hi,
When a negative voltage is applied to the energy converter it rotate counterclock wise and when positve voltage is applied it rotate clockwise
(-23V & 23V).
This is the point thats been causing me concern, it appears that the motor requires to be able to be driven in either direction.
A single power transistor will not be able to drive a motor clockwise and anticlockwise.
Look up 'H bridge' on the web or this forum. This type of bridge will enable the motor to drive either way.
Hope this helps.
If you look at the specification of the motor it need 48V.
Please post the motor spec.
