APPARATUS FOR MEASURING PROPULSIVE FORCE OF LINEAR PULSE MOTOR

摘要

PURPOSE: An apparatus for measuring a propulsive force of a linear pulse motor is provided, which measures a more accurate positive propulsive force characteristics by adopting a synchronous motor which is controlled accurately. CONSTITUTION: A positive propulsive force measurement apparatus(10) of a linear pulse motor comprises a pressure unit(S) comprising a load cell(13) to measure a load data and a potentiometer(14) to measure a movement displacement of a mover(22). The pressure unit is constituted with a synchronous motor, which is a kind of AC motor rotating with a synchronous speed and its rotation is varied by changing a power supply voltage frequency.
