• vibration motors with eccentric brass vibration heads
• Rated Voltage: DC 3V; Speed(no load): 3V-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
