4.1 The whole set of equipment consists of IGBT intermediate frequency power supply (using water cooling), capacitor cabinet,
transformer, heating inductor, motor rotor bar brazing bed, temperature control system (including temperature control PLC,
man-machine interface operation screen) chiller. Its structure is as follows:
4.2 Introduction of heating sensor: According to the structural characteristics of the motor end ring, a unilateral bottom plane
heating inductor is used, the cooling method of the inductor is water cooling, and the heating part is embedded with a
high-frequency low-loss silicon steel sheet magnetic conductor to improve the heating efficiency.
4.3 Motor rotor bar brazing heating machine body The motor rotor guide bar brazing bed has sufficient rigidity and durability,
small thermal deformation, anti-fabrication and anti-corrosion, the lower frame is welded by section steel, and the platform
surface is covered with high-temperature epoxy glass fiber insulation board and heat-resistant mica board, anti-magnetic,
anti-magnetic hot. 4.4. Temperature automatic control system The automatic temperature control system is composed of an infrared temperature sensor with laser alignment, a temperature regulator, and an operating table, which is dedicated to short-wave copper metal measurement by a famous German brand (confidential).
