• Number Of Poles

    The distributed winding that is often used to provide 12 poles on a nine slot stator is suited for induction motors. In such a case the number of poles is selected before the winding work is started. Although small motors usually have four poles two pole motors are also used for high speed applications that require 50 or 60 rotations per second.

  • Three winding brushless DC motor with trapezoidal flux

    The rotor magnetic field due to the permanent magnets create a trapezoidal rate of change of flux with rotor angle. The figure shows this rate of change of flux. Back emf is the rate of change of flux defined by. d Φ d t = ∂ Φ ∂ θ d θ d t = ∂ Φ ∂ θ ω where Φ is the permanent magnet flux linkage. θ is the rotor angle.

  • Types of Electric Motors

    The AC electric motor converts AC Alternating Current electrical energy into mechanical energy. These electric motors are powered using a single phase or three phase alternating current. The basic working principle of AC motor is the rotating magnetic field RMF generated by the stator winding when an alternating current is passed through it.

    Determining Electric Motor Load and Efficiency

    Reasons to Determine Motor Loading Most electric motors are designed to run at 50 to 100 of rated load. Maximum efficiency is usually near 75 of rated load. Thus a 10 horsepower hp motor has an acceptable load range of 5 to 10 hp peak efficiency is at 7.5 hp. A motor ’s efficiency tends to decrease dramatically below about 50 load.
