I don't think you understand the point of PWM then which is ok. A resistor wouldn't provide runtime control of the power going to the motor, unless you had a programmable resistor which would likely explode from the current induced heating. And that's fine, because everybody just uses PWM, but if you do a follow-up I recommend investigating why the motor is connected and controlled in the way you did it.
