BRUSHLESS DC MOTORS
BRUSHLESS DC MOTORS
(OP)
I would like to know from anyone that has hands on experience with the brushless DC drives.If you have used these motors,How reliable are they?
What type of system was it used on?Pump,Blower,Conveyor?
Did you use anything with HP rates of 200 to 400 HP ?
Thank you all for help.

using it for a pump appl
no problems
brushless DC is the way to go

Sync motors may or may not have brushes.You are right about the others.As for the Brushless DC I was refering to is a motor where the rotating element has magnets and the Stator (in this case a field) has the windings.These motors are powered from Inverters not much different that any VFD applic.Th Inverter action provides the DC needed to power motor.As I understand from the literature,they have speed/torque curve characteristics superior to FluxVector Drives.I tried a website for one manufacturer and I was intrigued by the technology.We have most of the other motor types made but none like these.
Thank you Servocam (try POWERTEC website)

The application where we used the 400HP was also Powertec. Have had mixed success with the smaller drives, but little problem with the motors. For variable speed, high torque applications they are nice. The efficiency is good also due to the PM rotor providing the required magnetization.
