A drive is the digital camera that harnesses and controls the electrical energy delivered to the electric motor. The drive feeds electricity into the motor in various amounts and at varying frequencies, thereby indirectly managing the motor's speed and torque.
So the the majority of economical choice would be a Three Stage Induction motor followed by a BLDC engine. I would suggest BLDC ( for its huge 
market penetration in recent times,simple availability and easier electronic devices/control ) or PMSM (Long lasting Electric Drive Motor china magnet synchronous motors )
