By Jack Marsh, Parker-TrilogyLINEAR MOTOR parameters can be confusing and difficult to understand, especially when different manufacturers use different methods to formulate and present them. This White Paper will use first principles, specifically the Lorentz Force Law and Faraday’s Law, to establish linear motor parameter formulations that are consistent and convenient to measure. It will also develop the relationships between certain motor parameters, show how some values differ depending on the winding type of the motor, and show how some parameters are not dependent on the winding type. Differences between peak-of-sine and RMS measurements will be examined. Simple ways to measure linear motor parameters will be shown. The formulas and relationships will then be compared with experimentally measured values to show their accuracy.
