Description

Technical Field

[0001] The present invention relates to the technical field of synchronous motors, and in particular to a synchronous motor suitable for ultra-low temperature environments. Background Art

[0002] The synchronous motor for fans is an AC motor that generates torque by the interaction between the DC-powered excitation magnetic field and the rotating magnetic field of the armature, and rotates at a synchronous speed. The synchronous motor for fans is often used in an ultra-low temperature environment of -50℃.

[0003] The performance of existing synchronous motors will be affected to a certain extent when operating in ultra-low temperature environments.

In low temperature environments, the material of motor components shrinks due to the cold, and the insulation gap is reduced, making the motor prone to insulation failures.

[0048] Specific usage and function of this embodiment: In the present invention, when the motor body 1 is started, the rotor shaft 105 rotates, and the rotor shaft 105 drives the connecting sleeve 303 to rotate through the transmission groove 106 and the transmission bar 304, and the connecting sleeve 303 drives the horizontal axis 401 to rotate, and the horizontal axis 401 drives the annular array magnetic plate A404 and the magnetic plate B405 to rotate through the mounting seat 402 and the cylinder 403, so that the magnetic field inside the spiral copper tube 505 continuously changes, thereby generating current inside the copper tube 505, and the current heats the water inside the copper tube 505; at the same time, the horizontal axis 401 drives the fan blades 603 through the auxiliary rod 601 and the auxiliary cylinder 602 and the connecting bar 605 and the connecting groove 604. The fan blades 603 blow the heat generated by the water inside the copper tube 505 toward the motor body 1, thereby heating the working environment of the motor body 1, which is beneficial to prevent the motor body 1 from operating in a low-temperature environment for a long time. When the water in the copper tube 505 is heated, the water in the copper tube 505 expands and circulates through the one-way valve A502 and the one-way valve B503 installed in opposite directions and the vertical pipe 504, which is beneficial to prevent the copper tube 505 from bursting or insufficient water. When the working environment temperature of the motor body 1 continues to rise and reaches a certain temperature, the mercury between the inside of the fixed cylinder 202 and the piston plate 203 expands due to the heat, causing the piston plate 203 to push the sliding rod 204 outward, and the sliding rod 204 is pushed outward. The movable rod 204 pushes the fixed ring 302 through the connecting arm 301, so that the connecting sleeve 303 is disengaged from the rotor shaft 105; thereby, the magnetic plate A404 and the magnetic plate B405 stop rotating, and the working environment temperature of the motor body 1 stops rising; when the working environment temperature of the motor body 1 drops again, the mercury contracts, and at the same time, the spring member drives the sliding rod 204 and the piston plate 203 to reset, so that the transmission bar 304 slides back into the transmission groove 106 by using the end chamfer, thereby causing the magnetic plate A404 and the magnetic plate B405 to rotate again, so that the working environment of the motor body 1 is heated again; at the same time, the two sets of protective covers 701 are pushed inward, so that the locking block 707 is supported by the connecting seat A703. The extrusion causes the locking block 707 to slide into the locking seat 706 using the end bevel structure; when the two sets of protective covers 701 are in contact with each other, the spring member drives the locking block 707 to slide into the locking hole 704, so that the two sets of protective covers 701 are fixed; and then the protective cover 701 and the thermal insulation layer on the protective frame 103 and the inner wall thereof can be used to protect the motor body 1; the linkage seat 7010 is pulled upward, and the linkage seat 7010 drives the two sets of locking blocks 707 to move in the opposite direction through the two sets of linkage plates 709 and the two sets of positioning plates 708, so that the two sets of locking blocks 707 slide out of the locking hole 704 at the same time, and then the two sets of protective covers 701 can be disassembled, which is conducive to the later maintenance of the components inside the protective frame 103.
