Abstract
946,721. Adjustable cores; mounting electric motors. P. PENSABENE. Jan. 12, 1962, No. 1226/62. Heading H2A. In a motor-pump unit having a disc-type electric driving motor, high starting torque and quiet running are obtained by allowing the rotor to axially slide between stops to vary the air gap. As shown, the rotor 8 is in the starting position with an air gap 7 whose minimum length is set by end 15 of sliding bearing 11 abutting stop 14. When the motor is running at speed the difference in pressure between inlet 5 and outlet 6 of the pump effectively forces the rotor to the left until thrust washer 16 bears on flange 17 defining a larger air gap to give quiet running of the unit, Fig. 2 (not shown).
