    The electric motor control system adopts sine wave vector control technology which features advantages like high efficiency, stability, low noise and easy installation. The series control devices can work with relatively smaller battery current while providing good acceleration and gradeability. Meanwhile, the regenerative brake system can gather the energy during brake, which can effectively increase the cruising mileage and reduce energy consumption. It adopts large power MOSFET high frequency design and its efficiency is up to 96%. It also features precision control with a powerful intelligent microprocessor.
