ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to an electric motor in which transmission of vibration between a stator and a base is attenuated.
A known electric motor includes a magnetic field assembly or stator which is enclosed by an armature assembly or rotor. A shaft is connected to the rotor and extends through the stator. O-rings are disposed between components of the stator to provide vibration isolation. An electric motor having this construction is illustrated in U.S. Pat. No. 5,235,227. Other known electric motors are disclosed in U.S. Pat. Nos. 4,082,974 and 5,315,200.
SUMMARY OF THE INVENTION
The present invention relates to an electric motor having a base and a stator connected with the base. A rotor is rotatable relative to the stator under the influence of magnetic forces transmitted between the rotor and stator. Resiliently deflectable members are disposed between the stator and the base to reduce transmission of vibration between the stator and the base. The resiliently deflectable members may be spring pins.
