Radial sensor installation structure of magnetic suspension motor

Abstract

The invention discloses a radial sensor installation structure of a magnetic suspension motor. The radial sensor installation structure comprises a radial sensor plate, a displacement sensor, a platinum thermistor, a plug and an annular radial sensor radiator, wherein the radial sensor radiator is provided with a limiting groove and an annular installation groove; the radial sensor plate is arranged in the annular installation groove and one end extends into the limiting groove; a first installation hole, a second installation hole and a pouring hole, which run through the annular installation groove are formed in an inner ring wall of the radial sensor radiator; the displacement sensor and the platinum thermistor are arranged in the first installation hole and the second installation hole respectively and are connected with the radial sensor plate; and the plug is tightly connected with the pouring hole. According to the radial sensor installation structure, the structure is simple; the radial sensor plate, the displacement sensor and the platinum thermistor all are arranged on the radial sensor radiator, and radial sensor assemblies are arranged on the magnetic suspension motor after being integrated, so that the contact surface of the radiator is increased, the heat-dissipation area is increased and cooling of the radiator is accelerated.

Description

[0001] Technical field: [0002] The invention relates to a radial sensor installation structure of a magnetic levitation motor. [0003] Background technique: [0004] In the existing centrifugal motor, the radial sensor and the magnetic bearing are integrated. Affected by the existing structure, the temperature of the radial sensor is high during the operation of the motor, which is easy to be damaged, which greatly reduces the use of the sensor and the magnetic bearing. Life, but also reduces the safety and reliability of the machine. [0005] Therefore, it is necessary to improve the prior art to solve the deficiencies of the prior art.
