The invention relates to a novel rotor position detecting module for a low-speed electric commercial vehicle driving motor. The module comprises a Hall angle sensor integrated chip, a peripheral circuit and an induction magnetic ring. The integrated chip is mounted on a stator end cover of a motor, the induction magnetic ring is mounted on an end of a rotor, and the integrated chip detects and collects a magnetic flux signal, performs angle data calculation, and transmits calculated data and a fault state to a controller MCU. The novel rotor position detecting module for the low-speed electriccommercial vehicle driving motor employed in the invention is suitable for a commercial vehicle platform with relatively low rotational speed. Compared with a rotary transformer scheme, an internal decoding chip of the controller and a peripheral complex circuit can be eliminated. According to the module, a rotary transformer and a resolver decoding chip with higher prices are substituted, the cost of a single set of electric drive system is significantly reduced, and at the same time, the good system performance and reliability can be ensured.
