Brushless controller and minimum motor speed

8 years 9 months ago #29526139 by kab
What is the \"reasonably\" minimum speed that the BL controller may ask a BL motor to perform?

Would 10 RPM be too low?

In other words, Is the motor power (in Newtons) affected by the speed? Or (besides inertia) is the motor able to provide the same mechanical power at 10 or 1000 RPM? (per rotation of course)

Thanks

This very much depends on your motor. The higher the number poles, the slower you can make it turn. We\'ve have a 23 pole-pairs hub motor rotate at nearly 1 rpm.

Hi - thanks for your answer, I\'m back in (brushless) business.

Any of the Roboteq Brushless controller would fit, since I\'m looking after
- 50 to 500 RPM (depends on motor)
- 12 V in
- 1~5A max
- Holding torque 0.5+ N/m
- Hall sensor

Prior to order the Roboteq controller, my concern is more related to how to find a brushless motor that fits (after googling for a while...)

Could you recommend / point to a site that sells that kind of motor (per the specs above). Thanks.
