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