			In summary
			*Servo motors are suitable for high speed and high acceleration requirements. The trade-off is a higher cost and complexity.
			*Stepper motors are suitable for low speed and low acceleration requirements.
			*DC motors are suitable for continuous rotation at high RPMs and constant torque across the motor’s speed range.

			=Step 3) Dimension the motor=
			Once the motor type has been selected, the motor has to be "dimensioned" or "sized." This means that we need to select a motor that is of the right size and power.

			An underdimensioned motor will not provide enough [[torque]] for the intended application to be performed or be under too much stress leading to a reduced lifespan for the motor. A motor that is overdimensioned will cost more than needed, increase energy usage and be inefficient.

			The steps for dimensioning the motor will depend on the which motor type was selected in Step 2 of this article. Follow the link to the dimensioning guide correspodning to the selected motor type below:

	Besides defining the Load requirement (in earlier steps), we must also define the requirement for the Motion of the drive-mechanism carrying that Load. Just because a motor can provide enough torque for a mechanism to move an object that weighs 20 kilos doesn’t necessarily mean it is able to do so in a restricted time frame of 3 seconds over a distance of 400 mm. Therefore we must define such motion requirements via something called a Motion profile.
