Long-term maintenance and disposal of shredder motor

The energy saving of the tire shredder motor is a systems project that involves the entire life cycle of the motor. When the motor is used in conjunction with the mechanical system, the efficiency of the motor is improved, that is, the design, development, and production of high-efficiency tire shredder motors have a better effect on the overall efficiency of the mechanical system, energy conservation and environmental protection.

 

Because the loss distribution of the motor of the tire recycling machine varies with the power and the number of poles, in order to reduce the loss of the tire shredder motor, we should focus on the main loss components at different power and number of poles. Some ways to reduce the loss are now Briefly described as follows:

 

1. Reduce the loss of the stator winding of the motor: increase the sectional area of ​​the stator slot and shorten the length of the stator winding end as much as possible.

 

2. Reduce the loss of the motor rotor winding: increase the cross-sectional area of ​​the rotor slot; reduce the resistance of the rotor winding.

 

3. Reduce the iron loss of the motor: use cold-rolled silicon steel sheet with good magnetic permeability to reduce hysteresis loss; use high-performance iron chip insulation coating.

 

4. Heat treatment and manufacturing technology. The residual stress after iron chip processing will seriously affect the loss of the motor. When processing silicon steel sheets, cut along the rolling direction of silicon steel sheets, and heat-treat the silicon steel punched sheets.

 

5.Reducing stray losses of the motor: reduce harmonics by improving the design of the stator winding; improve the design of the rotor slot and reduce harmonics; use magnetic slot mud or magnetic slot wedges to replace traditional insulating slot wedges and fill the motor with magnetic slot mud The stator core slot is an effective method to reduce additional stray losses.

 

6. Reduce friction loss and flow loss of the motor: use high-efficiency bearings; use efficient lubrication systems and lubricants; use advanced sealing technology.

 

In order to achieve the transformation from ordinary tire recycling machine motors to high-efficiency tire recycling machine motors and ultra-efficient tire shredder motors, in addition to measures such as increasing the use of silicon steel sheets and copper wires and reducing the size of fans, it must also be used in the application of new materials, tire recycling Machine motor manufacturing process and optimization design take measures to control costs and meet the constraints of tire shredder motor structure size.
