Influence of the Type of Acceleration Characteristic of the Stepping Motor for Efficient Power Usage

The main goal of presented research is to confirm efficiency of nonlinear characteristic of frequency increase during start with full load of stepper motor. This paper discusses about characteristics commonly used during start of stepper motor and proposes nonlinear characteristic. Presented results are compared to criteria of total angular acceleration. Proposed acceleration characteristic use real torque-speed characteristic taken from stepper motor. Described method is applied to a machine that glues elements of complicated geometry. Usage of non-linear characteristic reduces productive time. Presented research was accomplished on prototype machine build for company, which produce seats for mass transportation. Due of diversity of elements in this process, the glue layer must always have the same parameters and setup time need to be as short as possible. Non-linear characteristic with variable frequency change is used to accelerate ball screw, which shift spraying system alongside machine.
