| Can this motor be used with a speed controller? |

| NormanV:
The motor has a built in speed switch with a off position between each speed so I imagine that it would be simple to wire it up to a VFD, as Rob suggested, without any problem. |
| Noitoen:
A 2 speed motor's winding is a compromise to be able to split the poles in half to achieve the 2 different speeds. Usually the best winding is the low speed one. Connect this winding to the VFD and it will run ok. |

Worth looking into!

| John Stevenson:
Short answer is no because one set of windings needs 440v, can't be delta'd as it uses two sets on winding in delta for the other speed. To use this you need either a Transwave, a rotary converter or one of those shitty inverters that have been bodged to output 440v |
| NormanV:
Thanks for the advice, it sounds as if it is not worth the trouble. Another motor won't be too expensive. |
