Motor Rotor Heater
Used for batch induction heating assembly of parts with relatively small inner holes or blind holes such as rotors, causing them to expand with heat to meet the requirements of interference fit assembly. It is an induction heater truly suitable for long-term assembly on production assembly lines, capable of adapting to most harsh working environments. Our company specializes in producing motor stators and rotor heaters. This product helps the motor pump industry, solving the biggest difficulty of rotor shaft assembly during motor pump assembly line assembly. It can be used for motors ranging from the smallest fraction of a kilowatt to hundreds of kilowatts, greatly facilitating our friends in the motor industry.
Many motor rotors are damaged during installation, and improper assembly methods are one of the important reasons. For example, press installation can easily damage the rotor; furnace heating results in uneven heating; oil bath heating can contaminate the bearing due to unclean oil, increasing noise; oven heating is too time-consuming. As for hammering installation, high-frequency heating has weak penetration. It uses the eddy current generated by metal in an alternating magnetic field to heat the rotor itself. The principle is that when thicker metal is in an alternating magnetic field, current is generated due to electromagnetic induction. After current is generated in thicker metal, the current forms a spiral flow path inside the metal, and the heat generated by the current flow is absorbed by the metal itself, causing the metal to quickly heat up and expand to meet interference fit requirements.
