Running 72V motor at 60V

[garolittle]

Other than having fewer RPMS, are there any problems with running the 72 V motor and motor controller (in the link below) at 60 V? It seems like this would also reduce heat since the motor would be under-volted.

Thanks for any comments. Gary

I believe your assumptions would be correct about running a 72V motor @ 60V
...but not a speed controller
(unless it's programmable)

Because a 72V speed controller should have a low voltage cut-off of ~63V
…& if it did work you wouldn't have much range

Thank you sir. I really appreciate the feedback. I hope you’ve been doing well. Stay safe and healthy.
