i had a old TECO 4H4018S stepper motor. i couldn't find any info regarding this motor online.
how do i identify this motor?
It has 5 wires (red blue brown yellow white).
I did a resistance test.

red to all colors except brown = 140ohm
blue to all colors except brown = 140ohm
yellow to all colors except brown = 140ohm
white to all colors except brown = 140ohm
only brown to all colors is 70ohm.


thanks

Its a unipolar motor, the brown is a center tap to both phases. (Half the resistance)
Also My understanding is that Teco dont make stepper motors, they badge them.

There is only one wire that you power up, and that is the brown.
The Brown is internally linked to the the centre of each phase.

is there no -ve connection?
