The 30W vibrating motor can achieve 20KG/0.2KN vibration force. Its bearings are precision machined from 45# high hardness steel to ensure that the motor can be stable output and improve its working efficiency. The internal rotor is made of all-cast aluminum, it is made of high-precision one-piece stamping, which makes the operation more stable and longer life. The vibration motor internal with pure copper lacquer wire, high temperature resistance, more powerful, low-noise operation, than the general ordinary motor mission to more fluent, not easy to break. Our vibration motor supports adjustable eccentric block angle to achieve stepless adjustment of vibration force. It can meet the vibration requirements in most work. High quality aluminum alloy casing, sealed slot design can be dustproof and waterproof. Anti-twist cable guard, double protection of power cord. This mini vibration motor is easy to operate and wired in a simple way: yellow and green wires are ground, blue wire is zero and brown is fire. voltage:110v Material: Metal colour: As shown Package Contents: 1 x Concrete Vibrating Motor Only the above package content, other products are not included.
