Title:
MOTOR AND ROTOR THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/055163
Kind Code:
A1
Abstract:
A motor and a rotor (10) thereof. The rotor (10) comprises a support member (11), a magnetic conductive member (12), and permanent magnets (13). The magnetic conductive member (12) is arranged on at least one side of the support member (11) along the axial direction of the rotor (10) and is fixedly connected to the support member (11). The permanent magnets (13) are connected to the magnetic conductive member (12). The rotor (10) provided in the present application has the magnetic conductive member (12) and the support member (11). The magnetic conductive member (12) increases magnetic induction intensity. The support member (11) provides a certain supporting effect for the magnetic conductive member (12) and the permanent magnets (13), which is beneficial for increasing the output speed of rotation and torque of the rotor (10) and increasing the operational stability of the rotor (10). Furthermore, by means of configuring the support member (11) to be fixedly connected to the magnetic conductive member (12), the connection strength of the support member (11) and the magnetic conductive member (12) can be increased, thereby increasing the overall structural strength of the rotor (10). Under a working condition in which the rotor (10) operates at a high speed, the risk of the support member (11) and the magnetic conductive member (12) generating relative movement can be reduced, which is beneficial for increasing the highest speed of rotation of the rotor (10) and operational stability under high-speed operation.
