Torque production in DC machine

Torque production in DC machine

 Rotating machines require a steady torque for rotation. All Rotating Machines have two field one due to Armature winding and other due to Field winding. The necessary condition for steady torque production is that both fields must be stationery with respect to each other. If there is relative motion between the two fields then the torque produced is pulsating in nature and it has the frequency corresponding to the relative speed between the two fields.
The steady torque produced in any rotating machine is :-

T ∝ sin α , where α is electrical angle between the two fields. So, for maximum Torque production the angle between the two fields must be kept 90°.

Developed torque :-

 Developed power, Pa = Ea.Ia

 Pa = TꞶm

 Ea.Ia = TꞶm

T =Ea.Ia / Ꞷm = KⲫIa , (we know that, Ea = KⲫꞶm , where K=PZ / 2𝜋A)

T = KⲫIa

 Where,
 T= Developed torque
Pa= Developed torque
Ea= Average Induced emf in armature
Ia = Armature current
Ꞷm= Angular frequency of armature
ⲫ= Flux / pole (Wb)
P= Number of poles
Z= Total number of conductors
A= Number of parallel paths,  (A=2 for wave winding, A=P for lap winding )
K= Machine constant

Ideal Transformer (1-phase) Operation Under Load

 What is Ideal Transformer ? An ideal transformer is a transformer with the following assumptions: Permeability of transformer is infinite. Iron loss in the transformer core are zero. Resistance of transformer winding is zero. No magnetic leakage flux, so coefficient of coupling is  1 . Magnetization curve of transformer is linear. Operation of Ideal transformer under load Schematic diagram of an ideal, 1-phase transformer under load When a finite impedance load Z L   is connected across the secondary terminals of a 1-phase transformer as shown in above figure, the load current I 2   flows through the secondary winding and the load. load current I 2   is given by:- I 2  = V 2 / Z L How will MMFs Produce ? A voltage source V 1   is connected to the primary winding. Due to this voltage V 1  primary current I 1   flowing through N 1   number of turns in the primary winding produces an MMF  N 1 .I 1   which creates the flux Ⲫ in the core. This flux links with the secondary coil and induc

Compensating Winding

Compensating Winding The cross magnetizing armature reaction effect that causes concentration of flux under one pole tip is caused mainly by the conductors that lie under the pole are. When the machines are heavily loaded, the flux density at these tips become very high resulting in higher than normal induced voltage between concerned adjacent commutator segments. This may cause a spark over between adjacent commutator segments more so because these coils are physically close to the commutation zone where air temperature is high and favorable for spark over. This may lead to other segments also getting involved and resulting in fire over entire commutator segment. Also if load is rapidly fluctuating (e.g. rolling machine), L(di/dt) voltage of coils may became high enough to start a spark over between adjacent commutator segments. This phenomenon will start from the coil under the pole center and it would have maximum. This problem is more acute when load is decrea
