Abstract

The present invention provides a rotary table motor assembly and an electronic device. The rotary table motor assembly comprises a limiting member and two horizontally-arranged rotary table motors, each rotary table motor comprises a stator and an eccentric mover, the stator comprises a coil assembly, the eccentric mover comprises a rotating shaft and an eccentric wheel, and the coil assembly is arranged at the top and / or bottom of the eccentric wheel; the eccentric wheel comprises a magnetic assembly rotatably mounted on the rotating shaft, and the limiting member is used for abutting against the two eccentric wheels so as to limit the rotation angle of each eccentric wheel. According to the rotary table motor assembly, vibration sensation can be generated by means of an improvement in the structure of the eccentric wheels, facilitating the increase of the rotating speed of the motors and the reduction of energy consumption; additionally, asymmetric vibration can be generated in the working process by providing two horizontally-arranged rotary table motors.
