WebFigure 5 Losses in a DC motor. DC Motor Back EMF Calculation Example 4. Figure 6. Figure 6 Circuit for Example 4. DC Motor Efficiency Calculation Example 5. A 250 V DC long-shunt, compound motor takes a current of 82 A at full load. Calculate the output power and the efficiency, given the following details: shunt field resistance = 125 Ω WebThe efficiency curve is of the same shape as all electric motors and generators. The torque is directly proportional to the armature current i.e. if twice full load torque is required at starting, then shunt motor draws twice the full load current.

WebOct 1, 2009 · Increasing the shunt motor speed by reducing armature resistance (armature control) reduces the running cost but increases the efficiency from its original values to ₦238.70 and 82.89% ...
Web2 days ago · The field winding in shunt DC motors is made of many windings of thin wire, to both increase the magnetic field’s strength and limit the current through the coil. By doing so, the current is reduced through the field coil and thus increases in the armature (remember, the current is shared when in parallel). The larger current in the armature ... img sock on tseWebAug 13, 2024 · Condition for Maximum Mechanical Power. The mechanical power developed by the motor (neglect mechanical losses) is given by, P m = E b I a. ⇒ P m = V I a I a 2 R a. Since, the V and Ra are constant for a given machine, hence the mechanical power developed by the motor depends upon the armature current. The condition for maximum … img soccer showcase 2021WebFigure 2 shows torque as a function of armature current for a shunt DC motor. As was the case with the speed, however, the armature reaction has an effect. As the armature current increases, the flux per pole decreases, causing the electromagnetic torque to be somewhat lower than expected.
