Re: Sepex Motors explained for dummies (like me) by JohnnieB

The DCS is the only sepex drive that I know of that didn't have a speed sensor (There may be others, but I'm not aware of them if there are) and the Alltrax DCX controller was designed to be a plug-n-play replacement for the stock DCS controller (Curtis 1206SX - which had some issues that were corrected in the DCX). A DCS had a higher top speed with a DCX controller than it had with a stock DCS controller. One reason was because it had a user selectable "Turbo" mode that further reduced the field amps when specific conditions are met. (Below is a cut and paste from the Controller-Pro manual) Quote:
I ran my PDS cart with a DCX controller and an adapter kluge and no speed sensor and know my motor got really hot when I ran at top speed. I eventually exploded my stock PDS motor and replaced it with the D&D motor I'm running now, which I ran with a DCX until the XCT was introduced in 2015. The Field Weakening Limitations Map (attached) for my ES-76-51 motor indicates a minimum of 3A for any armature amp flow below 100A, but I have data logs from the XCT showing field amps of 1A and less, so I suspect the Alltrax guys might have played a little fast and loose with motor manufacturer's recommendations with the DCX field maps also. I can see both sides technically. The motor manufacturer want to keep the field amps high so the motor runs cooler and the controller manufacturer wants to reduce the field amps more so the cart will go faster with their controller installed. FWIW: The term "Field Map" might a shortening of the term "Field Weakening Limitations Map" that some motor manufacturers use. |
