Abstract: A vibration motor includes a housing, a stator (10) received in the housing (30) and a rotor (20) rotatably disposed in the stator. The stator includes two claw-pole assemblies (11) arranged back-to-back, and a shaft (23) being fixedly connected with the two claw-pole assemblies. The rotor includes a bearing (22) rotatably mounted around the shaft, a permanent magnet (26) mounted around the bearing, and an eccentric weight (24) fixedly attached to the permanent magnet. The eccentric weight includes a main body (240) and at least one inserting portion (244) having a density higher than that of the main body.

Abstract: A vibration stator includes a housing (30), a stator (10) received in the housing and a rotor (20) being rotatably disposed in the stator. The stator includes two claw-pole assemblies (11) arranged back-to-back and located at two opposite ends of the vibration motor symmetrically. Each claw-pole assembly includes two yokes (10a, 10b) each having a plurality of pole teeth (16a, 16b) extending therefrom and being intermeshed with those of the other yoke. The rotor includes a permanent magnet (26) and an eccentric weight (24) connected with the permanent magnet.
