AI Technical Summary
In existing flywheel energy storage devices, the contact area between the heat-absorbing component and the stator assembly is small, resulting in less heat absorption and affecting the structural stability and high-speed operation reliability of the rotor assembly.
The first and second cooling components, each including a first heat-absorbing element and a first heat-releasing element, a second heat-absorbing element and a second heat-releasing element, are arranged in a cross manner to contact the stator assembly in the circumferential direction, absorbing and dissipating heat to reduce the internal temperature of the motor.
It significantly reduces the internal ambient temperature of the motor, improves the structural stability and high-speed operation reliability of the rotor assembly, extends insulation life, and increases the power density and reliability of the motor.
