  • Permanent magnet motor with counterbalancing weights, shaft, and rotor
    Patent number: 10320250
    Abstract: Methods and systems to mount a shaft with a motor rotor are provided. The motor may include a plurality of permanent magnets embedded in a lamination stack of a rotor of the motor, which may run through the length of the lamination stack. The motor can include a shaft that may be coupled to the rotor in a center bore of the rotor. The shaft may be coupled to the rotor with a keyway. The shaft may be coupled to the rotor with a press fit. The shaft may be coupled to the rotor with a cold shrink fit. The motor may include a counter weight disposed on the shaft. The counter weight may help retain the shaft on the rotor. The embodiments as disclosed herein can help couple the shaft and rotor without using heat that may demagnetize the permanent magnets.
