A drive is the electronic device that Electric Drive Motor china harnesses and handles the electrical energy delivered to the motor. The drive feeds electricity in to the motor in varying amounts and at different frequencies, thereby indirectly controlling the motor’s speed and torque.
So the most economical choice would be a Three Stage Induction motor followed by a BLDC electric motor. I would suggest BLDC ( because of its huge market penetration recently,simple availability and 
easier electronic devices/control ) or PMSM (Permanent magnet synchronous motors )
