I am computer programmer and have little experience in elctrical engineering. I am working on a project that uses a BLDC motor with the specifications given below. I would really appreciate some advice on whether Odrive S1 or Odrive Pro is suitable with this motor. I feel like Odrive S1 is sufficient but I want to be sure before I make the purchase.
Typically yes I would say the S1 would be fine, however two things to note:
The maximum modulation depth is 78%, so your motor will only have a top speed roughly 78% of what you expect (e.g. at 48V it’ll be 95*48*.78 = 3556 RPM vs 95*48 = 4560 RPM with the ODrive Pro)
The 12*4.2=50.4V maximum of 12S lipo packs is very close to the absolute max nominal bus voltage of 50.5V – the S1 was designed with 12S packs in mind, however you’ll have to be very careful with inrush current – when you plug the battery into the S1, you can cause a voltage spike due to the large amount of capacitance in the S1, so you should use antispark connectors or a BMS with soft-start/precharge capability.
As long as both of these things are noted, I don’t think there’s an issue with the S1! I’ve personally used it quite a bit with 12S packs with no issues
