To achieve energy efficiency, ceiling fans and ventilation fans are moving from simple alternate-current (AC) induction motors to brushless direct-current (DC) motors (BLDC). An AC-operated BLDC motor ...

In my previous article, I described the four most common methods for motor and pump control: input voltage, input voltage pulse-width modulation (PWM), external PWM, and 0–5V DC analog speed input.

Reference platforms are powerful yet simple-to-use development tools built around leading-edge microcontrollers whose feature sets and performance characteristics are optimized for use as motor ...

Power Integrations created Motor-Expert 2.0 with the design engineer’s needs in mind. The new tool reduces the cost and complexity of BLDC drive design and works with the newly released three-phase ...

Withclosed loop speed control, the fan controller ensures that the fan isrunning at the desired speed by measuring the actual speed and adjustingthe duty cycle accordingly. Here the host specifies the ...

This article describes ongoing internal project activities at eInfochips in the control systems domain for applications in motor and engine controls aimed for aerospace and automotive segments.

A line of brushless DC (BLDC) motor control ICs contain 115 Vac and 230 Vac devices that integrate six IGBT bridges for fractional and subfractional HP BLDC motors. With complementing bridge drivers, ...
