A drive 
is the digital camera that harnesses and regulates the electrical energy delivered to the electric motor. The drive feeds electricity into the motor in varying amounts and at various frequencies, thereby indirectly controlling the motor’s swiftness and torque.
So the the majority of economical choice would be a Three Stage Induction motor followed by a BLDC engine. I’d suggest BLDC ( for its huge market penetration in recent times,simple availability and Electric Drive Motor china easier electronics/control ) or PMSM (Long term magnet synchronous motors )
