MID-I1. Draw and explain the operation and principle of PMMC Instrument?The permanent magnet moving coil instrument or PMMC type instrument uses twopermanent magnets in order to create stationary magnetic field. These types of instrumentsare only used for measuring the DC quantities as if we apply AC current to these type ofinstruments the direction of current will be reversed during negative half cycle and hence thedirection of torque will also be reversed which gives average value of torque zero. Thepointer will not deflect due to high frequency from its mean position showing zero reading.However it can measure the direct current very accurately. Stationary Part or Magnet System: In the present time we use magnets of high fieldintensities, high coercive force instead of using U shaped permanent magnet having softiron pole pieces. The magnets which we are using nowadays are made up of materialslike alcomax and alnico which provide high field strength.Moving Coil: The moving coil can freely moves between the two permanent magnetsas shown in the figure given below. The coil is wound with many turns of copper wireand is placed on rectangular aluminium which is pivoted on jeweled bearings.Control System: The spring generally acts as control system for PMMC instruments.The spring also serves another important function by providing the path to lead current inand out of the coil.Damping System: The damping force hence torque i
