motor torque developed and the load torque. The motor torque is a function of the applied voltage during starting conditions, and the load torque usually varies with speed. The rate of accel eration is proportional to this torque difference, and the motor will hang up at a low speed value if the torque differential reaches zero.
Here are 3 main types of vibrations that stepper motors exhibit. Low speed vibration (about 0~50 RPM is caused by step movement; Mid-speed vibration (about 50~200 RPM) is caused by torque variance or resonant frequency; High speed vibration (about 500 RPM and above) is caused by back EMF and instability of constant current control.
Torsional vibration is angular vibration of an object—commonly a shaft along its axis of rotation. Torsional vibration is often a concern in power transmission systems using rotating shafts or couplings where it can cause failures if not controlled. A second effect of torsional vibrations applies to passenger cars. Torsional vibrations can lead to seat vibrations or noise at certain speeds.
More stringent specifications regarding motor vibration call for maximum velocity levels of 0.1 in./sec on the housing and 1.5 mils of displacement vibration on the shaft. The limits apply to a motor mounted on a seismic mass, and uncoupled or coupled to a piece of equipment in a way that eliminates any vibration in the driven equipment.
