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 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 ...

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 ...

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 ...

The new A3930 and A3931 from Allegro MicroSystems Europe are automotive-grade motor controller integrated circuits with built-in commutation logic to lessen the burden on the system microprocessor, ...
