A drive is the electronic device that harnesses and controls the electrical energy sent to the motor. The drive feeds electrical power in to the motor in various Electric Drive Motor china amounts and at different frequencies, thereby indirectly controlling the motor’s velocity and torque.
So the most economical choice will be a Three Stage Induction motor accompanied by a BLDC electric motor. I would suggest BLDC 
( because of its huge marketplace penetration recently,ease of availability and easier electronic devices/control ) or PMSM (Permanent magnet synchronous motors )
