Question
A dc shunt motor develops $30 \mathrm{~N}-\mathrm{m}$ of torque with $K_a \phi=1.4 \mathrm{~Wb}$. Find $E_a$ if $V_t=280 \mathrm{~V}$ and $R_a=0.16 \Omega$.
Step 1
We have: - Torque, \( T = 30 \, \text{N-m} \) - \( K_a \phi = 1.4 \, \text{Wb} \) - Terminal voltage, \( V_t = 280 \, \text{V} \) - Armature resistance, \( R_a = 0.16 \, \Omega \) Show more…

A permanent-magnet de motor has $R_{A}=$ $7 \Omega, V_{T}=240 \mathrm{V},$ and operates under noload conditions at a speed of 1500 rpm with $I_{A}=1$ A. $A$ load is connected and the spced drops to 1300 rpm. Determine the cfficiency of the motor under loaded conditions Assume that the losses consist solcly of heating of $R_{A}$ and frictional loss torque that is independent of speed.
A separately excited de motor (see the equivalent circuit shown in Figure 16.21 on page 788 ) has $R_{A}=1.3 \Omega$ and $V_{T}=220 \mathrm{V}$ For an output power of 3 hp $, n_{m}=950 \mathrm{rpm}$ and $I_{A}=12.2 \mathrm{A}$. The field current remains constant for all parts of this problem. a. Find the developed power, developed torque, power lost in $R_{A}$, and the rotational losses b. Assuming that the rotational power loss is proportional to speed, find the no-load speed of the motor
Consider a motor having the model shown in Figure 16.14 on page 781 . The motor runs at a speed of 1200 rpm and has $R_{F}=150 \Omega$ $V_{F}=V_{T}=180 \mathrm{V}, I_{A}=10 \mathrm{A},$ and $R_{A}=1.2 \Omega .$ Find $E_{A}, T_{\mathrm{dev}}, P_{\mathrm{dev}},$ and the power converted to heat in the resistances
