ELECTRIC MOTOR WITH MULTIPLE IN-LINE STATORS AND/OR ROTORS

摘要

An electric motor (100) having at least two in-line stators (102, 104) and at least two-inline rotors (106, 108) cooperative with each other. The rotors (106, 108) are mounted to a common shaft that may be hollow. The second stator (104) is offset from the first stator (102) along the common shaft (110) and the second rotor (108) is offset from the first rotor (106) along the common shaft (110). The in-line stators (102, 104) can be operatively coupled to the same drive-controller (111) or separate drive controllers (118, 120) and can be energized concurrently or independently. During deceleration of the shaft the first stator (102) and the first rotor (106) can act as a regenerative brake.
