Re: Polaris Ranger EV Sevcon help

Tnx for the reply,

No, both throttle pots swing positive.
What I'm looking for is information to reprogram controller to accept single pot and fs1.

Re: Polaris Ranger EV Sevcon help

Solution for now is using oem Polaris dual throttle. Works perfectly F&R. Why, I have no idea. To use my existing single pot, I used a divide by 2, sending 1/2 voltage to second throttle input. .25v-5v to p23 .12v -2.5v to p22 Defeats the purpose, but runs. Overall a huge success. A Polaris powered ...

Polaris Ranger EV Sevcon help

I have DLD and DCF from a Polaris Ranger to share if someone can help me get reverse to work. My Sevcon tech struck out last night. It should have been plug and play, transplanting the oem controller to a R&T 4wd vehicle, but it won't run in reverse. S6 48v Gen4 Sevcon controller running an 8kw indu...

Yes, I would.
I have files now, so I can clone another, but I paid good money for my s6 controllers.

Re: Sevcon Gen4 model designations?

About 10 of my used gen4 s4 80v are "207".
Will they do the same encoders as my 203s?
All came from e-bikes using Pmac motors.

Re: Induction motor sevcon gen4 issue

I don't have a ranger, but I have the controller and files. S4 and s6 gen 4 controllers. Also 8kw induction motors and big Pmac motors for transaxle mount.
I was hoping to run higher voltage, but the ranger files from s6 48v won't run in an 80v s6.

Re: Induction motor sevcon gen4 issue

More sevcon induction motor questions. What do you suppose Polaris is trying to accomplish with this slip map? Extracted from 2012 Ranger 8kw 48v s6 gen 4. I am using this in another vehicle. Log shows full throttle and torque. Performance is lacking. Less than 300amps under heavy load. 6000rpm limi...

Anyone know what this is for?
It is a firmware file for a Sevcon Gen4.
For what motor type?

Does anyone have UK0328.04 for ct&t E-zone S4 80v?
Will pay or trade?

Re: Induction motor sevcon gen4 issue

No, it's an induction motor with ab sensor. Same motor and programming works fine in s6. Am I wrong to expect it to work with s4 at lower performance? It may be hitting a hard current limit and clipping. I would expect it to lock out in that case. I'm looking for a way to limit torque at low rpm. It...

Induction motor sevcon gen4 issue

8kw induction motor runs fine using s6 80v controller in 2000lb vehicle. Same motor runs great using s4 80v gen4 in <1000lb vehicle. S4 in the heavy vehicle chatters harshly at low speed and high torque demand. I don't know the proper term for this. Cavitation, cogging? Turning the drive profile tor...
