Abstract

A high-temperature superconducting magnetic levitation motor is formed by a superconducting motor rotor (1), a motor stator (2), superconducting bearing rotors (3), permanent magnetic bearing stators (4), a rotary dewar (5), an electromagnetic screen (6), torque tubes (7), mechanical protection bearings (8), a main shaft (9), a low-temperature liquid (gas) inlet pipeline (10) and a low-temperature liquid (gas) outlet pipeline (11). The superconducting motor rotor (1) and the superconducting bearing rotors (3) are arranged in the rotary dewar (5) and are cooled by liquid nitrogen or liquid neon or liquid helium or cold helium, the motor stator (2) and the permanent magnetic bearing stators (4) are arranged outside the rotary dewar (5) and are coaxial with the rotary dewar (5), and the two mechanical protection bearings (8) are used in a left and right mode in the radial direction for protecting against the influence brought by the failure of superconducting bearings.

Description

technical field [0001] The invention relates to a high-temperature superconducting magnetic levitation motor. Background technique [0002] In order to realize the high-speed and reliable operation of the motor, the problem of high-speed bearings must be solved. Due to the contact, the mechanical bearing needs lubrication and maintenance, which limits its maximum speed and service life, and its high price has become the bottleneck of the high-speed electric drive. Conventional electromagnetic bearings have no contact and no lubrication, and have been effectively used in modern high-speed mechanical equipment. However, due to the large volume and excitation power of the electromagnetic bearing, the structural size and cost of the motor increase, and the critical speed decreases, which hinders the large capacity at high speed, and the dynamic response is slow, which limits its scope of application. The emergence of superconducting magnetic suspension bearing technology makes...
