ROTOR MANUFACTURING METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 18031211 titled 'ROTOR MANUFACTURING METHOD
Simplified Explanation
- The patent application describes a method for manufacturing a rotor of a rotary electric machine. - The method involves using magnets and a thermosetting resin to fix the magnets to a rotor core made of stacked steel sheets. - The process includes increasing the temperature of the rotor core to a curing start temperature or higher. - A resin injection apparatus is used to inject liquid resin at a melting start temperature or higher into the hole portions of the rotor core. - The rotor core is kept at the curing start temperature or higher to cure the resin and fix the magnets in place.
Original Abstract Submitted
A rotor manufacturing method for manufacturing a rotor of a rotary electric machine by disposing magnets in hole portions of a rotor core formed of stacked steel sheets, and injecting and curing a thermosetting resin to fix the magnets to the rotor core includes a temperature increasing step for increasing a temperature of the rotor core to a curing start temperature or higher, a resin injection step for causing a resin injection apparatus to inject the liquid resin at a melting start temperature or higher into the hole portions of the rotor core at the curing start temperature or higher, and a magnet fixing step for curing the resin by keeping the rotor core at the curing start temperature or higher.
