A drive is the digital camera that harnesses and controls the Electric Drive Motor china electrical 
energy sent to the engine. The drive feeds electrical power in to the motor in different amounts and at various frequencies, thereby indirectly managing the motor’s quickness and torque.
So the most economical choice will be a Three Phase Induction motor accompanied by a BLDC engine. I’d suggest BLDC ( for its huge marketplace penetration recently,simple availability and easier electronic devices/control ) or PMSM (Long lasting magnet synchronous motors )
