A drive is the electronic device that Electric Drive Motor china harnesses and settings the electrical energy sent to the motor. The drive feeds electricity into the motor in different amounts and at varying frequencies, thereby indirectly managing the motor's velocity and torque.
So the many economical choice will be a Three Phase Induction motor followed by a BLDC engine. I would suggest BLDC ( for its huge marketplace penetration recently,ease of availability and easier consumer electronics/control ) 
or PMSM (Permanent magnet synchronous motors )
