How to design a motor with a given set of requirements?

  1. Nov 10, 2018 #1
    Let's suppose we are given a set of requirements and we are to design a motor that meets them. Requirements are:
    3 phase synchronous, 480v, 50Hz and of hysteresis type and alnico is the only available option and it should deliver a 0.6N.m output torque.

    Dimensions should not exceed 150 mm and air gap should not be smaller that 0.5 mm.

    Where to start the design? What should be the initial values to start with and are there any references that can give these typical values that later on will be tuned during the design steps? Is there any reference that offers a procedure for design of special motors like the one in question?

    If there are good books and references that you know of please let me know.

    Cordialy,

    If the supply system is a three phase system then a rotating magnetic field will be created in the air gap. The rotor will behave as an induction motor with solid steel rotor.
