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