Abstract

The invention relates to an integrated double-output coaxial motor and belongs to the field of electric motors, in particular to an integrated double-output coaxial motor with two output shafts mounted on the same axis. The coaxial motor comprises a front motor, a rear motor, a housing, a front end cover component and a rear end cover component, wherein the housing is a cylindrical structure with two opening ends, a partition board in the middle of the housing divides the housing structure into a left inner chamber and a right inner chamber; the front motor is mounted in the left inner chamber of the cylindrical housing, and the rear motor is mounted in the right inner chamber of the cylindrical housing; the front motor comprises a front motor stator, a front motor rotor and a front motor rotor output shaft; the front motor rotor output shaft is a stepped hollow shaft; the rear motor comprises a rear motor rotor output shaft, a rear motor stator and a rear motor rotor; and the rear motor rotor output shaft is a solid shaft. The coaxial motor has the characteristics of compact structure and larger output shaft radial stiffness; and the coaxiality of the rear motor rotor output shaft and the front motor rotor output shaft is high.

Description

technical field [0001] The invention belongs to the field of electric motors, and in particular relates to an integrated double-output coaxial motor with two output shafts installed on the same axis. Background technique [0002] Each output shaft of the coaxial motor is located on the same axis, and each output shaft is independently controlled, that is, the output speed and torque of each shaft are independent of each other. It is mainly used in occasions with special requirements for the space size and quality of the motor. For example, a coaxial motor group involved in patent CN201010003554.9, multiple groups of motors are connected in series and output on the same axis, the rotating shaft of the motor with a solid rotating shaft passes through the rotating shaft of a motor with a hollow rotating shaft, each group The motors are independent of each other. Except for the first motor at the front end, the output shafts of the other motors have a large overhang length and l...
