Electric drive motor for pump and/or compressor - uses single point bearing for rotor so that other end of shaft can rotate free of bearing forces

摘要

The electric drive motor has a rotor (2) supported relative to the stator (3) via a single point bearing (4) at either the driven or driving end of the rotor shaft. Pref. the single point bearing (4) is provided by a roller-bearing provided by the motor housing end flange (6), or the radial piston pump, the opposite end of the rotor shaft (1) fitted with an electrical termination component (5), e.g. a brush holder integrated in the housing head of the stator (3). ADVANTAGE - Simplified mfr., reduced operating noise and easy servicing which are important factors when used in motor vehicles.
