Abstract
The utility model discloses an energy -conserving cast copper pole or cast copper pipe electric motor rotor, rotor groove, the end links at iron core both ends and the radiator shutter on the end links on the rotor yoke that cup joints in proper order outward including the pivot and iron core, the iron core, the rotor inslot is equipped with copper pole or copper pipe. The utility model discloses utilize the motor start with the skin effect principle of operation in -process, improve rotor flute profile form, increase copper pipe or copper pole at the rotor inslot, make it in the motor start -up course, the high impedance of rotor outside aluminium winding and reduce starting current and improve starting torque, skin effect reduces during normal operating, from the near copper winding cutting stator magnetic line of force of rotor yoke, the little heat conduction of impedance is fast, therefore the motor speed is high, overload capacity is strong, the temperature rise is low, rotor core need not to preheat, has reduced rotor core's loss promptly, has more crucially improved operational safety and work efficiency, through handling at copper inside pipe wall outer wall or the tin -plating of copper pole outer wall, fully contact with aluminium liquid when being convenient for the rotor cast aluminium.
Description
Technical field
The utility model relates to a kind of rotor, particularly relates to a kind of energy-conservation cast copper bar or cast copper pipe rotor.
Background technology
Motor is most popular power source, is generally applied in various plant equipment.According to interrelated data display, total use amount of the current motor of China has accounted for more than 60% of total electricity consumption, along with the quick propelling of world's energy-saving and emission-reduction paces, popularization and use ultra-high efficient motor, and improves constantly Motor Energy Efficiency level and becomes trend.
Fine copper has excellent electric conductivity, its resistivity is lower than aluminium by 40%, copper rotor is adopted to replace cast-aluminum rotor to be considered to improve the optimal selection of middle-size and small-size motor efficiency, but pure copper casting rotor complex process, rate of finished products is low, and cost is high, dynamic balance checking efficiency is low, rotor core preheating causes iron loss to increase, and affects the many factors such as the level of efficiency of motor, hinders the large area marketing of copper casting rotor motor.
Summary of the invention
The utility model provides a kind of energy-conservation cast copper bar or cast copper pipe rotor for the defect of prior art, its object is utilize the skin effect principle in motor start-up and running to improve rotor, copper pipe or copper bar is increased in rotor, make the high impedance of its aluminium winding outside starting process of motor rotor and reduce starting current raising detent torque, during normal operation, skin effect reduces, from the copper winding cutting stator magnetic line of force close to rotor yoke, because the little heat conduction of its impedance is fast, motor has the advantages that rotating speed is high, overload capacity is strong, temperature rise is low.
The utility model is for realizing above object, adopt following scheme: a kind of energy-conservation cast copper bar or cast copper pipe rotor, comprise the radiator shutter on the rotor on rotor yoke that rotating shaft is socketed successively and iron core, iron core, the end ring at iron core two ends and end ring outward, it is characterized in that, in described rotor, be provided with copper bar or copper pipe.
Preferably, described rotor is bar-shaped trough near iron core external diameter one end, and it is cylindrical groove near iron core internal diameter one end, and described copper bar or copper pipe are plugged in described cylindrical groove.
Preferably, described copper pipe is the equal tin-plated copper tubes of inside and outside wall.
Preferably, described copper bar is outer wall tin-coated copper bar.
Preferably, described copper bar or the alignment of copper pipe both ends extend to iron core two ends.
Preferably, cast aluminium in described rotor.
Preferably, described end ring outer surface cast aluminium.
Preferably, described bar-shaped trough groove gap is less than copper bar or copper pipe diameter.
The beneficial effects of the utility model:
1, the utility model utilizes the skin effect principle in motor start-up and running, improve rotor shape, copper pipe or copper bar is increased in rotor, make it in starting process of motor, outside rotor aluminium winding high impedance and reduce starting current and improve detent torque, normal when running skin effect reduce, from the copper winding cutting stator magnetic line of force close to rotor yoke, the little heat conduction of impedance is fast, and therefore motor speed is high, overload capacity is strong, temperature rise is low.
2, the utility model implements rotor iron core without the need to preheating, and namely reduce the loss of rotor core, more crucial is improve processing safety and operating efficiency.
3, pass through in copper pipe inwall outer wall or the zinc-plated process of copper bar outer wall in the utility model, fully contact with aluminium liquid when being convenient to casting aluminum rotor.
