Vibrating, again by definition, means “to move back and forth rapidly.” The equipment and process solutions described in this guide all use this rapid “back and forth” motion to move or convey product. On a vibratory feeder, material is “thrown” up and forward so that it drops to the surface at a point further down the tray

AB-004 Understanding ERM vibration motor characteristics. Overview. The Eccentric Rotating Mass vibration motor, or ERM, also known as a pager motor is a DC motor with an offset (non-symmetric) mass attached to the shaft.. As the ERM rotates, the centripetal force of the offset mass is asymmetric, resulting in a net centrifugal force, and this causes a displacement of the
To calculate load torque, multiply the force (F) by the distance away from the rotational axis, which is the radius of the pulley (r) . If the mass of the load (blue box) is 20 Newtons, and the radius of the pulley is 5 cm away, then the required torque for the application is 20 N x 0.05 m = 1 Nm. Typically, a safety factor is used so that the
