Compound motor
It is possible to arrange for part of the field coil to be in series with the armature and part in parallel
This gives rise to a motor with a mix of the characteristics of shunt and series connected motors, the mix depending upon the armature connection point in the field winding.
Power production The mechanical power produced by a motor is: P = T . ω (power is in watts if torque is N.m and ω in rad/sec). Some of this will be lost due to friction and windage. The remainder is available as mechanical output power. The input electrical power that is converted to mechanical power is that due to the product of the back emf and the armature current.
HenceP = e. IaNote that e is not equal to the applied voltage, V. Some electrical power is dissipated due to the armature resistance and field coil resistance. (In an ac motor, other losses occur due to magnetisation and eddy current losses).
Determine the value of Resistance: Determine the value of R, so that the condition for resonance is fulfilled Figure Solution Admittance of first branch
