Medium-frequency internal and external simultaneous heating equipment for rotor core of new energy motor

Abstract

The invention discloses a new energy motor rotor core intermediate frequency internal and external simultaneous heating device, which comprises a box body, a heating extension inverter is arranged at the upper part in the box body, a touch screen control box is fixedly mounted at the upper end of the outer side wall of the box body, and the touch screen control box is in electric control connection with the heating extension inverter through a wire. A heating power source is arranged on the lower portion in the box body, a bearing plate is arranged outside the box body, a hydraulic cylinder is installed at the upper end of the bearing plate, a set frame is fixedly installed at the lower end of the bearing plate, a bottom plate is fixedly installed at the lower end of the set frame, and a rotor heating inductor is fixedly installed at the lower end of the bottom plate. The efficiency is greatly improved by internal and external simultaneous heating, and the external heating coil not only directly conveys heat to the outer circle of the rotor iron core, but also reduces heat source leakage from the aspect of heat dissipation, so that the problem of low efficiency or chip explosion caused by only heating the inner hole traditionally is greatly met and compensated, and the process is improved.

Description

technical field [0001] The invention relates to the technical field of distribution boxes, in particular to a new energy motor rotor iron core heating device at the same time inside and outside at intermediate frequency. Background technique [0002] Due to the great difference in the stacking height of motor products, some users have many stacking quantities, but the outer circle and inner diameter of the rotor core are the same, so if the coils are often replaced according to different heights, it will take a lot of work and time; if the coils are not replaced, the height of the coils will be different from the actual The large difference in the height of the heated stacked rotor cores will cause the temperature difference between the upper and lower rotor cores to be too large after heating. Therefore, the induction coil of the high-end model we designed can be raised and lowered by a servo at a constant speed during heating, and a constant speed rotation device is install...
