vibration motors with 2 eccentric metal vibration heads(Note: Due to manufacturing reason, the iron heads could come with stain, if you are not satisfied with the order we will give you a full refund)
Rated Voltage: DC 12V; Speed(no load): 12V-4000RPM/min; Rated Voltage: DC 24V; Speed(no load): 24V-8000RPM/min
An eccentric rotating mass motor acts like a standard DC electric motor it transforms the flow of electrical current right into a mechanical pressure that turns the motor
Unlike a lot of DC motors, the ERM motor additionally has an off-center mass. Due to the fact that the turning of the off-center mass produces an asymmetric centripetal force, a non-zero centrifugal force is produced when the motor turns
As long as the motor runs at a high variety of turnings each minute, the constant variation of the pressure generates a perceivable side vibration
