A drive is the digital camera that harnesses and handles the electrical energy sent 
to the Electric Drive Motor engine. The drive feeds electricity in to the motor in different amounts and at various frequencies, thereby indirectly managing the motor’s rate and torque.
So the most economical choice would be a Three Phase Induction motor followed by a BLDC electric motor. I would suggest BLDC ( for its huge market penetration recently,simple availability and easier electronics/control ) or PMSM (Long term magnet synchronous motors )
