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