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 ...

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 ...

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 ...

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 ...

It is no secret that any equipment that either heats or cools is coming under great scrutiny as governments increasingly legislate efficiency standards. In particular, washing machines, air ...

STMicroelectronics has announced a complete three-phase motor-control development kit (the STM3210B-MCKIT) based on its STM32 Flash microcontroller, which provides all the necessary hardware and ...

Toshiba has launched two sine-wave pulse width modulated (PWM) drive controllers for three-phase brushless DC motors ...

When you get the call, “The motor won’t start,” you’d best have a logical and systematic plan in place to approach the problem. “Easter egging” just doesn’t work unless you happen to be very lucky!

Hardware-Software Solution for Three-Phase BLDC Motor Inverters Enables Greater Than 98 Percent Efficiency, Saves PCB Space and Speeds Time-to-Market Power Integrations’ Motor-Expert™ Suite for ...

Toshiba Electronics Europe GmbH has released two sine-wave PWM drive controllers – TC78B043FNG and TC78B043FTG – for three-phase BLDC motors, which can support surface permanent magnet (SPM) and ...
