Why does the motor stall during no load testing?
The motor needs inertia roughly equal to its
own inertia to accelerate properly. Any
resonances developed in the motor are at their
worst in a no-load condition.
What are the options for eliminating
resonance?
This would most likely happen with full step
systems. Adding inertia would lower the
resonant frequency. Friction would tend to
dampen the modulation. Start/stop velocities
higher than the resonant point could be used.
Changing to half step operation would greatly
help. Ministepping and microstepping also
greatly minimize any resonant vibrations.
Viscous inertial dampers may also help.
