DC Brushed Motors The original DC motor and still the best suited for many applications.   You get bags or torque by giving it current (they develop a maximum torque when stationary, linearly decreasing as speed increases). Brushed DC motors generally have lots of commutators.  This means they are often superior for low RPM […]

PSU Votlage A motor will only go as fast as you have volts to apply (with no loading taken into consideration), so whilst you can run a DC motor and its drive at below its rated voltaged, the maximum speed possible will reduce.  This can usually be calculated from a motors RPM/V specification and this […]
