A drive is the digital camera that 
harnesses and handles the electrical energy delivered to the electric motor. The drive feeds electrical power into the motor in different amounts and at varying frequencies, thereby indirectly controlling the motor’s rate and torque.
So the many economical choice will be a Three Stage Induction motor accompanied by a BLDC motor. I would suggest BLDC ( for its huge market Electric Drive Motor china penetration recently,simple availability and easier electronics/control ) or PMSM (Long lasting magnet synchronous motors )
