  2. How do I purshase one HB3GL-A model wheel?
    I love the wheel but don’t see a purchase link. Please let me know. Thank you!

    • Hi Charles,

      This motor is not listed on our webstore yet. Please contact us for buying.

  3. Can 3″ hub motor be made for 18 volts 150 watt and 4 Nm torque at lower top speed 700-900 rpm? I want to use 2 motors for small combat robot, not skateboard.

  4. Hi,
    How slowly rotating can this motor be controlled to be?
    I have some application need 0.8m/s speed, is it possible for these motors work at such low speed?
    thank you so much!

    • the max speed 20km/h. For the lower speed controller, it depends on your controller.

  5. Could you recommend a dual motor controller to run two of them on an électric skateboard?

  6. Hi,

    Do you have the power curve of this motor with 24V and 48V batteries ?

    Best regards,

    • it is not available yet. our testing motor can not do the test for this motor.

      • Thanks for your reply.
        I would like to use it with a 48V battery. Is it possible ? In the description, it is written “We can make this motor 12v,24v or 36v version” and then “Rated voltage: 24-48 v”
        What max current must be the controler ? 48V 12A is too much ?

        Can you confirm the no load speed of 1850RPM under 48V and 0.42A ? Just before, it is written “speed 2800rpm”.

        Thanks.

        • if you need 48v, we have to customize the motor as per your request. I suggest you buy a current motor for testing.

          • OK, I will buy a current motor for testing. Which specifications has this current motor ? 36v version, power 150w and speed 2800rpm ?

  7. Hello.

    What is the kv rating of this motor please?

    Is the outer wheel 75mm or 70mm diametre?
    Drawing shows 70mm but title says 75mm (3″)

    Thanks for your reply.

      • And is it possible to have it with 75mm outer wheel diameter?

        Any info about the kv rating ?

        Thanks a lot.

        • Currenly only 70mm diameter, for the KV, I will check with our engineer and then email you.

          • Is it the same M12 bolt going through the entire wheel? Is it possible to remove it and mount a roller bearing 8mm inside diameter instead?
            Actually I would like to mount it on a electric skateboard.

            Thanks for help
