More Information
Summary:An electric pump is provided, which includes a housing, a shaft, a rotor assembly and a stop assembly. The shaft is fixed to the housing, the rotor assembly is rotatable about the shaft, and the rotor assembly is sleeved on the shaft. The stop assembly is configured to limit the position of the rotor assembly in the chamber. The stop assembly includes a first stop and a second stop, the first stop is fixed with respect to a second portion of the shaft, and the second stop is fixed with respect to a first portion of the shaft. No relative movement occurs between the stop assembly and the shaft, which reduces the abrasion between the stop assembly and the shaft resulted from friction, and facilitates improving a service life of the stop assembly.
