Can Brushless DC motor work out without controller?
Can Brushless DC motor work out without controller?
(OP)
Can anyone tell me about brushless DC pump motor if it is possible to use Brushless DC pump and get DC power directly from battery(use transformer to get AC to DC into Battery for charging as power source) maybe I dont need use inverter anymore, is that possible? I heard that Brushless DC pump must work with a controller to start up? a BLDC pump + a controller would be cheaper than a normal AC pump + a inverter? thank you.

And BLDC pump + a controller would be expensive
cheaperthan a normal AC pump + a inverter as well.RE: Can Brushless DC motor work out without controller?

Thank you.

If we can assume that the internal inverter will age and die at about the same rate as an external inverter or a VFD, then the customer is choosing to regularly replace an entire expensive motor instead of a cheap VFD or external inverter.
On balance, by doing that, they also get a new set of bearings and a new motor well before their individual end of life by doing that. Maybe it makes the customer feel better.
You are in a better position than we are to gauge whether the customer is acting out of ignorance or caution in this matter.
