Re: Help Finding Drive/Controller

The datasheet says the rated current is 10A and the resistance is 0.23 ohms, per phase. However, from other information on the datasheet, I think that assumes parallel connection. As you have the 8-wire version, you could use series connection instead, which would bring the rated current down to 5A, the phase resistance up to 0.92 ohms and the static coil voltage to 4.6V. That is within the range of the low-cost TB6600-based drivers you find on eBay. You would need a power supply of between 24 and 48V depending on how fast you want to spin the motor and how high the load will be.

Please note, I have not used these drivers, so I don't know how good they are or how much additional cooling they need to run up to their 5A rated current (some of those drivers claim only 4A). However, unless you need the maximum torque, you can (and should) run them well below their rated current anyway, perhaps at 3A or 3,5A.

For really high speeds and/or loads, you would need a driver capable of higher voltage operation, up to the 120V rating of the motor.
