The synchronous motor system which makes torque output increase making use of the asynchronous motor

摘要

(57) Abstract The traffic circle actuator, desirably from the synchronous motor where output speed consists of the fixed AC motor and the asynchronous motor which consists of the DC motor of the auxiliary capacity which supplies addition torque to load desirably obtains Drive power. Although the method which maintains the portion of largest torque making use of the asynchronous motor of a certain genus, obtains that largest necessary torque rather than using the synchronous motor of sufficient size, low it reaches cost. By using the torque limitation clutch which joins asynchronous motor output with synchronous motor output, to operate the asynchronous motor with the compatibility of the synchronous motor, it is possible. As a torque limitation clutch, those of hysteresis coupling die are desirable. Regarding the configuration of one execution, with the both motor, Drive the gear train, it joins the asynchronous motor to the said gear train with the torque limitation clutch.
