Description

Double-output shaft type motor Technical Field The utility model belongs to the technical field of motors, and particularly relates to a double-output-shaft motor. Background The double-output shaft motor is used as a power output device, and is widely applied to the fields of industrial equipment, automatic machinery, robots and the like due to the characteristic that torque can be transmitted at two ends of the double-output shaft motor, and is particularly suitable for scenes requiring bidirectional synchronous driving or limited space. However, the terminals of conventional double-output shaft motors are typically of a straight-out design, i.e., the terminal sets extend outwardly perpendicular to the motor end caps. Although the structure can meet the requirements in the conventional application, when external equipment such as a speed reducer and the like is required to be installed at two ends of a motor, the straight-out connecting terminal can interfere with the installation space of the speed reducer, so that the speed reducer cannot be directly attached to the motor end cover, and even the speed reducer shell or the connecting flange is forced to be subjected to nonstandard design (such as an avoidance groove is additionally arranged, an installation hole site is adjusted, and the like), so that the customization cost and the structural complexity of the speed reducer are increased.
