A drive is the electronic device that harnesses and handles the electrical energy sent to the electric motor. The drive feeds electrical power into the motor in different amounts and at different frequencies, thereby Electric Drive Motor china indirectly managing the motor’s acceleration and torque.
So the many economical choice will be a Three Stage Induction motor followed by a BLDC electric motor. I’d suggest BLDC ( because of its huge market penetration in recent 
times,simple availability and easier electronics/control ) or PMSM (Long term magnet synchronous motors )
