    EXERCISE 1.1
    (DC MOTOR MACHINE - LOAD )

    A 240V separately excited - wound DC motor runs at 1750 rpm at no load speed and takes
    0.9A. The armature resistance and field resistances are 0.78 Ω and 150 Ω respectively.
    Assumed magnetic flux is constant, the motor torque constant is 0.9, while the nominal power
    output of the motor is 5HP.

    From the above,

    1) Extract the parameter specification of the DC motor and illustrate in a table.


    2) Define the speed of the motor in (rad/s) with no load applied (when supplied is 240V)
    3) Define the no-load current.
    4) Determine the total load torque (TL) when it is operating at nominal power. You may
    use the formula listed below.
    5) Using MATLAB – Simulink, develop the block diagram shown in Figure 2. Then, do
    the following:
    i) For the load torque (TL) defined in Table 1.1, find the following and complete
    the table:
    a. Time (t) sec to reach the steady-state speed.
    b. Motor Speed (rpm) at steady state
    c. Motor torque (Ta) in Nm at steady state
    ii) Plot the graph – Input (TL) and output (speed) for each TL in Table 1.1, and
    explain the behaviour.
    Table 1.1

    Load Torque (TL) Time (t) sec to Motor Speed (rpm) Motor torque (Ta) in Nm
    in N-m reach the steady At steady state At steady state
    state speed
    TL = 0
    TL = TL
    TL = TL/2
    TL = TL/4

    Formula.

    TL = Pout/𝜔,

    whereby;
    TL = Total load torque (N.m)
    Pout = Power output (Watt)
    𝜔 = speed (rad/s)

    Note:
    • The motor torque is proportional to armature current.
    • 1 HP = 746W
