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. BridgeSwitch ICs are priced starting ...

This paper presents the system concepts and describes the circuit implementation of several key features. The increasing use of high-current brushless dc (BLDC) three-phase motors puts stringent ...

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 ...

BridgeSwitch ICs provide a motor current output signal that maps the current passing through the low-side FREDFET. An internal sense-FET provides lossless current sensing. The solution is suitable for ...

This solid-state thyristor (SCR) switch circuit is perhaps the simplest means of reversing a 3 phase motor. “Static” is a catch-all term that essentially means without moving (mechanical) contacts ...

Power Integrations’ updated Motor-Expert Suite now features three-phase field-oriented control (FOC) software, including a reconstruction algorithm that uses the phase-shifted trigonometric ...
