The Blulectric Motor is an item from the RedPower2 mod that is used in devices that require torque. It is not placeable; 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.
