Embodiment Construction

[0012] In order to further understand the features and technical content of the present invention, please refer to the following detailed description and drawings related to the present invention. However, the drawings are provided for reference and illustration only, and are not intended to limit the present invention.

[0013] Such as figure 1 , figure 2 As shown, the main components of the synchronous motor rotor of the present invention include pole shoe 1 , damping ring 2 , damping strip 3 , high-strength connecting bolt 4 and pole body (with shaft) 5 .

[0014] from figure 1 It can be seen that a hole is processed in the pole piece 1 of the solid magnetic pole, and a damping strip 3 is pierced in the hole, and the damping strip 3 is short-circuited at the end with a damping ring 2 to form a full damping winding.

[0015] from figure 2 It can be seen that in the present invention, a hole for placing the damping strip 3 is opened on each pole shoe 1 according to the d...

Abstract

This invention provides a synchronous motor of a solid pole winding with damp, which comprises a pole body and a pole shoe, wherein the pole shoe is fixed on the pole body through a bolt; a hole is processed in the pole shoe; a damp strip perforates through the hole; the end part of the damp strip is welded with a damp ring; a copper strip damp winding is added on a rotor of a solid pole synchronous motor, equivalently, two sets of damp windings contribute action simultaneously when the synchronous motor is started; the synchronous motor disclosed by this invention can start a large-inertia blower and reduces risks possibly generated by the rotor in a starting procedure and expands a use range of the synchronous motor; the synchronous motor disclosed by this invention is characterized by simple structure, safe use and obvious action effect; the design of a pole shoe structure is changed, thus, a starting torque is increased, temperature rise is reduced, the performance of the motor is improved, and the safety of the motor is ensured.

Description

technical field [0001] The invention relates to a synchronous motor, in particular to a synchronous motor with a solid magnetic pole and a damping winding. Background technique [0002] In industrial production, there are a large number of fan loads that need to be driven by synchronous motors. Fans generally have a large moment of inertia. According to calculations, during the start-up process, the copper damping winding of an ordinary synchronous motor cannot meet the requirements when driving the fan. When the motor with large inertial load starts, the damping winding generates a lot of heat, and the ordinary cage damping winding will be melted and blown. Therefore, for fan loads, synchronous motors often use the structure of solid magnetic poles. The surface area of ​​solid magnetic poles is large, which is good for heat dissipation, and the steel pole shoes can withstand higher temperatures; the starting problem of some synchronous motors using solid magnetic poles has...
