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 ...

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 ...

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 ...

Improving the energy efficiency of today's appliances depends on precisely controlling the speed and torque of three-phase motors based on various types of feedback. Fortunately, specialized MCU-based ...

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 ...

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 ...

Sanken’s inverter power modules for motor control are available from Solid State Supplies. The SCM1110MF inverter power module (IPM) consists of the necessary power elements needed to configure the ...
