A drive is 
the Electric Drive Motor china electronic device that harnesses and regulates the electrical energy delivered to the electric motor. The drive feeds electricity in to the motor in various amounts and at varying frequencies, thereby indirectly controlling the motor’s quickness and torque.
So the many economical choice will be a Three Stage Induction motor followed by a BLDC engine. I’d suggest BLDC ( for its huge marketplace penetration in recent times,simple availability and easier electronic devices/control ) or PMSM (Permanent magnet synchronous motors )
