isolated from the power circuit with a transformer. Lower voltages, such as 120 or 240 V, are used if ...

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 ...

Groomed for use in small-motor control circuits, the HSF series surface-mount, surge resistor exploits a cylindrical design to aid heat dissipation and produce higher surge/pulse capabilities than ...

A "multi-motor EV control circuit" manages and controls the operation of multiple electric motors to deliver precise torque distribution and enhanced traction control.
