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 ...

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 new three-phase motor control code and Motor-Expert 2.0 tool are offered as part of the Motor-Expert Suite under a free license for use with BridgeSwitch ICs.

The on-chip commutation logic consists of a decoder and state machine which together read the inputs of three Hall sensor inputs (or I/O signals from a microprocessor). The IC then outputs the correct ...

We will describe the implementation of an open loop, V/Hz control algorithm to run an arbitrary split-phase induction motor. The algorithm is implemented using International Rectifier's IRMCF341 ...

The new three-phase motor control code and Motor-Expert 2.0 tool are offered as part of the Motor-Expert Suite under a free license for use with BridgeSwitch ICs. BridgeSwitch ICs are priced starting ...
