Usually if you have full field the armature rpm is dependent on the armature voltage. If the power source can supply current enough for full load torque or stall torque, the motor endeavors to take all the power it needs to be at full speed. In short, if there is inertia in the load, you may break the motor's output drive couplings and gears if you don't limit the starting current by using a resistor.

describe how to use starting resistors to star a DC motor
Which motor has a higher starting torque?
A series-wound commutator motor has the best starting torque because the torque is proportional to the square of the current, and the starting current is set by a current-limiting resistor which is switched out as the motor builds up speed.
How do you know if the blower motor resistor is bad?
A malfunctioning blower motor resistor will cause the blower motor not to work. When the resistor is bad the blower motors will not turn on.
