A drive is the electronic device that harnesses and 
regulates the electrical energy delivered to the engine. The drive feeds Electric Drive Motor china electricity in to the motor in varying amounts and at varying frequencies, thereby indirectly managing the motor’s velocity and torque.
So the the majority of economical choice would be a Three Phase Induction motor accompanied by a BLDC engine. I’d suggest BLDC ( because of its huge marketplace penetration recently,ease of availability and easier electronic devices/control ) or PMSM (Permanent magnet synchronous motors )
