A drive is the electronic device that harnesses and settings the electrical energy sent to the engine. The drive feeds electricity in to the motor in Electric Drive Motor china different amounts and at varying frequencies, thereby indirectly controlling the motor’s quickness and torque.
So the most economical choice will be a Three Phase Induction motor followed by a BLDC engine. I’d suggest BLDC ( because of its huge market penetration in recent times,ease of availability and easier 
electronic devices/control ) or PMSM (Permanent magnet synchronous motors )
