Variable-frequency speed control motor for hybrid electric vehicle

The invention provides a variable-frequency speed control motor for a hybrid electric vehicle, which belongs to the technical field of hybrid electric vehicle motors, and driving couple and clutch devices, and mainly aims to solves the problems that the service life of an auxiliary power motor shaft adopting the conventional structure is seriously influenced due to great impact, and accident potentials exist. The variable-frequency speed control motor is mainly characterized by comprising a main power motor, an auxiliary power motor and a driving couple and clutch device; a second shaft sleeve, a second release fork, a second shift lever, a second release arm and a second release bearing seat are arranged at the rear end of the auxiliary power motor; and the second release arm is coupled with a second cylinder arranged on the auxiliary power motor. The variable-frequency speed control motor has the characteristic that when the auxiliary power motor shaft is in the state of being probably impacted, the second
