A drive is the digital camera that harnesses and regulates the electrical energy sent to the electric motor. The drive feeds electrical power into the motor in various Electric Drive Motor amounts and at varying frequencies, thereby indirectly controlling the motor’s speed and torque.

So the most economical choice will be a Three Stage Induction motor followed by a BLDC motor. I would suggest BLDC ( because of its huge market penetration recently,ease of availability and easier electronic devices/control ) or PMSM (Long lasting magnet synchronous motors )
