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.

This application note presents the closed-loop control of a 3-phase brushless direct current (BLDC) motor using a Z8FMC16100 microcontroller. Zilog’s Z8FMC16100 series of microcontrollers are designed ...

Fairchild Semiconductor's China-based Global Power ResourceSM Center (GPRC) has developed a reference design for Brushless DC (BLDC) motor controller applications using SPM® smart power modules, and ...

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 ...

Having reviewed the basics of BLDC motor control in Part 1, the design effort canbegin.. The first quest is to select a microcontroller. Looking in themarketplace there are several microcontrollers ...

The electric motors used in body motor systems are controlled using switches arranged in the shape of the letter “H.” By Arun Vemuri Body motors for movement are key to comfort and convenience in ...

Brushless dc (BLDC) motors offer multiple benefits over other types of dc motors. They’re efficient, reliable, run at high speeds, are compact for their power level, and produce little or no EMI.

Toshiba Electronics has announced the launch of a sensorless control pre-driver IC for brushless DC (BLDC) motors used in industrial and automotive applications. The main applications will include ...

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!
