Whenever a stepper motor is stepped, it resonates at a frequency of: where n is the number of poles of the motor, T is the restoring torque, and I is the inertia. However, we sometimes lose steps because of the heavy table. The control can be archived either by controlling the field current or armature current. This information is intended to provide basic information to technicians about a kind of motor ( known as step motor , stepping motor or stepper motor ) widely applied in precision machines, the industry, in minilabs to develop photography, printers, in sewing machines, etc.
