Re: (ET) Field weakening

The Alltrax is fine with an I-5 motor (same as the E20 motor). Just be careful when locating the field wiring in the 4-pin connector on the motor. Pins 1 & 2 are the field and should measure about 18 ohms. Pins 3 & 4 are the internal thermal switch which will measure as a short circuit (zero ohms) and would make the controller very unhappy if hooked up as the field. There is a little ridge on the outside of the plastic housing by pin 1. The field wires may be labeled as #62 and #36.

Thanks for the info. Yes plowing dirt with 10” Brinly. Have a motor from 
an I-5 that I could drop in or is that a bad idea based on the higher motor loads 
going thru the Alltrax?

Maximum power is without any field weakening. Field weakening is used for 
lighter loads at higher speeds.

Being August, I'm assuming that the plowing involved is of dirt? A disc 
plow or similar? With the change in pulley ratio may need to use a lower 
gear when using ground-engaging implements like the plow. ie use LL if not 
already doing so.

Hi,
I updated my E-16 with an Altrax controller. I turned off the field 
weakening as I did not like how sudden it engaged and disengaged. To get 
the speed back up I also installed a .76 ratio cog belt drive as well.

I was doing some plowing and it seemed like the motor was working more 
than it did in the past. In fact it kicked out the main thermal on the 
drive motor. Now my question. Does the motor have more power with field 
weakening enabled or just more speed? I want to come up with the best 
combo when performing high drive motor loads.

Thanks
