Since they are connected in parallel, the armature and field windings are exposed to the same supply voltage. The efficiency of a dc motor depends on the power output. Initially with low power outputs, efficiency is poor due to the constant losses. As the output increases, the efficiency increases till it reaches a certain maximum value. If the output is still further increased, then the efficiency decreases due to the rapid rise in the variable losses.Power Equation Of A D.C. Motor The voltage equation of a d.c. motor is given by, V = E b + I a R a Multiplying both sides of the above equation by I a we get, This equation is called power equation of a d.c. motor. VI a = Net electrical power input to the armature measured in watts.Jan 26, 2022 · Brushless dc motors have an electrical time constant τ of a few hundred microseconds. The current will therefore have the time to react during each PWM cycle (see Figure 11). However, the mechanical time constant is in the range of a few milliseconds, so there is a factor of 10 between the mechanical and the electrical time constant. In our example input electrical power of the motor is 0.22 A x 6 V = 1.32 W, output mechanical power is 1000 rpm x 2 x 3.14 x 0.00126 N•m /60 = 0.132 W. Motor torque changes with the speed. At no load you have maximum speed and zero torque. Load adds mechanical resistance.Explain how the generator/motor and motor generator transition takes place in dc machines 2 6/17/2015 2 P em P e P oe =V t (I a ) Armature Field P shaft P fw P stray P coreP acir P b P f P fcl P shaft = total mechanical power developed at shaft (W) oe P fw = friction and windage losses (W) (from test) fcl P strayThe electric power input of an electric motor can be estimated using: Where: P in =Electric power input (Watts or W) I=Current (A) V=Applied Voltage (V) However, keep in mind that the formula above is only applicable to DC sources.
