Counterweight support and motor applying the support

Abstract

The invention discloses a counterweight support and a motor applying the support. The counterweight support comprises a circular pedestal (1). A round surface of the circular pedestal (1) is uniformly provided with a plurality of counterweight block installation grooves (3). The counterweight blocks are inserted into the counterweight block installation grooves (3). Two sides of the counterweight block installation grooves (3) are vertically provided with ear plates (4). One ear plate (4) is provided with a positioning bolt hole (4.1). A bolt screwed into the positioning bolt hole (4.1) compacts the counterweight blocks on the other ear plate (4). By using the counterweight support and the motor applying the support, operation is simple and convenient and a shape is beautiful.

Description

technical field [0001] The invention relates to a counterweight bracket, in particular to a weight block mounting bracket for adjusting the counterweight of a motor (synchronous motor, asynchronous motor) to achieve dynamic balance and a motor using the bracket, belonging to the technical field of motors. Background technique [0002] At present, motor systems are widely used in industrial production. In 2010, the installed capacity of various motors reached 750 million kilowatts, so motors have become indispensable power equipment in industrial production; The motor has an essential process: the dynamic balance correction of the motor; [0003] The conventional correction method is: de-weight or increase the weight of the motor rotor; because the de-weight will affect the magnetic flux of the electronic rotor, the method of adding weight is generally used nowadays; the usual method of adding weight is to add a nut to the pad, or put an irregular pad The block (or weight gl...

[0003] The conventional correction method is: de-weight or increase the weight of the motor rotor; because the de-weight will affect the magnetic flux of the electronic rotor, the method of adding weight is generally used nowadays; the usual method of adding weight is to add a nut to the pad, or put an irregular pad The block (or weight glue) is fixed on the seal of the rotor. This operation is not only not standardized enough, but also has poor precision control. It needs multiple operations to meet the requirements of dynamic balance. Moreover, the appearance of the rotor after this operation is not beautiful enough, which affects its performance. It has certain adverse effects; in addition, because the conventional rotor magnets are fixed by adhesive bonding, it is not conducive to later replacement, which increases the difficulty and cost of later maintenance
