[Davide Gironi] shows us how to implement a sensorless brushless DC motor controller (sensorless BLDC) using an ATmega8 microcontroller. In order to control a BLDC motor you need to know its rotati… ...

This device was designed for use with 12- and 24-V motors. Its dc supply range is 4.5 to 35 V, and output-current capability is 8 A peak. The outputs to the motor winding are derived from the ...

There seems to be some confusion within the industry about the terms “permanent magnet synchronous motors” (PMSMs) and “brushless DC (BLDC) motors”. I’ve talked with several different application ...

The MCP8025 and MCP8026 three-phase BLDC motor gate drivers are both available now for sampling and volume production, in 40-pin, 5x5 mm QFN and 48-pin, 7x7 mm TQFP packages. Pricing starts at $2. ...

Kollmorgen, a subsidiary of Danaher Corp, manufactures the 24V, 300WBLDC (brushless-dc) motor in India. A true BLDC motor, it hasHall-effect sensors that feed back the rotor position to the ...

Engineers who have a firm handle on losses in BLDC motors can better design efficient motors for their specific applications. Brushless DC (BLDC) motors transform electrical power into mechanical ...

A family of modular brushless permanent-magnet motors consists of 75‑mm (2.95-in.) squared motors in three stack lengths. Peak motor torque varies from 250 to 630 Ncm (354 to ...

EPC has come up with a 3-phase BLDC motor drive inverter reference design which operates from an input supply voltage range of 14 V to 60 V and delivers up to 60A output current. This voltage range ...

Think you’ve got what it takes to build a homebrew brushless motor? As [JaycubL] shows us, it turns out that a bldc motor may be living in pieces right under your nose, in scraps that so many… ...
