Testing a DC PM motor
)'m new to this community and appreciate any help you can give me. I am a hobbiest and recently purchased a Pacific Scientific motor (SR 3624-5107) to replace the motor in my lathe. I'd like to test it before putting it in to service. I connected it to a 12V battery and it runs smooth and quiet. I then connected it to the controller (Dart 125DV-C-K) and ran it up to 60v. Motor turned around 2000 rpm drawing about 1 amp, albeit under no load condition. I put an ohmmeter across the armature and it reads ~1 ohm. I turned the shaft slowly and it reads about the same throughout a full revolution. Is this too low?
Thanks, Dick White, Cary NC
