Question for AL "The Man"

[elalto]

Hi Al,

I have three new servo motors that I hope to use to convert my X3 size mill, problem is I can find no specs on the motors. The motors have the following data on the label:

Model # E660
Part # 0660-04-076
"1/4 HP PWM"

Can you help me out?

Thanks,

Marcos (elalto)

Reliance/ElectroCraft had both Brushed and BLDC motors as E type, I don't show anything for E660 in either unfortunately.
Sometime a OEM number was used when supplied to large purchasers.
Is it Brushed or Brushless?
Al.
