Unfortunately a drive built to run off of line AC will generally be approximately the same amount larger as the size power supply you need. Simply because you've stuck the power supply inside the drive. You could try looking for a smaller supply? Can you combine the power supply with any

For my robotics application, I'm drivnjg 100+ W BLDC motors with a driver that is maybe one square inch. All you need are 6 mosfets and a tiny microcontroller. I have a larger one that handles 50 amp per phase and it is about 6 sq. in. Look at the typical drone, there are four 100+ W BLDC

This is correct to some degree. A motor controller wouldn’t need need the dc-dc controller, isolation transformer, and output diodes and filters, which accounts for about half of the space to my reckoning. Also, high voltage, low amperage motor controllers are usually more compact than their

I'm a little confused, a BLDC motor is still going to need a drive/driver, weather or not it runs at line voltage, that you say you don't have space for. How is that going to help you? Todd Zuercher P. Graham Dunn Inc. 630 Henry Street Dalton, Ohio 44618 Phone: (330)828-2105ext. 2031
