The Blulectric Motor is an item from the RedPower2 mod that is used in devices that require torque. It is not placeable, rather it is an intermediary crafting item used to make Frame Motors, Disk Drives, and Pumps (RedPower).
A Diamond Drawplate is required to craft Fine Copper Wire, which is a starting ingredient for the Blulectric Motor. The Drawplate requires nine Diamonds (Diamond Block) for crafting, so this is a mid to late-game item and can be expensive, depending on how much use you get out of it.
The approximate EMC cost for raw materials, excluding the Diamond Drawplate, is 4520 EMC.
