It depends on your personal preference and requirements, as well as the following considerations: The 2-phase stepper and the DC servo have a smaller ‘footprint’ than the 5-phase stepper. However, the 5-phase provides the greatest resolution due to the decreased step-angle from the 2-phase system. Additionally, the 2-phase and 5-phase have ‘holding torque’ inherent in the stepper design. The 2-phase will tend to get warm to the touch where the 5- phase will not, so if temperature is an issue consider the 5-phase. See motor options.
