The ceremonial first post!

I was researching some Motenergy motors and found 2 (ME1114 and ME1012) that are the same size and that I think will suffice for what I'm working on. The only difference I've been able to find is that the ME1114 are newer and have a sin/cos sensor in them rather than the hall sensors that the ME1012 has. Apparently having a sin/cos sensor allows for better rotor positioning and smoother acceleration at low speeds (or so i'm told), however the cheapest ME1114 I could find was still $200-300 more expensive than it's otherwise identical brother. Thoughts? Is it worth it to fork out the extra cash for that sensor configuration? What am I missing?

Thanks!

Welcome!

I believe the ME1114 is very similar to the 2012 Zero S/DS motors. Those motors have proved to be fairly reliable outside of the motor encoder potting.

What am I missing?

The encoder can be an complete arse if it gets wet, Sincos versions of controllers are possibly more expensive.

I ended up going with the newer version that includes the sin/cos sensor. Better safe than sorry I guess! Is it common practice to waterproof your motor specifically in order to protect the sensors and jazz?
