A drive is the electronic device that harnesses and regulates the electrical energy delivered to the engine. The drive feeds electrical power into the motor in various amounts and at different frequencies, thereby indirectly managing the motor’s quickness and torque.

So the the majority of economical choice would be a Three Stage Induction motor accompanied by a BLDC engine. I’d suggest BLDC ( because of its huge marketplace penetration recently,ease of availability and Electric Drive Motor china easier electronics/control ) or PMSM (Long lasting magnet synchronous motors )
